Abstract:
An in-mold labelled plastic bottle or other substrate comprising a substrate body, a label formed of a coextruded layered film material and containing within itself a separation interface, said label being applied to the substrate body, said layered film material comprising two polymeric film plies each comprising one or more film layers, said film plies being on contact with each other and presenting to each other surfaces of different composition at a pair of contacting interior faces joined at said separation interface, one of said film plies comprising printable in-mold label facestock, including a printable face layer, the other of said film plies comprising a core or stiffening layer of polymetric film and a heat-activatable adhesive layer, said film plies adhering to each other at said separation interface to a sufficiently high degree to withstand the maximum process separation force imposed at said separation interface as said layered film material is printed and as labels cut therefrom are deployed from affixation on said substrate, said film plies adhering to each other at said separation interface to a sufficiently low degree to allow them to cleanly and readily separate from each other at said separation interface under the imposition of a separation force greater than said maximum process separation force.
