Tinted heat-shrinkable multilayer films comprising a vinylidene chloride-vinyl chloride copolymer

摘要

A transparent heat shrinkable, multilayer film comprising: (a) at least one layer comprising a vinylidene chloride-vinyl chloride copolymer; and (b) at least one layer comprising a thermoplastic polymer; and (c) a sufficient amount of a dioxazine violet pigment to provide a film which retains an aesthetically acceptable violet appearance despite exposure to elevated temperatures and/or irradiation.
