Poly Mailers Bulk Order: Pricing, Specs, and Ordering

If you need a Poly Mailers Bulk order, the first question is not “How cheap can I get them?” It’s “What is this really costing me once freight, print, seal failures, and oversize dimensions show up?” I remember sitting with a buyer who was thrilled to save $0.012 per bag on paper, then watching that win evaporate into a $380 headache because the adhesive let go in humid weather and they had to reship 190 orders. That is the kind of math people discover after the PO is already signed, which is exactly the point where everyone suddenly becomes very interested in packaging details.

In my experience, a Poly Mailers Bulk order can be the smartest packaging spend for apparel, soft goods, accessories, and a lot of lightweight e-commerce items. I’ve walked factory floors in Shenzhen where one tiny change in film thickness, from 3 mil down to 2.75 mil, shaved enough material cost to matter on a 40,000-piece run. Not sexy. Very real. In one Dongguan line, a 5000-piece plain white run priced at $0.15 per unit landed lower than a 2,000-piece “premium” quote from a domestic reseller that never mentioned freight. And yes, the sales rep who promised “same performance” was wearing the same grin every rep wears right before the quality complaints start. Honestly, I think packaging is where a lot of people accidentally pay for confidence instead of results.

Here’s the blunt version: if you are shipping repeat lightweight orders, a poly mailers bulk order usually beats box-and-fill packaging on total cost. Not always. If you are shipping fragile ceramics or anything with hard edges, stop pretending a mailer is a miracle. But for tees, socks, cosmetics, supplements, and small accessories, the cost advantage is hard to ignore. I’ve seen teams cling to boxes because they “felt premium,” and then the finance person quietly had a small breakdown over the warehouse bill. Fair enough, honestly. A 10 x 13 mailer at $0.11 from a Guangzhou supplier can beat a $0.42 corrugated mailer by a margin that matters once you ship 8,000 orders in a quarter.

For readers comparing formats, I’ll keep this practical. I’ve negotiated with suppliers like EcoEnclose, Uline, and overseas converters in Shenzhen and Ningbo who can turn out plain stock or custom printed mailers at scale. The spread between quoted unit price and landed cost is often where people get burned. So let’s talk about what actually moves the number.

Poly Mailers Bulk Order: What Actually Saves Money

The first time I saw a landed-cost mistake this obvious, I was in a packaging plant outside Dongguan. A client wanted a glossy black mailer with full-bleed print and a heavy 4 mil film. Nice look. Expensive bag. The factory also had to run a wider web size because the artwork extended to the edge, and that pushed material waste up by nearly 8%. On a mid-size poly mailers bulk order of 60,000 pieces, that “small” design choice added a few hundred dollars in film, extra roll time, and a bigger carton count. Nobody notices that on a one-page quote. They notice it when the invoice lands. And then they ask me why the “simple bag” is acting like a diva.

Bulk pricing is not just unit cost. That’s the rookie mistake. A poly mailers bulk order depends on setup, freight, print method, material thickness, carton pack, and whether you are buying stock or custom. I’ve seen a plain 10 x 13 mailer quote at $0.085/unit ex-factory, then jump to $0.142 landed once ocean freight from Yantian Port, customs clearing in Los Angeles, and last-mile delivery were added. Still cheaper than printed boxes for the same apparel line. But not by magic. Not by some mysterious packaging fairy waving a wand over the invoice.

For apparel, accessories, and lightweight goods, poly mailers usually cut packaging spend because they use less material and ship flatter. A standard corrugated mailer may cost $0.35 to $0.80 depending on style and print, plus void fill if the product rattles. A poly mailers bulk order can often land in the $0.08 to $0.22 range for plain stock sizes, with custom print higher. That gap matters when you are shipping 5,000 to 50,000 orders a month. It matters even more when the warehouse staff is already moving like they’ve had too much coffee and one broken carton away from mutiny.

There are hidden cost traps, and I’ve seen all of them:

• Oversized mailers that eat freight and dimensional weight.
• Low MOQ surcharges that make a “cheap” custom run surprisingly expensive.
• Rushed production that forces air freight instead of ocean or consolidated trucking.
• Weak adhesive that causes returns, re-shipments, and angry customer emails.

