BAGS CONTAINING OXYGEN ABSORBENT

摘要

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.
