| 摘要 |
The present invention is directed to a multilayer polymer film for application to and removal from a substrate, having controlled surface adhesion and peelably removable from a surface, the film having a layer comprising components (A) at least one polyolefin, (B) an adhesive composition in an amount equal to or greater than 3 weight percent, (C) a tackifier composition in an amount of from 1 to 12 weight percent, (D) at least one colorant in an amount from 0 to 15 weight percent, (E) anti-block additive in an amount of less than 1 weight percent, and (F) roughening material in an amount of less than or equal to 20 weight percent, each based on total weight of the adhesive layer; the components (A) through (F) with optional incidental carriers and additives being 100 percent by weight of the adhesive layer; wherein the adhesive composition consists essentially of ethylene/methyl acrylate and ethylene/acrylic acid in a weight ratio of from 60:40 to 50:15, that is, 77:23, ethylene/methyl acrylate to ethylene/acrylic acid; the tackifier is selected from a terpene phenolic resin or an acrylic hot melt resin; and the roughening material has an average particle size ranging from 20 to 60 microns.
