Process for packaging hot melt adhesives and plastics.

A method of packaging a plastic mass, comprising the steps of: providing a plastic mass, and surrounding the plastic mass with a characterized polymer film because said polymeric film has a composition comprising: - at least about 25% by weight is a wax material; - from about 5% to about 65% by weight of a partially crystalline ethylene-based polymer comprising a homopolymer, a copolymer, a terpolymer or an interpolymer having a melt flow index of 0.05 g / 10 min. A 800 g / 10 min. A 190 ° C and a melting point DSC from 40 to 130 ° C; - from about 0% to about 40% by weight of a thermoplastic block copolymer elastomer having an AB, ABA, A- (BA) nB, or (AB) nY structure wherein A comprises a polyvinyl aromatic block having Tg greater than 80, B comprises means rubbery block having a Tg lower than -10, Y comprises a multivalent compound, and n is an integer of at least 3; - from about 0% to about 25% by weight of an elastomer comprising a copolymer or terpolymer having a Tg lower than -10, said elastomer is selected from the group consisting of an ethylene-based elastomer, an elastomer based propylene, and combinations of ethylene based elastomers and propylene-based; - where the amount of polymer based on partially crystalline ethylene block copolymer thermoplastic elastomer and elastomer comprises about 30% or more of the total film composition; and - wherein the film composition has an enthalpy of fusion of at least about 100 J / g and an elongation value at break of at least about 100%.
