Abstract: In one embodiment, the invention relates to an ink-imprinted and reusable multilayer cling film of at least one layer for use in combination with a substrate having a rigid smooth surface comprising a non-vinyl flexible polymer cling film which has two smooth surfaces, is substantially free of added plasticizer and provides a 180° peel force after application to glass of from about 30 to about 2500 gms after aging in a 140° F. oven for 72 hours. In another embodiment, the invention relates to an ink-printed and reusable multilayer cling film of at least two layers which can cling to substrates having a rigid smooth surface without the use of an adhesive material.

Abstract: An oriented polymeric in-mold label film comprises a hot-stretched, annealed, linerless self-wound film lamina and has a face layer for printing and a base layer which includes a heat-activatable adhesive. The heat-shrinkability of the film is balanced thickness-wise to minimize curl and allow the film to be printed in conventional label-printing presses. An antistat may be included only in the charge for the base layer which includes the heat-activatable adhesive. In the manufacture of labelled blow-molded containers, sheets and labels formed from the 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.

Abstract: An oriented polymeric in-mold label film includes a hot-stretched, annealed, linerless self-wound film lamina and has a face layer for printing and a base layer which includes a heat-activatable adhesive. The film may be hot-stretched and annealed at softening and annealing temperatures exceeding the temperature at which the adhesive is activated by passing the film across rolls for imparting heat to and removing heat from the film under controlled time-temperature-direction conditions to heat at least the majority of the thickness of the film to such softening and annealing temperatures without sticking of the adhesive to the rolls. The heat-shrinkability of the film is balanced thickness-wise to minimize curl and allow the film to be printed in conventional label-printing presses. An antistat may be included only in the charge for the base layer which includes the heat-activatable adhesive.

Abstract: A uniaxially oriented coextruded polymeric in-mold label film includes a uniaxially hot-stretched, annealed, linerless self-wound film having a face layer for printing and a base layer which includes a heat-activatable adhesive. The heat-shrinkability of the film is balanced thickness-wise to minimize curl and allow the film to be printed in conventional label-printing presses.
