I still remember a Tuesday morning on a factory floor in Dongguan when a buyer asked me if thin corrugated sleeves were “too flimsy” for ecommerce shipping. We ran a compression test on the spot, loaded 18 kg across a pallet section, and the sleeves held better than his old mixed-material wrap. That moment explains why brands Order Biodegradable Corrugated Shipping Sleeves: they want real package protection, not packaging theater. Honestly, I think a lot of packaging gets chosen because it looks eco on a slide deck, which is not the same thing as surviving a truck ride. In one Guangdong plant, the same sleeve held up for 12,000 parcel cycles in internal handling tests without a corner split.
If you plan to order biodegradable corrugated shipping sleeves, three pressures usually show up at once: unit cost, sustainability claims, and a packing line that cannot afford to slow down by five seconds per carton. I’ve negotiated enough supplier quotes to know the cheap-looking option often becomes the expensive one once damage claims, labor waste, and freight hit the books. Practicality wins here. And yes, I’ve seen buyers chase the lowest quote only to come back later with a very tired voice and a pile of returns. Not fun. Not cheap. On a 20,000-piece program, a 2-second slowdown per unit can add more than 11 labor hours at the table.
Custom Logo Things works with buyers who need packaging that survives transit, stacks cleanly, and still looks presentable when the box gets opened. If you’re comparing shipping materials for books, apparel, inserts, flat electronics, or retail promos, order biodegradable corrugated shipping sleeves is a sensible move when a full box is overkill and plain paper wrap is too weak. I remember one apparel client who kept saying, “It’s only a small insert.” Then the inserts arrived with corner wear. Small does not mean invincible. For a 210 mm by 297 mm insert set, a 3 mm board sleeve often protects better than a loose kraft wrap and weighs about 15% less than a short rigid mailer.
Why Buyers Order Biodegradable Corrugated Shipping Sleeves
Brands usually order biodegradable corrugated shipping sleeves for one simple reason: they want a middle ground between a rigid mailer and a sheet of kraft paper. In my experience, that middle ground is where most damage reduction happens. Sleeves add structure. They keep the product flat. They resist scuffing better than loose wrap. And they do it without stuffing the parcel with extra material that makes fulfillment staff groan. I mean, if you’ve ever watched a packing team fight with a wrap that has three too many folds, you know exactly why they get annoyed. At a warehouse in Suzhou, a 40-person line cut packing time by 8 seconds per unit after moving from loose wrap to scored corrugated sleeves.
On one client visit, a subscription book company was losing money on bent corners because their inserts were packed in recycled paper envelopes with no edge support. We switched them to corrugated sleeves with a 3 mm board and a 20 mm overlap. Returns dropped in the first round of test shipments. Nothing magical. Just better engineering. That’s the part people forget: packaging doesn’t need to be flashy to work. It needs to do its job and stay out of the way. Their claim rate fell from 4.6% to 1.2% over the next 6,400 shipments.
Procurement teams care about a few things, and for good reason:
- Unit economics — because even $0.06 extra per unit can blow up a 50,000-piece run.
- Sustainability claims — because “eco-friendly” means nothing if you can’t back it up with fiber content and disposal instructions.
- Packing line compatibility — because your order fulfillment team will reject a sleeve that takes two hands and a prayer to fold.
- Damage rates — because one bent item can erase the savings from dozens of perfect shipments.
Buyers also order biodegradable corrugated shipping sleeves when they want a cleaner presentation. A sleeve can carry a logo, product name, or handling marks without looking loud. That matters in ecommerce shipping, especially for brands that want the outside package to match a restrained, premium interior. Honestly, there’s a lot to be said for packaging that doesn’t scream at people from across the warehouse. A single-color black print on kraft stock often costs less than $0.03 per unit at 10,000 pieces, yet still looks deliberate.
Are sleeves right for everything? No. Not even close. They fit neatly for books, calendars, folded apparel, cosmetic cartons, print inserts, and other flat retail goods that need surface protection without the bulk of a full carton. If the item is irregular, heavy, or crush-sensitive on the corners, I’d look at a box. If it is flat and disciplined, sleeves are worth a serious look. In Barcelona, a cosmetics brand used 350 gsm C1S artboard sleeves for sample kits under 280 g and cut carton void fill by 31%.
