SEALANT FILM FOR LID MATERIAL OF CUP-SHAPED CONTAINER FOR ICE CANDY, AND LID MATERIAL

摘要

PROBLEM TO BE SOLVED: To enhance heat sealability without impairing openability of a lid material of a cup-shaped container for an ice candy like a newly developed container formed of A-PET.SOLUTION: A sealant film 6 for a lid material of a cup-shaped container for an ice candy is formed by bonding a seal layer 13 to a base material layer 11. The sealant layer 13 is formed by blending any resin of polyester and polyolefin with low Tg polyester having a lower glass transition temperature than that of the resin and has a glass transition temperature of -30°C or lower so that the low Tg polyester becomes 50 mass% or more.SELECTED DRAWING: Figure 1
