Abstract: A sealable polymeric film structure comprising (a) a core layer including a thermoplastic polymer, the core layer having a machine side and a product side that is on a side of the film opposite from the machine side; and (b) a sealable skin layer positioned on the product side of the core layer, the sealable skin layer including a thermoplastic polymer, wherein an exterior surface of the sealable skin layer has a receding Cahn value of at least about 0.48; and wherein in some heat—sealable embodiments, the sealable skin layer sealed to itself has a MST of from about 175° F. to about 220° F., with a jaw pressure of 20 psi for 0.75 seconds and a minimum acceptable seal strength of 200 g/in at 175° F., on a Wrap-Ade™ Crimp Sealer Model J or K.

Abstract: This disclosure relates to a package and a method of making the package. The package comprises (a) a web material to form an enclosed package comprising a seal having two seal ends and a package side edge, and wherein the seal is a fin seal or an overlap seal; (b) a first tear initiation point located on the package side edge; and (c) a second tear initiation point, wherein the second tear initiation point is located on the seal.

Abstract: A multilayer white opaque plastic film, heat-sealable on one or two sides, suitable for packaging uses. The multilayer film includes a cavitated core layer of polypropylene, a top intermediate tie-layer of polypropylene with interspersed titanium dioxide, a bottom intermediate tie-layer of polypropylene, a top and a bottom skin layer. The top skin layer is formed from a polylefin terpolymer or polypropylene. The top skin layer may include silicon dioxide and an antiblock agent, and optionally may be corona treated. The bottom skin layer is formed from a polylefin terpolymer, and may also include silicon dioxide and one or more antiblock or slip agents.
