What fits, honestly
The 10 × 13 is a usable 9.5 × 12 in once the seal flap is closed. Fold to that, not to the bag.
| A folded tee or two | Comfortably |
|---|---|
| Leggings, a light dress, a scarf | Yes |
| A hoodie | Tight; move to 12 × 15.5 |
| Shoes in a box | No — a box needs a box |
Film thickness for the size
At 10 × 13 a 60 micron co-extruded film is strong enough for a garment; 75–80 micron for anything with a corner — a boxed accessory, a book — that could puncture. Recycled-content film at the same gauge is as strong and a shade greyer. Our ecommerce poly mailers in every size cover the other formats and the compostable film.
The three strips
Fashion brands specify all three; a brand with no returns keeps the first only.
- A permanent self-seal at the top — closes once, tamper-evident.
- A returns strip below it — the customer reseals the same bag to send back.
- A tear strip — opens the bag cleanly without scissors.
Printing the most-used bag
Because the 10 × 13 is the bag a customer sees most often, it carries the brand: a full-coverage color, a pattern, a logo, a line about the brand. Flexo up to eight colors on the outside, an inside print if wanted, and a clear panel for the label. The design is set on the mailer template with the seal and the panel marked.
A full-coverage dark print shows scuffs from the sorting machinery. A pattern or a mid-tone hides them.
Order sizes and the cost of a mailer
A hundred mailers is a trial; a thousand is a small brand's season. Printed 10 × 13 mailers cost a few cents each at volume, and they ship in cases of 500 or 1,000 that sit flat under a bench.

On every job
- Print process
- Flexo in up to ten colors on the outer film, or digital for short runs and changing artwork.
- Color
- A white underprint carries normal color on metallised or clear film. Without it, every color takes on what is beneath it.
- Tolerance
- Bag width plus or minus 2 mm, length plus or minus 3 mm. Film stretches, so a barcode is verified on a filled bag.
- Tooling
- Print plates or cylinders per design, kept. There is no cutting die — the bag is formed and sealed rather than cut.
- Food contact
- A food-grade sealing layer against the product, with the inks trapped between layers rather than on the food face.
- Sustainability
- Mono-material PE or PP where the shelf life allows, which recycles as a soft plastic. A foil laminate does not.
- Artwork
- Vector PDF or AI, 3 mm bleed, 4 mm safe area, fonts outlined. We check every file and send a proof before press.
- Dieline
- Supplied free with the quote, before you commit. Yours whether or not you order.
- Sample
- A plain unprinted sample at the finished size on request, for fit and construction.
- Reorders
- Skip the tooling and go straight to press at a lower unit price.
- Lead time
- Quoted with the price against your fill date rather than promised before we have seen the spec.
- Markets
- United States, United Kingdom, Canada, Australia — priced in the delivery currency, freight included.
Boards and films we build 10x13 poly mailers on
A flexible pack is a stack of films laminated together, and the middle layer is the barrier. The structure is chosen from the shelf life you need and what you want to be able to say about recycling.
PET / PE
A printable outer and a sealing inner. Moisture barrier, modest oxygen barrier. The everyday laminate for dry goods sold quickly.
2-ply, 70–110 micronPET / AL / PE
Aluminum foil in the middle: the strongest barrier against light, oxygen and moisture. Coffee, supplements, anything with a long shelf life.
3-ply, 90–130 micronMetallised PET
A vapour-deposited metal layer. Bright, lighter and cheaper than foil, with a weaker barrier. Most silver and gold bags are this.
2–3 plyMono-material PE
Every layer polyethylene, so the bag recycles as a soft plastic. Less barrier and a slightly softer hand; the sustainable choice where shelf life allows.
100–130 micronMono-material PP
Stiffer and clearer than PE, with better heat resistance. Suits a stand-up pouch that has to hold its shape on a shelf.
90–120 micronKraft-paper laminate
A paper outer over a film barrier. The natural look with a real barrier behind it; the paper takes only a matte, flat print.
Paper 60–80gsm + filmCompostable film
PLA and cellulose structures certified for industrial compost. Lower barrier, higher cost, and no home-compost claim unless the certificate says so.
60–90 micronLDPE mailer film
Co-extruded opaque film for shipping bags: tear- and puncture-resistant, weatherproof, and recyclable where soft plastics are collected.
60–80 micronNot sure which? Say what goes in it and where it is sold — the material follows from that. Our notes on recycled, recyclable and compostable cover which claims each stock can honestly carry.
- 01
Send what you have
A dimension, a photograph beside a ruler, or the product itself. No technical drawing needed — that part is ours.
- 02
We quote and draw
A price, a dieline and a date come back together. If a different build would suit the product better, that is in the reply too.
- 03
Approve the dieline
The flat drawing is yours to check: which panel is the front, where the folds fall, how deep the cavity really is.
- 04
Artwork on the dieline
You place your design on the flat we sent, or we place it for you, and you see a proof before anything goes to press.
- 05
A sample if you want one
A plain unprinted sample at the finished size shows fit and construction — the things a drawing cannot.
- 06
Cut, printed, shipped
The die is cut once and kept, so every reorder skips the tooling and goes straight to press at a lower unit price.
Format
Vector PDF or AI where possible. Raster artwork at 300dpi at final size, in CMYK.
Bleed
3 mm past every trim line, so a fraction of drift on the cutter never leaves a white edge.
Safe area
Keep type and anything important 4 mm inside the cut and away from every fold.
Color
Convert to CMYK before sending. Uncoated stock prints lighter; a spot color is the only exact match.
Fonts
Outline them or supply the files. A missing font substitutes silently and the proof will not match.
Barcodes
On a light, matte, unvarnished patch with the quiet zone clear — a code on gloss fails the scanner.
Not set up that way? Send it anyway — fixing a file is a short conversation, and we check every one before press. Our guide to preparing print files covers each point.
Film is finished in the lacquer and the ink, not with a laminate.
Matte lacquer
A soft, non-reflective face. Hides handling marks and the most-used finish on a premium pouch.
Gloss lacquer
Wet-looking color. Reads cheaper on some categories and exactly right on confectionery.
Spot matte on gloss
A matte shape on a gloss field, or the reverse. The film equivalent of spot UV.
Metallised effects
Print over the metal layer so a color picks up the shimmer, or lay white under it for a normal color.
Registered emboss
A raised texture pressed into the film. Rare, expensive, and unmistakable in the hand.
Kraft-paper face
A paper outer laminated to the barrier. Matte and flat by nature; no varnish needed.

