A method for producing a sterilized oxygen-absorbing multilayer body is provided. The method may include: irradiating with radiation an oxygen-absorbing multilayer body comprising at least an oxygen-absorbing layer containing a transition metal catalyst and a thermoplastic resin (a) having a tetralin ring as a structural unit and a layer containing a thermoplastic resin (b); and heating the oxygen-absorbing multilayer body which has been irradiated with radiation in the sterilizing step at a temperature of the glass transition temperature of the thermoplastic resin (a) minus 20° C. or more and lower than the glass transition temperature of the thermoplastic resin (a) for 50 hours or more.

A bag assembly (100) capable of withstanding sterilization by gamma irradiation. The bag (100) includes two walls, each wall composed of at least one sheet (176, 178) of a fluoropolymer film, and a fitment (200). The first and second walls are attached to the fitment (200) along one edge (148) of the bag assembly (100) and sealed to each other along a perimeter (142, 144, 146, 147, 149) of the bag assembly (100).

A non-shrink, irradiated packaging film includes first, second, third, and fourth layers of polyamide (PA); a first polyethylene vinyl alcohol (EVOH) layer between the first and second PA layers; a second EVOH layer between the third and fourth PA layers; a mid-layer between the second and third PA layers; and first and second polyethylene (PE) layers. The first, second, third, and fourth PA layers, the first and second EVOH layers, and the mid-layer are between the first and second PE layers. The mid-layer may be formed from a polymer.

The present invention relates to a method for manufacturing a single-faced thin polarizing plate, including: supplying a process film to one surface of a polarizer having a thickness of 50 m or less; supplying a protection film to the other surface of the polarizer; forming an adhesive layer by supplying an adhesive composition between the polarizer and the protection film; pressing a laminate of the process film/the polarizer/the protection film by disposing a pair of pressing units on a surface of each of the process film and the protection film; and stripping the process film, in which stripping force between the polarizer and the process film is 1.0 N or less.

A recyclable packaging film includes an irradiated first film and a second film laminated to the first film. The first film includes a first polypropylene layer, a second polypropylene layer, and an ethylene vinyl alcohol (EVOH) layer between the first and second polypropylene layers.
