    摘要： A method for producing a heat sealable structure includes coextruding a substrate layer including a white opaque, cavitated polyolefin film with a second layer which includes a heat sealable ethylene propylene random copolymer, ethylene-propylene block copolymer or ethylene-propylene butene-1 terpolymer; biaxially orienting the coextrudate; treating to increase surface energy; applying a primer coating on the surface; and, applying a surface layer which includes vinylidene chloride copolymer.

    摘要： A pressure-sensitive coating for reducing seal is applied to an exposed surface of a pressure-activated adhesive. The coating is preferably deposited on the exposed surface of the adhesive by decomposition of a decomposable precursor in the presence of plasma. The employed decomposable precursor may include a hydrocarbon gas whereby an amorphous layer of interconnected carbon atoms is deposited on the surface of the adhesive, or a silicone-containing compound whereby the deposited coating is an amorphous layer of interconnected silicone and oxygen atoms.

    摘要： A pigmented, heat-sealable coating composition for application to a primer-coated, oriented mono-layer or multilayer polyolefin film is provided which comprises a blend of (a) a binding and oxygen barrier effective amount of a heat-sealable polyvinylidene chloride homopolymer and/or polyvinylidene chloride copolymer containing at least about 50 weight percent copolymerized vinylidene chloride, (b) an amount of wax sufficient to result in a significant reduction in the coefficient of friction of a film to which the coating composition is applied and (c) an amount of pigment sufficient to result in a significant reduction in the light transmission property of a film to which the coating composition is applied.Oriented polyolefin films coated with the foregoing compositions possess excellent seal strength and hot tack properties, good blocking resistance, low coefficient of friction, low oxygen transmission rate and low light transmission.