Sizing a pouch by what goes in it, not by a bag size: 10x13 poly mailers
Film packs are specified by fill, not by dimensions. Two products of the same weight can need very different bags, because density decides volume — whole coffee beans take far more room than the same weight of powder.
- Fill weight and density
- Give us both, or send the product. We size from the volume it actually occupies, settled.
- Lay-flat width
- Half the circumference of the finished bag. It is the number a converter works to, and we calculate it from your product.
- Headspace
- Enough film above the fill to seal cleanly and for the bag to stand. Too little and the seal traps product; too much and the pack looks underfilled.
- Gusset
- Bottom gusset depth sets how the bag stands; side gussets add volume without width. Both are chosen from the shelf, not the fill.
- Seal width
- 5–8 mm. Wider on liquids and creams, which contaminate a seal, and on anything that will be posted.
- Sample fill
- A plain bag at the finished size, filled from your line, is the only reliable check before print.
Not sure your numbers are right? Send the product dimensions rather than the box dimensions and we work the box out — the full method is in our guide to measuring for a box.

What fits in a 10 × 13 mailer?
A folded tee or two, leggings, a light dress, small accessories. A hoodie is tight and wants the next size up.
What is the usable size?
About 9.5 × 12 inches once the flap is sealed. Fold to that.
How thick is the film?
60 micron for garments, 75–80 micron for anything with a corner that could puncture.
Can I have a returns strip?
Yes, a second seal strip below the first so the customer reseals the same bag.
Can it be printed?
Yes, up to eight colors flexo, full coverage or a logo, with a clear panel for the label.
What is the minimum order?
100 bags.
Is it recyclable?
As soft plastic where collected. A recycled-content film is available at the same strength.
Is it waterproof?
Yes, enough for a doorstep in rain.
Will the print scuff?
A dark full-coverage print can show scuffs from sorting machines. A pattern or a mid-tone hides them.
Can the inside be printed?
Yes, a message seen when the bag is opened.
How are they packed?
Flat in cases of 500 or 1,000.
Do you ship outside the US?
Yes, to the United States, United Kingdom, Canada and Australia, quoted in the delivery currency.
