Title:
PLASTIC BOTTLE
Document Type and Number:
Japanese Patent JP2023145475
Kind Code:
A
Abstract:
To provide a polyester-based heat-shrinkable film capable of effectively suppressing the blocking phenomenon when being recycled.SOLUTION: A plastic bottle includes a polyester-based heat-shrinkable film 10 derived from a first polyester resin and a second polyester resin as a plurality of polyester resins having different crystallinity. The first polyester resin includes terephthalic acid, and the reaction amount of ethylene glycol is in a range from 50 to less than 90 mol%. The second polyester resin includes terephthalic acid and the reaction amount of ethylene glycol is 90 mol% or more. When the predetermined isothermal crystallization measurement is performed, an exothermic peak appears within 12 minutes from the start, including a cooling process time, and the calorific value of the exothermic peak is between 5 and 35 J/g. The thermal shrinkage in the main shrinkage direction measured under prescribed conditions is 20% to 60%.SELECTED DRAWING: Figure 1
