Simple. Flat. Perfectly Protected.
Three-side-seal flat mylar pouches with custom printing and multi-layer barrier protection.
Flat mylar bags are three-side-seal pouches: sealed on the left, right and bottom, open at the top for filling, then heat-sealed shut. With no gusset they lie flat, which makes them the most economical mylar format for samples, single servings, sachet-style packs, gummies, powders and flat items.
Also called: 3-side seal bags, three-side seal pouches, lay-flat pouches, flat pouches, heat-seal flat bags, flat barrier bags, sample mylar bags.
Custom printed flat mylar bags with three-side-seal construction for cost-effective, space-efficient packaging. These flat pouches lie completely flat for easy shipping, automated filling, and compact storage. Multi-layer barrier protection keeps contents fresh while full-surface custom printing delivers complete brand messaging.
Flat mylar bags are the workhorse of flexible packaging — simple, cost-effective, and incredibly versatile. Built with a three-side-seal construction, these completely flat pouches are ideal for products that do not require a stand-up format, including sachets, sample packs, single-serve portions, jerky, spices, and long-term food storage.
The multi-layer laminated construction combines PET, aluminum or metallized film, and PE to create a powerful barrier against moisture, oxygen, light, and odor. Whether you need small 2x3 inch sample sachets or large 16x18 inch bulk storage bags, flat mylar pouches deliver reliable protection at the lowest cost per unit in the mylar family.
Every flat bag can be fully custom printed on one or both sides with CMYK or Pantone colors. Add tear notches for easy opening, resealable zippers for reuse, or hang holes for retail display. Available in metallized silver, kraft, matte black, matte white, clear, holographic, and heavy-duty aluminum foil laminate materials.

Flat mylar bags are the format brands order in the largest quantities: sample programs, single-serve packs and trial sizes. There is no gusset or bottom panel, so each bag uses little film, and the price per bag falls quickly in bulk. Wholesale buyers often pair a flat 3-side seal sample bag with a full-size stand-up pouch in the same artwork.
Yes. Cubit makes flat mylar bags to order in its own factory and quotes them factory-direct, so wholesale buyers deal with the manufacturer, not a reseller. Send your size, quantity and artwork, and we price your exact specification.
Price is per bag and depends on size, film, print colors, closures and quantity. The bigger the run, the lower the price per bag, because setup is spread over more bags. List several run sizes in your request, for example 5,000, 10,000 and 25,000, and we quote each one.
Yes. Large runs are where our factory is most efficient, and we quote orders of 100,000 bags and more. Tell us in your request if you need the order delivered in stages or repeated on a schedule.