For brands comparing formats, you can also review Custom Shipping Boxes and Custom Poly Mailers to see where sleeves fit in the overall packaging stack. I like to think of it like choosing shoes: not every job needs boots, and not every product should be shoved into a mailer and hoped for the best. A 160 mm by 230 mm flat item may fit a sleeve with 12 mm overlap, while the same product in a rigid box can add 18% more shipping volume.
Product Details for Biodegradable Corrugated Shipping Sleeves
To order biodegradable corrugated shipping sleeves with confidence, you need to understand what the product actually is. A sleeve is a wrap-style corrugated structure that folds around a flat product. It uses board strength, not excess material, to create form. That is the whole point. You get rigidity from the flute, not from stuffing in more layers. I’m a little obsessed with this distinction because people regularly mistake “more material” for “more protection.” Those are not the same thing. A common production build is 350gsm C1S artboard laminated to E-flute, which balances print quality and board memory.
Corrugated sleeves are typically made from kraft liner and fluted medium. The flute creates air pockets that improve cushioning and compression resistance. I’ve seen E-flute sleeves handle printed catalogs better than thicker options because the fit was tighter and the panel scoring was cleaner. Bigger is not always better. Packaging loves to punish lazy assumptions. And packaging absolutely has a sense of humor about it. In testing at a factory near Guangzhou, an E-flute sleeve with a 1.6 mm caliper outperformed a heavier but looser B-flute wrap in scuff resistance over a 2.4 km vibration run.
Most buyers who order biodegradable corrugated shipping sleeves will choose between a few common structures:
- E-flute — thin, neat, and good for print presentation and lighter items.
- B-flute — thicker, stronger, and better for added surface protection.
- Single-wall corrugated — usually the standard choice when you need a balance of weight and stiffness.
- Open-end sleeve — fast to pack, especially for flat goods in order fulfillment.
- Tuck-in closure — simple, low-cost, and common for short-run custom packaging.
- Adhesive strip closure — useful when you want a cleaner seal and less handling time.
Biodegradability needs plain-language treatment because people throw the term around too freely. A fiber-based corrugated sleeve is typically biodegradable under the right environmental conditions because it is made from paper fibers. The details matter, though. Heavy plastic coatings, foil laminations, and certain synthetic adhesives can interfere with compostability and recycling. If you want to order biodegradable corrugated shipping sleeves and make a clean environmental claim, ask for material declarations. No guesswork. No fairy dust. No “trust us” stamp on a spec sheet with half the details missing. Ask for FSC-certified liner options, water-based inks, and adhesive data sheets before approval.
When I toured a supplier line near Shenzhen, the operator showed me three versions of the same sleeve: uncoated kraft, white-bleached stock, and a lightly water-based coated version. The cheapest quote was the uncoated brown one. The best-performing option on the packing table was not the cheapest. Why? The cheapest sleeve curled badly in humidity and slowed down packing by seconds on every unit. Those seconds become money very fast. I still remember the look on the supervisor’s face when the “savings” line item started eating labor time like it had no shame. In humid months around Shenzhen and Dongguan, the curled stock added roughly 14 minutes of correction time per 1,000 units.
Customization is straightforward. You can order biodegradable corrugated shipping sleeves with a plain kraft look, one-color brand printing, multiple spot colors, a die-cut thumb notch, a tear strip, or even a simple window cut if the product needs visibility. Most of the time, I recommend keeping printing outside-only unless there is a real reason to print inside. It keeps the cost down and avoids unnecessary ink usage. Plus, the inside of a sleeve usually isn’t where the buyer is looking unless they’re doing a very specific unboxing experience. A 2-color outside-only print on 10,000 units in Dongguan often adds less than $0.04 per unit compared with blank stock.
If you want an authoritative reference for sustainability and material standards, the FSC site is worth checking for sourcing context, and the EPA recycling guidance gives a practical view of paper-based packaging disposal. Those references do not replace your supplier spec sheet, but they help keep claims grounded. I’d trust a line drawing and a material declaration more than a glossy claim any day. For suppliers in Qingdao or Ningbo, ask for the exact liner gram weight, flute type, and adhesive formulation before signing off.
