Abstract: A film for use as a rubber bale wrap includes a thermoplastic containing a release agent and having a microembossed surface to provide the film with a gloss of 10 or less.

Abstract: A double layer thermoplastic film is used in Pass-Through stretch wrapping of goods. The double layer improves the tear resistance and puncture resistance of the film.

Abstract: The present invention is directed to an apparatus and method useful for inducing blocking in plastic film samples under known laboratory conditions. The test device of the present invention comprises a base platen and a movable platen disposed for cooperation to engage and apply a known, preferably multiplied, compressive force to a plurality of plastic samples. The compressive force is transferred to the movable platen through a thrust member from a lever arm pivotable about a pivot, preferably a hinge, above the base platen. Along the lever arm are disposed a plurality of weight receiving locations for engagement by a hanger supporting one or more selected weights. The test device of the present invention permits higher compressive forces to be applied to plastic test samples under laboratory conditions without requiring the use of heavier weights and produces more reproducible compressive forces than prior art methods.
