Flat Pouches & Sachets

Flat pouches: slim packaging for slim products

Not every product needs to stand up on a shelf. A face mask sample, a single serving of coffee, a sheet of stickers, a powder sachet: these are thin, flat things, and forcing them into a stand-up bag with a gusset wastes material and looks oversized. A flat pouch keeps slim products slim. It lies flat for mailing, stacks neatly in a display, and uses less film than any standup format.

A flat pouch is a sealed package made from two layers of barrier film, heat-sealed on the edges, with no bottom gusset to make it stand. That simplicity is the appeal: it is the lightest, lowest-cost flexible format, ideal for samples, single-serve portions, and anything thin enough not to need to stand on its own.

What goes in a flat pouch, and who uses them

Flat pouches and sachets are the workhorses of sampling and single-serve. We print custom flat pouches for:

• Cosmetics and skincare samples: serums, masks, creams
• Single-serve food and drink: coffee, drink mix, condiments, spices
• Supplements and powders in single doses
• Pet treats and sample sizes
• Stickers, cards, and slim retail goods
• Seeds, hardware, and small parts

The format shines for anything a brand wants to hand out, mail flat, or sell in volume at a low unit cost. Sampling programs in particular run on flat sachets, because they are cheap to fill and cheap to ship.

Barrier film construction and seals

Flat pouches are built from laminated film, often a mylar or foil-based structure, chosen for its barrier properties. The barrier is what keeps oxygen, moisture, and light out, which matters for coffee freshness, supplement stability, and anything that degrades on contact with air. A foil layer gives the strongest barrier and full light blocking; clear or metallized films trade some barrier for a window onto the product.

The seal pattern defines the pouch. A 3-side seal pouch is sealed on three edges with the fourth a fold, the simplest construction. A 2-side seal (a fin or pillow style) seals top and bottom. Both lie flat. We add a tear notch so customers open it cleanly without scissors, and a resealable zipper is available when the contents get used more than once. Heat-sealing is what closes the pouch around the product on your fill line or ours.

Sizes and how to choose

Size a flat pouch to the product plus the seal margin, with enough film around the contents for a clean, reliable heat seal. Too tight and the seal runs through the product; too generous and you waste film and the pouch looks half-empty. Sachet sizes run small for single-serve and samples, up through larger flat pouches for slim retail products, with custom sizes cut to your fill volume.

Decide on the barrier first, because it drives the film. A coffee sample needs full foil barrier; a sticker pack needs almost none. Then choose whether you need a tear notch (almost always yes) and a resealable zip (only for multi-use contents). Tell us the product, the fill weight, and the shelf life you need, and we will spec the film.

Printing and finishes

Flat pouches print full-color CMYK across the film, and because the surface is flat, the print sits clean and even with no gusset folds to interrupt the artwork. That makes them excellent little billboards for a sample, where the pouch is often the only branding a prospective customer sees before they try the product.

Finishes follow the film: matte, gloss, and kraft-look options. Matte reads premium and modern, gloss makes color and product imagery pop, and a kraft or natural look suits organic and artisanal brands. A clear window can be left in the print so the product shows through. Foil films give a bright metallic base that needs no added finish to look premium.

Minimum order, turnaround, and ordering

Minimum order is 30 pouches, low enough to prototype a sample or test a single-serve SKU before scaling to the large volumes sampling usually demands. Turnaround runs about 10 days from approved artwork. Every order includes a proof so you can check the film, seal type, tear notch, and print before the run. To order, start a quote with your product, fill weight, required barrier, and whether you need a notch or a zip.

Sustainability

Traditional barrier pouches use mixed-material laminates that are hard to recycle, and that is the honest trade-off for the freshness they provide. Where the contents allow, we offer recyclable mono-material and compostable film options that keep most of the barrier while improving end-of-life. For sampling, the smaller material footprint of a flat pouch versus a stand-up bag is itself a win. Tell us your priorities and we will recommend the most recyclable film that still protects the product.

Frequently asked questions

What is a flat pouch? A slim, sealed package made from two layers of barrier film with no bottom gusset, so it lies flat. It is used for samples, single-serve portions, and thin products.

Can I get custom printed flat pouches with my branding? Yes. Flat pouches print full-color CMYK across the whole surface, and the flat face makes them strong little billboards for sampling.

Do flat pouches keep contents fresh? Yes, when built with a barrier film. A foil layer blocks oxygen, moisture, and light, which protects coffee, supplements, and anything that degrades in air.

Can a flat pouch be resealable? Yes. We add a resealable zipper when the contents get used more than once. For true single-serve, a tear notch alone is usually enough.

What is the difference between a flat pouch and a flat-bottom pouch? A flat pouch lies flat with no gusset. A flat-bottom pouch has a folded base that lets it stand upright, which suits coffee and bulkier dry goods rather than slim samples.