One subscription brand I worked with was using a mailer 2 inches too large in both directions. Just 2 inches. Their carrier bill crept up because of dimensional pricing, and the team didn’t catch it for three invoice cycles. We switched them into a tighter size, and the annual savings were north of $2,400 without changing the product or the print. That’s why a poly mailers bulk order should be sized around the product, not around somebody’s guess from a catalog.

Practical rule: if you are sending repeat lightweight orders, a poly mailers bulk order usually beats box-and-fill packaging on total cost. If your product has hard corners, sharp edges, or a premium unboxing requirement that needs structure, then yes, boxes may still win. Packaging is not religion. It’s math. In one Atlanta fulfillment center, switching from a 12 x 15 mailer to a 10 x 13 size cut dimensional charges on 3,400 monthly shipments without changing the SKU mix.

If you want to compare all packaging formats at the same time, our Custom Packaging Products page is a good starting point, and our Custom Poly Mailers page shows the mailer styles we produce most often.

I also tell buyers to stop ignoring shipping class assumptions. Mailers are lighter, but if the package crosses a carrier’s dimension threshold, the bill changes fast. UPS, FedEx, and USPS all care about measurements, not your feelings. If you are unsure, check current carrier guidance and packaging standards from the ISTA testing framework and general packaging references from the Packaging Institute. A 14 x 19 mailer can trigger a very different rate than a 10 x 13 bag, even when both weigh under 8 ounces.

Poly Mailers Bulk Order Options: Stock, Printed, and Custom

A poly mailers bulk order usually falls into three buckets: stock plain mailers, printed stock mailers, and fully custom mailers. The right choice depends on cash flow, branding goals, and how fast you need the order. I’ve had founders call me wanting “premium” before they even had repeat packaging data. Fine. But if the team is still testing product-market fit, plain stock mailers are often the smarter move. Save the budget for inventory and customer acquisition. Packaging can wait until the unit economics are proven, especially if you are still moving fewer than 1,000 parcels a month from a warehouse in Dallas or Chicago.

Stock mailers are the fastest and cheapest. Usually white, black, or gray, with a self-seal strip. They are made for speed, not storytelling. For a poly mailers bulk order where margin is tight, stock mailers keep cash tied up in the right place: your product, not your bag art. I’ve seen startups blow $1,500 on custom print before they knew whether the SKU would sell. That’s not branding. That’s expensive optimism. And if I sound a little blunt here, it’s because I’ve watched that exact money disappear and then heard the sighs afterward. A plain 14 x 17 mailer in a 5,000-piece run can arrive in 12 to 15 business days from proof approval if the supplier already has the film in stock.

Printed mailers sit in the middle. You can get one-color logo print, 2-color branding, or a simple pattern that looks more intentional than plain stock without pushing you into full custom tooling. For many e-commerce brands, this is the sweet spot. A poly mailers bulk order with one-color logo print can add only a small premium if the artwork is clean and the run volume is high enough. If your logo is just a black mark on a white bag, there is no need to act like it belongs on a luxury perfume carton. I’ve seen one-color printed mailers in 10,000-piece lots stay around $0.16 to $0.19 per unit ex-factory when produced near Shenzhen with standard 2.5 mil film.

Custom mailers are where you choose the exact size, thickness, film finish, and print style. This is the route for stronger brand presentation, especially when you want inside-out branding, metallic finishes, or a full-coverage design that customers see the moment they open the parcel. For a poly mailers bulk order, custom production makes sense when your volume is stable and your SKUs are standardized. A custom run with a matte finish and 3 mil co-extruded film may take 12 to 20 business days after proof approval, plus 4 to 12 days for ocean or regional trucking, depending on whether it ships from Ningbo, Shenzhen, or Ho Chi Minh City.

Common mailer styles buyers request

• Self-seal mailers with tamper-evident adhesive
• Opaque black or white mailers for privacy and branding
• Metallic finish mailers for premium presentation
• Gusseted mailers for bulkier soft goods
• Inside-printed mailers for a more polished unboxing moment

Brand use case matters too. Apparel brands use poly mailers because they fold flat and don’t crush soft goods. Beauty brands use them for boxed products that still need privacy and a clean look. Supplements often use them for DTC fulfillment where the outer package needs to stay light. Promotional teams like them because a poly mailers bulk order can standardize packing across campaigns and reduce warehouse confusion. In a 2024 run for a cosmetics distributor in Phoenix, a 3.5 mil matte black mailer cut split shipments by 14% because the packers stopped using three different carton styles.

