IN-MOLD LABEL FILM AND METHOD

摘要

An oriented polymeric in-mold label film (10) comprises a hot-stretched, anneale d, linerless self-wound film lamina and has face layer (12) for printing and a base layer (14) which includes a heat-act ivatable adhesive. The heat-shrinkability of the film (10) is balanced thickness-wise to minimize curl and allow the film (10) to be p rinted in conventional label-printing presses. An antistat may be included only in the charge for the base layer (14) which includ es the heat-activatable adhesive. In the manufacture of labelled blow-molded containers, sheets and labels formed from th e film may be handled at high speeds while maintaining accurate registration and dimensional and positional integrity even in the absence of any reinforcing backing, yet the labels perform well on deformable containers such as shampoo bottles.
