| titleOfInvention | Heat shrinkable polyester film |
| abstract | PROBLEM TO BE SOLVED: To use a raw material derived from a biomass resource which does not substantially contain an amorphous component and / or a recycled PET, preferably a heat-shrinkable polyester film having a high ratio of recycled PET, and heat-shrinkable in the width direction. An object of the present invention is to provide a heat-shrinkable polyester-based film having a high rate and a small thickness unevenness, and a method for producing the same. A heat-shrinkable polyester-based film containing 90 mol% or more of an ethylene terephthalate unit in 100 mol% of all ester units, and at least a part of ethylene glycol and / or terephthalic acid constituting the ethylene terephthalate is biomass. Contains polyester resin derived from resources or recycled from PET bottles, A heat-shrinkable polyester-based film characterized by satisfying the following requirements (A) to (D). (A) Thermal shrinkage in the width direction when contracted in hot water at 90 ° C for 10 seconds is 50% or more and 75% or less (B) Thermal shrinkage in the longitudinal direction when contracted in hot water at 90 ° C for 10 seconds Rate is -6% or more and 14% or less (C) Thickness unevenness in width direction is 1% or more and 20% or less (D) Maximum heat shrinkage stress in width direction is 4 MPa or more when contracted in hot air at 90 ° C for 30 seconds. 13 MPa or less [Selection diagram] None |
