Oxygen-absorbing multi-layer film and method for preparing same |
摘要 |
An oxygen absorbing multi-layer film having a smooth surface is provided. The multi-layer film includes an oxygen permeating resin layer, a deoxidizing resin layer containing a particulate absorbing composition, a smoothing layer and a gas barrier layer. The oxygen absorbing multi-layer film is produced by extruding a resin composition containing a particulate oxygen absorbing composition to form a deoxidizing resin layer on a surface of a polyolefin resin forming a smoothing layer as a substrate for lamination, laminating an oxygen-permeating resin layer to the upper surface of the deoxidizing resin layer and laminating a gas barrier material on a lower surface of the smoothing layer. The multi-layer film has no protrusions through the film surface and has excellent heat-sealing and handling properties.