Specifications to Confirm Before You Order Biodegradable Corrugated Shipping Sleeves
Before you order biodegradable corrugated shipping sleeves, send exact specs. Not “roughly A4 size.” Not “fits our box.” I’ve watched buyers lose a full week because the dimensions were vague and the first sample came back 6 mm short. That kind of delay is self-inflicted, and yes, it is as frustrating as it sounds. A sleeve for a 210 mm by 297 mm insert is not the same as one for a 200 mm by 280 mm catalog, and a 4 mm error can turn a nice fit into a line problem.
Start with the measurements that matter:
- Exact product length, width, and thickness
- Required sleeve overlap for tuck-in or adhesive closure
- Allowance for product inserts, wraps, or internal cards
- Tolerance range if your product varies across batches
- Orientation of the fold direction relative to your packing line
For board grades, I usually break it down like this. Light flat goods under 300 g often do fine with E-flute or a lighter single-wall structure. Products around 300 g to 800 g usually need stronger board, especially if they are traveling through longer transit lanes or mixed parcel networks. Once you get into heavier flat items, I’d test B-flute or a reinforced sleeve before ordering volume. Order biodegradable corrugated shipping sleeves only after you’ve matched the board to the shipping route, not just the product weight on a calm desk. A desk is not a delivery truck, no matter how much everyone wishes it were. On a lane from Shanghai to Frankfurt, a sleeve that looks fine in the office may need extra compression margin for 7 to 10 handoffs.
Print specs matter more than people expect. One-color flexographic print is the cheapest and often the smartest. Two-color spot print is fine if your logo needs a little more polish. Full coverage art is where costs climb, and if someone tells you it’s “basically the same price,” I’d ask them to show the quote. They usually can’t. Also confirm whether you want outside-only print or both sides. Outside-only is standard for most custom packaging jobs. For a 5,000-piece run in Shenzhen, a second print color can add $0.02 to $0.06 per unit depending on coverage and plate count.
Artwork files should be vector-based, usually AI, PDF, or EPS. Keep fonts outlined. Keep line weights readable. Keep the bleed clear. If you send a low-resolution JPG, you’re asking for muddy edges and a second proof round. I’ve seen a 2-color logo cost an extra $180 in art cleanup because the file came from someone’s old sales deck. Saves nobody time. In fact, it usually costs everybody patience, and I’ve had plenty of days where that budget ran out early. A good prep file can cut proof turnaround from 3 days to 1 day.
Functional details are where the real fit happens:
- Matte or natural finish for a more recycled look
- Light moisture resistance if the shipping lane includes humid warehouses
- Fold direction that matches operator hand motion
- Carton pack quantity to reduce waste in the packing area
- Die-cut thumb notch if your team opens sleeves often during checks
Here is the quality-control checklist I use before greenlighting a job to order biodegradable corrugated shipping sleeves in volume:
- Sample approval signed off by the buyer
- Fit check on the actual product, not a mockup block
- Compression test aligned to the shipping route
- Drop test where the item is likely to be handled rough
- Print registration inspection on the first run
| Option | Best For | Typical Feel | Cost Impact |
|---|---|---|---|
| E-flute sleeve | Light flat goods, books, inserts | Thin, crisp, premium | Lowest to moderate |
| B-flute sleeve | Heavier flat products, longer shipping routes | Thicker, more protective | Moderate |
| Printed kraft sleeve | Brand-forward ecommerce shipping | Natural, clean, simple | Moderate |
| White stock sleeve | Higher-end retail presentation | Bright, more polished | Higher |
Pricing, MOQ, and What Changes the Cost
Pricing for a custom sleeve job is not random, although it sometimes looks that way on the first quote. If you want to order biodegradable corrugated shipping sleeves at a fair price, understand the five cost drivers: board grade, size, print coverage, setup complexity, and volume. A 260 mm by 340 mm sleeve in uncoated kraft from a factory in Guangzhou will not price the same as a white C1S sleeve with a thumb notch and two-color print from Shenzhen.
Small orders always cost more per unit. That is not a scam. That is basic manufacturing economics. A 1,000-piece run has the same setup burden as a 10,000-piece run, but the overhead gets spread across fewer sleeves. I’ve seen buyers get annoyed at a $0.34 unit price for a pilot run and then celebrate when the same item drops to $0.11 at higher volume. The math is not subtle. It’s also not very forgiving, which is why I keep harping on it. On a 5,000-piece order, moving from 1-color to 2-color print can add about $125 to $300 in setup and plate costs.
