High Barrier Frozen Bag For Food Packaging

This frozen food bag is built from a 140 micron PET/PE laminate. The PET outer layer holds print and resists scuffing; the PE inner layer seals through frost and gives a moisture barrier. The thickness keeps the pack rigid at -18°C and protects against freezer burn during storage and transport. It is available as a flat bottom bag, side gusset bag or stand up pouch.

Filling lines for frozen product usually run at low temperatures, so the seal window matters. PE seals at lower temperatures than foil laminates, which helps when the product is cold. A zipper or slider works on stand up pouches for resealable frozen fruit or vegetables. A window is possible but adds cost and reduces barrier area; use it only if product visibility drives the sale. A one-way valve is not typical here because frozen foods do not degas. For recyclable mono-PE structures, expect a lower oxygen barrier than PET/AL/PE; choose mono-PE when the frozen product is not oxygen-sensitive, and keep foil laminates for longer shelf life.
