Title:
LAMINATED FILM AND PACKAGE
Document Type and Number:
WIPO Patent Application WO/2015/146829
Kind Code:
A1
Abstract:
Provided is an oxygen-absorbent laminated film that exhibits better deodorizing properties. This laminated film (100) has an oxygen absorption layer (150) that absorbs oxygen, and an odor-retaining seal layer (170) that is permeable to oxygen, but blocks an odorant substance emitted from the oxygen absorption layer (150). In so doing, the odorant substance produced by the oxygen absorption layer is effectively blocked by the odor-retaining seal layer, whereby release of the odorant substance through the odor-retaining seal layer can be effectively minimized. The odor-retaining seal layer (170) is preferably at least a polyester and/or a polycarbonate. The odorant substance may be at least an aldehyde and/or an acid.
