  • Publication number: 20120308789
    Abstract: Imageable multilayer films are provided which include at least a core layer comprising a pigment or other colorant, a clear sealant layer, and an image-side tie layer intermediate the core layer and the sealant layer, where the tie layer comprises a cavitating agent. The sealant layer may include a first polymer component having a heat of fusion of less than 75 J/g and a second polymer component. The multilayer film may have a seal strength greater than about 200 g/2.54 cm for a seal formed on a crimp sealer at a temperature of at least 93.3° C. The multilayer film may be biaxially oriented, an image may be effected on the film without the use of inks, and the film may be useful in packaging applications.

  • Patent number: 6534189
    Abstract: A uniaxially heat-shrinkable, biaxially oriented, multilayer film for use as a tobacco pack or carton overwrap having a polypropylene-containing core layer comprising at least 70 wt % of said multilayer film and at least one polyolefin-containing skin layer adjacent said core layer is prepared by biaxially orienting a coextrudate and thereafter orienting said coextrudate by stretching 10 to 45% in the machine direction. The core layer contains isotactic polypropylene and a modifier which reduces the crystallinity of the polypropylene-containing core. Such modifiers can be selected from the group consisting of atactic polypropylene, syndiotactic polypropylene, ethylene-propylene copolymer, propylene-butene-1 copolymer, ethylene-propylene-butene terpolymer, polyethylene and linear low density polyethylene. The skin layer can be selected from the group consisting of polypropylene, ethylene-propylene copolymer, polyethylene, and ethylene-propylene-butene-1 terpolymer and contains silicone oil.