I had a client in the supplement category who was running seven mailer sizes across ten SKUs. Seven. That is not a system; that is a warehouse tax. We consolidated them into three sizes and set a packing chart. Their pick-and-pack labor dropped by about 11 minutes per 100 orders because the packers stopped hunting for the “right” bag. Small thing. Big noise reduction. On a 20,000-order month, that kind of change can save more than 36 labor hours.

Print choice also changes the buying decision. A poly mailers bulk order with full-color process printing looks better, but it costs more and usually requires tighter artwork control. One-color logo print is the easiest and often the best ROI. Inside-out branding can be fun for premium apparel, but it increases print complexity. I always ask: does the customer actually see this, or are we just entertaining ourselves in a design file? If the answer is “mostly the warehouse team,” the money is probably better spent on stronger adhesive or a tighter size tolerance.

Option	Best For	Typical Cost Impact	Lead Time
Stock plain mailers	New brands, fast replenishment, tight budgets	Lowest	Fastest
Printed mailers	Brands wanting basic identity without high setup cost	Moderate	Moderate
Fully custom mailers	Stable SKUs, stronger branding, premium presentation	Highest	Longest

For buyers who already run steady shipping volume, a poly mailers bulk order can be standardized across SKU families. That means fewer size decisions, fewer packing errors, and lower storage headaches. Honestly, I think this is one of the most underrated savings levers in packaging. People obsess over print color and forget labor, which is a bit like polishing the car while the engine is throwing sparks. A three-size system can be easier to train on than a seven-size maze, especially in warehouses in Texas, New Jersey, or Southern California where turnover can be high.

If you are comparing distribution models, our Wholesale Programs can help if you need recurring replenishment instead of one-off ordering.

Poly Mailers Bulk Order Specifications to Check Before You Buy

A poly mailers bulk order should never be placed off a blurry product photo and a one-line quote. I’ve seen buyers approve a sample that looked fine on a desk, then discover the production bag was 15mm shorter in width tolerance and too tight for their folded hoodie. That is how returns and repackaging creep in. Ask for real specs. Not vibes. Not “it should be fine.” Real specs. If the supplier is in Guangzhou, Dongguan, or Wenzhou, they should still be able to give you a proper data sheet in millimeters, mils, and carton counts.

The main specs I check first are film thickness, bag dimensions, seal strength, opacity, and water resistance. Thickness is usually listed in microns or mil. As a rough reference, 2.5 mil may work for soft apparel, while heavier items or products with more edge stress may justify 3 mil or more. But thicker does not automatically mean better. It means heavier, more material, and a higher price. If the bag is too stiff, it may actually waste money without improving performance enough to matter. For a 40,000-piece poly mailers bulk order, a jump from 2.5 mil to 3.5 mil can add enough resin cost to change your landed price by several hundred dollars.

Here is the spec sheet data I want before any poly mailers bulk order is approved:

• Material type such as LDPE or co-extruded film
• Thickness in mil or microns
• Flat dimensions and gusset depth, if any
• Print area and ink coverage percentage
• Adhesive type and seal length
• Dimensional tolerance
• Carton pack quantity
• Outer carton dimensions for freight planning

Adhesive is a bigger deal than most buyers think. Weak adhesive causes returns because bags pop open in transit. I once inspected a run where the seal strip looked fine, but the liner release was too easy and the bond failed under a hot warehouse condition. We caught it before the customer did. That saved a headache and probably a few red faces too. A poly mailers bulk order needs seal performance that stays consistent through temperature swings and handling abuse. In a July test at a facility near Savannah, a low-grade strip failed after 90 minutes at 38°C, while a higher-spec adhesive held through a 24-hour room-temperature cycle.

Opacity matters if you’re shipping anything that should not be visible through the film. Black-out layers are common, but not all black mailers are equal. I’ve seen “opaque” bags that still showed outlines under bright warehouse light. Not ideal if you sell premium clothing or confidential kits. Ask for an actual sample and hold it under a strong light. Cheap surprises are still surprises. A true opaque bag often uses a black inner layer with a white outer layer, or a co-extruded structure that blocks silhouettes better than a single-layer tinted film.

