Abstract: A method of improving hot tack and/or seal strength in a multi-layer film by selecting a first PE comprising at least one of mPE, LDPE or LLDPE to form a first layer and selecting a blend comprising a mPE and a PP to form an outer layer; and coextruding the first PE and the blend to form the multi-layer film comprising the first layer and the outer layer; wherein the inner layer comprises at least one component having a final melting point at least about 15° C. higher than a final melting point of at least one component of the first layer, wherein the multi-layer film has a maximum hot tack at least about 25% greater than a similar multi-layer film with 0-weight % of the PP in the inner layer.

Abstract: A film comprising a blend of: i) a homopolymer of ethylene having a Mw/Mn of 3 or a copolymer of ethylene and up to 50% weight % of a C3 to C20 olefm, the copolymer having a CBDI of 50% or more; ii) a homopolymer of propylene or a copolymer of propylene and up to 50 weight % of a comonomer selected from the group consisting of ethylene and C4 to C20 alpha-olefms; and iii) a polymer produced in a high pressure process using a free radical initiator.
