ABSTRACT:
Apparatus for storing and dispersing food preservatives in a closed food container. The apparatus includes an absorbent strip sandwiched between two layers of non-woven fabric to form a non-woven fabric combination. This combination is then placed between two layers of plastic film in a lattice network, which is then placed between plastic cover layers. The plastic cover layers are sealed or left opened along their edges allowing the absorbent's gas emission rate to be quantitatively controlled and regulated by means of prearranged perforations and selective opening of the sides and faces of the plastic cover layers.
