STRETCH/SHRINK LAYERED FILM AND PROCESS FOR PRODUCING THE SAME

摘要

A stretch/shrink layered film composed of at least three layers, characterized in that the two surface layers comprise as the main component an ingredient (A) which is an ethylene polymer, the one or more interlayers comprise as the main component an ingredient (B) which is an ionomer resin composition, the proportion of the thickness of the interlayers in the overall thickness of the film is 35-90%, and the sum of the degree of machine-direction thermal shrinkage and that of transverse-direction thermal shrinkage of the film in 10-second immersion in an 80°C oil bath is 30% or higher.