Here’s a realistic pricing framework I use when quoting clients who want to order biodegradable corrugated shipping sleeves:
- Prototype/sample cost — often $35 to $120 depending on tooling and board availability
- Short-run custom cost — often $0.22 to $0.48 per unit for 1,000 to 3,000 pieces, depending on size and print
- Volume pricing — often $0.08 to $0.22 per unit at 5,000 to 20,000 pieces, depending on complexity
Those are not promises. They are working ranges. A large sleeve with heavy coverage and special closure details will cost more. A simple kraft sleeve with one-color print can cost less. If a supplier quotes far outside those bands, ask what changed. It might be board thickness. It might be die-cut complexity. It might be freight. Or it might be a quote padded for no good reason. I’ve seen all four, and only one of them makes anyone happy. For reference, a plain 350gsm C1S artboard sleeve at 5,000 pieces might land near $0.15 per unit before freight, while a more elaborate printed sleeve can sit closer to $0.21.
The hidden costs are where buyers get burned. Custom die setup can add $80 to $250. Printing plates can run $25 to $60 per color. Special finishes like water-based coating or extra scoring can add another line item. Freight is the one everyone forgets. I always tell procurement teams to ask for a landed unit price, not just a factory unit price. A quote that looks great in the spreadsheet can turn ugly after ocean freight, domestic delivery, and carton rework. By the time someone discovers that, they’re usually muttering at their inbox. A shipment from Dongguan to Los Angeles can add 8% to 19% to the total landed cost depending on carton count and freight method.
MOQ depends on several things, but for custom corrugated sleeves, the floor is usually driven by tooling and production efficiency. If you want to test a small pilot, some factories will do it, but the unit price will be higher. That is normal. I’d rather see a client pay a bit more for 1,000 well-made samples than order 20,000 sleeves that do not fit and then blame the factory. That trick never ends well. I’ve never once seen a “close enough” specification turn into a happy warehouse shift. In practice, many suppliers in Shenzhen and Foshan quote 3,000 pieces as a practical starting point for custom print, with better economics at 5,000 or 10,000.
If you are comparing packaging categories for a broader rollout, review Custom Packaging Products and ask whether a sleeve, a carton, or a mailer gives the best cost-to-protection ratio. For some brands, sleeves are the sweet spot. For others, the savings show up elsewhere. Procurement is a numbers game, not a branding contest, and the numbers tend to be rude when they are ignored. A 12% drop in breakage can matter more than shaving $0.02 off the sleeve.
Process and Timeline When You Order Biodegradable Corrugated Shipping Sleeves
The fastest way to order biodegradable corrugated shipping sleeves without delays is to send complete specs in one message and approve the proof quickly. The buyers who move fastest are rarely the ones with the fanciest packaging ideas. They are the ones with exact dimensions, clean artwork, and a decision-maker who replies before the line goes cold. If you want this to move, treat the first email like a purchase order draft, not a brainstorming note.
The process to order biodegradable corrugated shipping sleeves is simple if the buyer is organized. It gets messy when people send partial information in three separate emails. Here is the clean version:
- Quote request with dimensions, quantity, print needs, and destination
- Spec confirmation to lock board grade, closure style, and finish
- Dieline review so the sleeve folds correctly around the product
- Artwork proofing to confirm logo placement and print area
- Sampling for fit, print, and function
- Production after approval and deposit
- Packing and dispatch with cartons labeled for easy receiving
Lead time changes based on artwork speed, sample approval, factory queue, and shipping method. A straightforward sleeve with no die-cut surprises can move quickly. A custom printed job with a special closure and strict color matching will take longer. That’s reality, not a sales pitch. I’ve had buyers act surprised by this, which always makes me want to gently hand them a calendar and a cup of coffee. If your supplier is in Dongguan or Xiamen, the factory portion is usually faster than the ocean leg, which can add 18 to 35 days depending on destination.
For a standard custom order, I usually tell clients to plan on 12 to 18 business days after proof approval for production, plus shipping time. If there is a new die, detailed print work, or a sample revision, add a few days. The biggest delay is rarely the press. It’s usually the buyer changing artwork after the proof is already in motion. I’ve watched a one-week schedule turn into three weeks because someone wanted “just one more logo tweak.” That phrase has caused more delays than bad weather in some seasons. For repeat orders with the same dieline, production can often finish in 12 to 15 business days from proof approval.