Shipping compatibility is another trap. USPS, UPS, and FedEx all have dimensional rules, and the wrong size can push a shipment into a more expensive category. If the mailer is oversized, even by a little, the total bill can rise. A poly mailers bulk order should match the product after folding, not the product in a fantasy world where every sweater compresses perfectly. In practical terms, a 12 x 15 bag for a 9 x 12 garment can be fine; a 15 x 20 bag for the same item may be money you never needed to spend.

I also want production proofs. A digital proof shows artwork placement, but a physical sample shows the real seal, texture, and print tone. For higher-volume poly mailers bulk order projects, I strongly recommend either a pre-production sample or a pilot run. If your brand color is a specific Pantone, say so. If you want CMYK, define the range you will accept. Ambiguity is how people end up arguing with a factory over “close enough” green. A proper sample from Shenzhen or Suzhou can save you from 10,000 bad impressions later.

For environmental claims, be careful. Some mailers contain recycled content; some are recyclable in limited local streams. Don’t slap a green message on the bag unless you can back it up. The EPA has useful guidance on waste and materials claims, and I’d rather buyers stay accurate than clever. If a supplier says a bag contains 30% post-consumer recycled content, ask for the supporting documentation before you print it on the carton.

My rule is simple: if the supplier cannot give you a coherent spec sheet with thickness, tolerance, adhesive details, and carton pack, do not place a poly mailers bulk order yet. That’s not being picky. That’s avoiding expensive nonsense. A spec sheet with 350gsm C1S artboard notes for inserts, 3 mil film callouts, and carton dimensions in centimeters is far more useful than a sales sheet with three adjectives and a smiley face.

Poly Mailers Bulk Order Pricing and MOQ Breakdown

Pricing for a poly mailers bulk order usually falls into three lanes: plain stock, low-MOQ printed, and fully custom bulk runs. Plain stock is cheapest because the factory already has the film, size, and color set up. Low-MOQ printed mailers cost more per unit because the press setup gets spread over fewer pieces. Fully custom bulk runs give you the best unit economics once you hit the right volume, but the setup can be annoying if your order is too small. That’s the tradeoff. No factory is donating tooling because your logo is pretty. In Qingdao or Ningbo, the economics are just as cold as they are anywhere else.

Here is a realistic pricing framework I use when I’m quoting clients for a poly mailers bulk order:

• Plain stock mailers: about $0.08 to $0.16 per unit depending on size and thickness
• Low-MOQ printed mailers: about $0.14 to $0.28 per unit
• Fully custom bulk runs: about $0.10 to $0.24 per unit at higher quantities, before freight

Those are broad ranges, not promises. Size changes everything. A 6 x 9 mailer does not price like a 14 x 19 mailer. Thickness changes everything. A 2.5 mil bag does not price like a 4 mil bag. Print coverage changes everything. One-color corner logos are much cheaper than full-coverage art. If your supplier gives you one flat number without asking about specs, they are either guessing or playing games. A 5,000-piece quote for a plain white 10 x 13 bag might come in at $0.15 per unit, while a 20,000-piece run could fall closer to $0.11 depending on resin market conditions and freight origin.

The MOQ is another place where buyers get surprised. For a poly mailers bulk order, minimums may look low for stock plain mailers because the product already exists. Custom printed mailers often start higher because the supplier has to cover setup, plates or screens if applicable, and production loss during changeover. In practice, you might see 1,000 units for stock items, 3,000 to 10,000 for simple printed runs, and 10,000-plus for fully custom work. But always ask by size and print method, because both can change the threshold. A 12 x 16 matte mailer in Vietnam may be available at 3,000 units, while a metallic 16 x 20 bag in Shenzhen may need 10,000 before the factory will touch it.

What moves price the most?

1. Size — more film means more cost
2. Thickness — thicker film uses more resin
3. Print colors — more colors usually means more setup and longer press time
4. Ink coverage — large solid areas use more ink and can slow drying
5. Adhesive upgrades — tamper-evident or stronger seals cost more
6. Freight method — ocean, air, truck, or mixed shipping can swing landed cost hard

I once sat through a pricing call where a buyer kept comparing two quotes that looked close on unit price. One was ex-factory. One included cartonization, freight, and duty. By the time we normalized both, the “cheaper” one was $0.031 more per bag. On a poly mailers bulk order of 80,000 pieces, that is $2,480. That is not pocket change. That is someone’s laptop, trade show budget, or a month of ad spend. On a smaller 5,000-piece run, even a $0.02 difference is $100, which can be the difference between a workable launch and a painful one.

