Abstract:
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 cm 3 /m 2 /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 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 cm 3 /m 2 /day separates the oxygen remover from the storage region wherein a first membrane retards oxygen passage between the oxygen remover and the storage region, a second membrane retards oxygen passage between the oxygen indicator and the storage region, and the oxygen permeability of the first membrane is less than the oxygen permeability of the second membrane.
