Title:
SHRINK FILM
Document Type and Number:
Japanese Patent JP2023095930
Kind Code:
A
Abstract:
To provide a shrink film which shows excellent heat shrinkability, is free from cracking problem during shrinkage, moreover has an enough surface hardness for preventing scratches, and has a high gas barrier performance, besides allows the shrink film with gas barrier performance to be obtained with one layer, obviating the need of laminate film, therefore causing no problem of delamination during shrinkage.SOLUTION: A shrink film comprises a polyester having a structural unit derived from a diol, and a structural unit derived from a dicarboxylic acid. The structural unit derived from the dicarboxylic acid contains a structural unit derived from a 2,5-furandicarboxylic acid as a main structural unit. Preferably in the polyester, the structural unit derived from the diol contains a structural unit derived from a 1,2-ethanediol as a main structural unit.SELECTED DRAWING: None