Budgeting should include samples, freight, and maybe import duty if the order crosses borders. If plates or screens are required for the print method, include those too. A lot of flexographic and screen setups are modest, but they are not free. And if you need a color match on a specific brand Pantone, a re-run or correction can cost you real money. I have seen corrective reprints erase the savings of the original quote. Painful. Entirely avoidable. A pre-production approval in Hangzhou can save a full container from leaving with the wrong logo tone.

To estimate per-unit cost before requesting a quote, do this:

• Choose the product size first
• Add 10% safety margin for film waste and seal width
• Request pricing at three volumes: 5,000, 10,000, and 20,000+
• Compare delivered pricing, not only ex-factory pricing
• Ask whether freight is consolidated or charged separately

If you are buying repeat packaging, our FAQ section and Wholesale Programs can help you compare pricing structures before you commit to a poly mailers bulk order. I like that process because it cuts the drama. Everyone talks numbers early, which is how it should be.

Poly Mailers Bulk Order Process and Timeline

The actual ordering process for a poly mailers bulk order is straightforward if the buyer is organized. It gets messy when the buyer sends half a logo, no dimensions, and a deadline that was clearly invented in a panic. I’ve seen both. The cleanest orders move through the same steps every time: inquiry, quote, artwork submission, proof approval, production, quality check, packing, and shipping. A competent factory in Shenzhen or Xiamen should be able to describe the path in under five minutes.

Here is the usual flow for a poly mailers bulk order:

1. Send size, quantity, print needs, and ship-to address
2. Receive a quote based on material and volume
3. Submit artwork in AI, PDF, or print-ready vector format
4. Review digital proof or sample
5. Approve production
6. Factory runs QC, cartons, and palletizes
7. Freight is booked and tracking is shared

Timelines depend on stock versus custom. A stock poly mailers bulk order can move in roughly 5 to 10 business days if inventory is available and the shipping lane is simple. Custom printed mailers are usually more like 12 to 20 business days after proof approval, sometimes longer if the print is complex or the factory is busy. If you need ocean freight, add transit time. If you need air, add cost. That is not philosophy. That is logistics. In many cases, the clean number to remember is 12 to 15 business days from proof approval for a standard printed run from southern China, then 3 to 7 additional days if you are trucking into a U.S. distribution center.

The biggest delay is often artwork approval, not the factory run. Buyers assume the press is the slow part. Sometimes it is, but usually the real pause is waiting for someone internal to approve the logo placement or confirm a Pantone color. If you are serious about a poly mailers bulk order, get those decisions made before the supplier starts cutting film. I’ve watched a two-day production window turn into a two-week delay because one person said the logo felt “a little too left.” I wish I were kidding. In one case, a client in Austin lost a Friday ship date because three managers had to weigh in on a 6mm margin shift.

Fastest way to keep the process moving: send all of this in one message.

• Exact bag dimensions
• Quantity needed
• Material or thickness preference
• Print file or brand logo
• Delivery location
• Deadline or in-hands date

On the factory side, good QC means checking bag dimensions, seal integrity, print registration, and carton counts before shipment. I’ve watched production teams label cartons by size and color code them for warehouse handling, which sounds boring until you’re loading mixed SKUs and one mislabeled carton ruins an entire pallet. A strong poly mailers bulk order should include clear carton marks and lot identification so issues can be traced quickly if there is ever a problem. A batch code like SH-2025-06 can make a defect audit much easier in Hangzhou, Rotterdam, or Savannah.

Once the shipment leaves the plant, tracking should be shared without you having to chase it three times. If the supplier cannot tell you whether the goods are on a truck, in port, or booked for courier handoff, that is a problem. Communication matters more than fancy sales language. I’ve worked with factories that never missed a promise because they were disciplined about updates. I’ve also worked with factories that were charming right up until the day they vanished for a holiday and left a buyer staring at an empty warehouse. Guess which one I prefer. A simple status update every 48 hours can prevent a lot of noise.

For compliance-minded buyers, testing against ISTA transit methods or referring to common packaging durability standards helps reduce complaints after launch. A poly mailers bulk order is not just about making a bag. It’s about making a bag that survives the trip. If your outer pack is going from Guangzhou to Chicago, then through parcel sortation and into residential delivery, it needs more than good intentions.