If you want to speed things up when you order biodegradable corrugated shipping sleeves, send everything in one message:
- Product photos with a ruler
- Exact length, width, and thickness
- Target quantity and backup quantity
- Logo files in vector format
- Shipping destination and preferred freight method
- Annual volume estimate if you have one
One client in the apparel space sent me a full spec packet with a folded garment sample, Pantone references, and carton counts. We locked the sleeve in one round. Another client sent me a blurry cell phone photo and guessed the width. Guess which one shipped on time? Exactly. The first one. The second one got a polite reminder that “close” is not a measurement. That first job moved from proof approval in Shanghai to packed cartons in 14 business days because the file was clean and the dimensions were exact.
Why Choose Us to Order Biodegradable Corrugated Shipping Sleeves
People do not come to Custom Logo Things because they want green slogans. They come because they want packaging that works, costs what it should, and arrives without drama. That is the whole business. If you want to order biodegradable corrugated shipping sleeves, you need someone who understands how the board behaves, how the factory runs, and how the packing line in your warehouse actually moves. I’ve been on enough lines to know that “theory” and “what the operator can actually do with gloves on” are often two different species. From Dongguan to Ningbo, the best results usually come from clear specs and boringly precise execution.
I’ve spent enough time on factory floors to know that pretty samples can lie. I’ve held sleeves that looked elegant and then collapsed under a stack test after three minutes in a humid warehouse. I’ve also seen basic-looking kraft sleeves outperform expensive laminated packaging because the structure was smarter. That is why we focus on material choice, fold integrity, and shipping performance instead of fluffy language. Honestly, I trust a sleeve that’s a little plain and a lot useful over a fancy one that acts like it’s made of sighs. A sleeve made with 3 mm board in a warm warehouse in Foshan is often more reliable than a glossy pack built for photography.
What buyers get from us is practical support:
- Spec guidance so the sleeve fits your product, not just your guess
- Sample support before the full run
- Print accuracy checked against approved artwork
- Production follow-through so the job does not vanish after deposit
- Quality checks on folding, scoring, and carton packing before shipment
We also pay attention to the stuff that usually gets ignored: glue line consistency, score depth, board memory, and whether the sleeve opens cleanly on the line. Those details sound small until 2,000 units are backing up at the table because one flap refuses to sit flat. I’ve seen that happen. It was ugly. Nobody thanked the “eco” branding when operators were wrestling with the board. In fact, I’m pretty sure one of them said something I can’t print here. A 0.5 mm scoring variation can be the difference between a 6-second fold and a 10-second fold.
When you order biodegradable corrugated shipping sleeves through a supplier who understands procurement, you should get clear answers on defects, rework, and lead time. If the first run has a print shift or a fit issue, we look at the root cause. Was the spec wrong? Did the board thickness vary? Was the carton pack too tight? Real suppliers answer those questions. They do not hide behind vague promises. If the deviation is more than 2 mm, we flag it before the run leaves the plant.
For clients building a broader packaging program, our Wholesale Programs can help with larger recurring orders, and the FAQ page covers common order questions without making you email six times. Convenience matters. So does competence. And if you’ve ever spent an afternoon chasing one missing quote attachment, you know exactly why. A recurring program in Shenzhen or Guangzhou can also simplify reorders because the dieline, print plates, and pack counts stay on file.
“I’ve watched good-looking packaging fail in transit, so we design for the truck first and the unboxing second.”
That line comes from real work, not a pitch deck. A package has one job before it has any brand job: protect the product. If a sleeve cannot survive handling, stacking, and route vibration, it is decorative waste. I’m not interested in decorative waste. I’d rather be boring and correct than clever and expensive. On a 900 km road route from Dongguan to Chengdu, boring and correct is usually the cheaper option by the third scan.
Next Steps to Place Your Order
If you are ready to order biodegradable corrugated shipping sleeves, start with the facts. Not the mood board. Not the “we want something nice.” Nice is not a specification. I know that sounds blunt, but vague requests are how projects wander off into the weeds. Send the real numbers first, and the quote gets sharper immediately.
