The oxygen absorbent is mainly used for storage of foodstuff, particularly liquid or semi-liquid foodstuff.

Oxygen absorbent packaging

An oxygen absorbent package comprising a rectangular nonwoven fabric sheet, a rectangular perforated film or nonwoven fabric sheet having a lower softening point than sheet, a rectangular microporous film or nonwoven fabric sheet having a higher softening point than film or sheet, and an oxygen absorbent, the three layers being heat sealed on the four sides is disclosed. The oxygen absorbent package is mainly used for storage of foodstuff, particularly liquid or semiliquid foodstuff.

At least part of the material constituting the bag in which an oxygen absorbent is sealed is composed of a laminated sheet in which a gas permeable sheet is laminated to one or both sides of a microporous film to provide a lamination the two outside layers of which have different softening points, the layer having a lower softening point constituting the inner surface of the bag is disclosed. The bag of this invention can be produced at a high speed by using an ordinary heat-seal machine.
