Title:
HEAT-SHRINKABLE POLYESTER-BASED FILM
Document Type and Number:
WIPO Patent Application WO/2014/021120
Kind Code:
A1
Abstract:
[Problem] To provide a heat-shrinkable polyester-based film which: has ample heat-shrinking properties in a main shrinking direction, which is the longitudinal direction, even without containing much of a monomer component that could be an amorphous component; has a low heat shrinkage rate and high mechanical strength in the width direction orthogonal to the main shrinking direction; can be produced also to include a PET bottle recycled raw material; and has less thickness unevenness. [Solution] A heat-shrinkable polyester-based film that has ethylene terephthalate as a main constituent component and contains 0 to 5 mol% of a monomer component that could be an amorphous component in the total polyester resin component, the main shrinking direction being the longitudinal direction, wherein the heat shrinking properties in the longitudinal direction and width direction and the refractive index satisfy specific ranges.