Why Order Poly Mailers Bulk From Us

We work like a packaging partner, not a brochure. If you need a poly mailers bulk order, we focus on the things that actually protect your budget: direct factory communication, transparent specs, and pricing that reflects real volume instead of padded middleman margins. I built packaging supply relationships the hard way, standing on factory floors in Shenzhen and Foshan and asking awkward questions about seal testing and scrap rates. That habit still saves clients money.

Here’s what usually helps our buyers:

• Better pricing structure when the volume is consistent
• Direct communication with the production team
• Sample review before the full run
• Artwork checks to catch sizing or bleed issues early
• Shipment coordination so freight timing is not a mystery

One negotiation I remember clearly involved a branded mailer run that looked too expensive on first quote. I asked the factory to separate film cost, print cost, and packing cost. Suddenly the picture changed. We trimmed the bag width by 20mm, reduced ink coverage, and adjusted the carton pack. The client saved about $1,100 across the run. No drama. Just better specs and a supplier willing to explain the math. That is the kind of support I think a poly mailers bulk order should get. On a 15,000-piece order, that kind of saving can cover sampling, freight, and a decent chunk of launch advertising.

We also keep the process practical for brands that do not want unnecessary complexity. If you need plain stock bags, we’ll tell you that. If you need full custom branding, we’ll say what it really costs and what print method fits the volume. If your deadline is tight, we’ll tell you whether stock inventory or a simpler print is the only sane move. I prefer honest constraints over fake enthusiasm. Saves everyone time. A buyer in Toronto once needed bags in 9 business days; the only realistic path was stock white mailers from a regional warehouse, not a custom print run across the Pacific.

Documented specs matter because they lower risk. Production confirmation matters because it prevents misunderstandings. Clear lead times matter because nobody wants to discover a delay after their launch email is already scheduled. A poly mailers bulk order should be boring in the best way: repeatable, traceable, and priced with no hidden nonsense. If a supplier can quote, sample, and ship without changing the story every two emails, that is usually a strong sign.

If you are expanding packaging across categories, our Custom Poly Mailers page shows the style range, and our Custom Packaging Products page helps you compare with other packaging options.

“The best packaging order is the one that arrives on time, seals properly, and does not force a second round of corrections.” — That’s what I tell buyers after too many factory visits to count.

Poly Mailers Bulk Order Next Steps

If you’re ready to place a poly mailers bulk order, the fastest path is to send the specs in one message. I mean all of them: dimensions, thickness target, quantity, print needs, and delivery location. Half-finished requests slow everything down. A complete request gets a real quote faster, and a real quote gets you to the point where someone can actually make the thing. If you can also include a target ship date and the city, such as Atlanta, Miami, or Seattle, you’ll usually get a tighter freight estimate too.

Before you commit, decide whether you want stock, printed, or fully custom. If budget is tight and branding is not the priority yet, stock is the sensible move. If your brand needs visible identity but you still want to control spend, printed is usually the balance point. If volume is stable and presentation matters, custom can make sense. A poly mailers bulk order should match the stage of the business, not somebody’s Pinterest board. A 2,000-piece startup order and a 50,000-piece replenishment run should not be priced or spec’d the same way.

Use this checklist before approving the final order:

• Have you confirmed the exact size after product folding?
• Did you request samples if thickness or seal strength is uncertain?
• Do you know the MOQ by size and print method?
• Is the quote delivered pricing, not just ex-factory pricing?
• Has the timeline been confirmed in writing?

If you are comparing options, ask for at least two pricing points and one sample before you lock it in. I’ve seen buyers skip the sample because they wanted to save $25, then spend $250 correcting a print or replacing a weak seal. That is the kind of thrift that turns expensive very quickly. A poly mailers bulk order is one of those purchases where a little discipline up front prevents a lot of nonsense later. A 500-piece sample impression is usually cheaper than finding out your 10,000-piece run in the wrong opacity shows every folded hem inside the bag.

Send the specs and artwork together. That is the fastest way to lock pricing, confirm feasibility, and move your order forward without wasting a week on back-and-forth messages. If you need help choosing the right packaging format, start with the simplest thing that ships well. Your margins will thank you. And if your packaging needs grow later, you can always move from stock white mailers to a custom 3 mil printed run from Shenzhen, Ningbo, or Dongguan once your monthly volume justifies it.
