Document Type and Number:
WIPO Patent Application WO/2024/095940
Kind Code:
A1
Abstract:
Provided are: a laminated film that exhibits less deposition of cyclic oligomers, that has excellent transparency after being heated, and that has excellent recycling characteristics and is sustainable; a resin composition; and a resin composition production method. A laminated film according to the present invention includes a base material layer A formed of a first composition containing a polyethylene terephthalate resin, and a decomposition layer B formed of a second composition containing an aliphatic polyester resin. In the laminated film, the base material layer A is in contact with the decomposition layer B, and at least one of the outermost layers is the base material layer A. Preferably, the base material layer A is provided in contact with both surfaces of the decomposition layer B, and both of the outermost layers are the base material layer A.
