Bag for storage and removal of oxygen

摘要

A flexible bag for food storage includes an oxygen remover, a water impermeable membrane, a frangible seal, and walls having low oxygen transmission. The wall comprises two facing sheets, and at least one sheet is a multilayer sheet having an inner layer of polymer enabling the facing sheets to be joined by melt sealing at less than 95° C. The bag may be sealed at location other than the frangible seal. A machine-readable image (e.g. QR code) may direct a computer or phone to a video on the Internet that shows re-sealing the bag at a location separate from the frangible seal to isolate the storage region from air surrounding the bag.

1. A flexible bag for food storage comprises two facing sheets forming the walls of a bag, each of the facing sheets having an oxygen transmission rate at 25° C. of less than 10 cm3/m2/day, and at least one of the facing sheets is a multilayer sheet having an inner layer of polymer enabling the facing sheets to be joined by melt sealing at less than 95° C.; wherein the two facing sheets are joined together along three adjacent edges to form a rectangular pouch, and the pouch is separated into inner and outer sections by a frangible seal affixing the two facing sheets; the inner section contains an oxygen remover, an optional oxygen indicator, a storage region with fillable volume between 0.35 L and 8.5 L, and a water impermeable membrane with oxygen transmission rate at 25° C. of more than 2000 cm3/m2/day separates the oxygen remover from the storage region.