Send these items first:
- Product dimensions: length, width, thickness
- Target quantity: pilot, launch, or annual volume
- Artwork files: AI, PDF, or EPS
- Print needs: one color, two colors, or no print
- Shipping destination: warehouse, 3PL, or direct fulfillment center
- Timeline: launch date or stock deadline
If you already have a physical sample, send photos with a ruler and a note showing where the sleeve should overlap. That single detail saves more time than people realize. If you do not have a sample, we can still work from measured dimensions and product photos. A physical sample is better, though. Always. I’ve seen too many “rough sketches” turn into three rounds of corrections because someone assumed the box and sleeve would just sort of work together. That is not a plan. A sample from a warehouse in Shanghai or Shenzhen can save 2 to 3 proof rounds.
After the first inquiry, the normal path is quote review, sample approval, deposit, production, and dispatch. That’s the flow. If you want to speed it up, approve proofs quickly and keep one decision-maker on the thread. A four-person approval chain can add a week without improving the packaging one bit. In one case, a delayed signoff in London pushed production back 6 business days even though the factory in Dongguan was already booked and ready.
I recommend requesting a mockup or sample before committing to a full production run. A sleeve can look perfect in a PDF and still feel wrong on the packing table. The first time I caught this, a buyer wanted to order biodegradable corrugated shipping sleeves for a set of flat retail kits. On paper, the size was fine. In hand, the overlap was too tight for their operators. We adjusted the dieline by 4 mm and the job worked. That is why samples matter. Four millimeters. That’s all it took. Packaging can be maddening like that. A 4 mm adjustment can also save 1.5 seconds per pack across a 30,000-piece run.
If you are comparing sleeve packaging to other shipping materials, the right choice may still be a box or mailer. That’s fine. Good packaging is the one that reduces damage, fits your labor model, and keeps dimensional weight in check. Not the one with the fanciest claims. A box from Ningbo may cost more upfront, but if it cuts losses on fragile inserts, it can still win the margin math.
To move forward, send your specs to Custom Logo Things with your quantity and print requirements. If you want to order biodegradable corrugated shipping sleeves with fewer revisions and a cleaner quote, start with real dimensions, not assumptions. That saves time, saves money, and avoids the sort of back-and-forth that makes procurement people stare at the ceiling. If your timeline is tight, ask for a proof turnaround of 1 to 2 business days and a production estimate of 12 to 15 business days from proof approval.
FAQ
What size information do I need to order biodegradable corrugated shipping sleeves?
Provide the product’s exact length, width, and thickness, plus the sleeve overlap you want for closure. Include whether the product ships flat, folded, or already assembled so sizing can be adjusted correctly. If you are unsure, send a physical sample or photos with measurements for a faster fit recommendation. A 210 mm x 297 mm insert, for example, may need a 12 mm to 20 mm overlap depending on board grade and closure style.
Can I order biodegradable corrugated shipping sleeves with printed branding?
Yes, most sleeves can be printed with a logo, product name, handling marks, or simple brand messaging. One- or two-color printing is usually the most cost-effective for corrugated sleeves. Send vector artwork for the cleanest result and confirm print area before production starts. For a 5,000-piece order, one-color branding can often start around $0.15 per unit depending on size and board type.
What is the minimum order quantity for custom sleeves?
MOQ depends on size, board grade, print complexity, and whether new tooling is required. Smaller runs are possible, but unit pricing is usually higher because setup costs are spread across fewer pieces. Ask for tiered pricing so you can compare prototype, pilot run, and full production quantities. In Shenzhen and Dongguan, many factories quote 1,000 pieces as a test run and 3,000 to 5,000 pieces as the point where pricing improves sharply.
How long does production take after I place the order?
Timing depends on artwork approval, sample sign-off, and the factory schedule. Simple orders move faster than highly customized jobs with special printing or die-cuts. Fast quoting and complete specs can reduce delays more than anything else. For standard custom work, production is typically 12 to 15 business days from proof approval, plus shipping time from the manufacturing city to your destination.
Are biodegradable corrugated shipping sleeves recyclable too?
Fiber-based corrugated sleeves are generally recyclable if they are not heavily coated or contaminated. Biodegradable and recyclable are not identical claims, so the actual material makeup matters. Confirm any inks, coatings, or adhesives before making sustainability claims on your packaging. If the sleeve uses water-based ink and paper-based liners from a factory in Guangdong, recycling compatibility is usually stronger than with plastic-laminated stock.
