Patent ID: 7939169

Claim:
A multilayer film having at least 3 layers: (A) an adhesive layer in an amount of from 5 to 25 volume percent consisting essentially of at least about 40 weight percent of an ethylene/alkyl acrylate copolymer having a Vicat point (ASTM D1525) of no more than 40° centigrade (° C.), at least about 1 and at most about 10 weight percent of an ethylene/α, β-ethylenically unsaturated carboxylic acid copolymer, and at least about 20 weight percent of a low density polyethylene, LDPE having a density of from about 0.91 to about 0.94 g/cm 3 , and 0 to at most about 7 weight percent filler, hereinafter referred to as composition A; (B) a core layer, in an amount of 50 to 90 volume percent comprising at least about 20 weight percent linear low density polyethylene (LLDPE), at least about 20 weight percent low density polyethylene different from LLDPE, at least about 10 weight percent high density polyethylene and 0 to at most about 5 weight percent filler, hereinafter referred to as composition B and (C) a melt barrier layer in an amount of from 5-25 volume percent, that is a layer that effectively prevents molten adhesive film layer polymer from migrating through the multilayer film surface to an external surface of the multilayer film consisting essentially of at least about 90 weight percent high density polyethylene, hereinafter referred to as composition C, with the remainder of the polymer being another polyolefin, and in each layer, the percentages being based upon combined weight of polymers and filler and selected to total 100 percent by weight, wherein the multilayer film is strippable, that is removable, from a surface leaving little residue visible to the eye or sufficient to stick to other substances or interfere with further use.
