Patent ID: 8710130

Claim:
A layered adhesive construct comprising a backing layer and at least one layer of a pressure sensitive, hot melt processable adhesive composition comprising polypropyleneoxide in the content of above 10% (w/w) of the final adhesive, and at least one polar polyethylene copolymer, wherein the content of the polyethylene copolymer is 10-50% (w/w) of the final adhesive, the polyethylene copolymer has a melt flow index below 2 g/10min (190° C/21.1 N), wherein the at least one polar polyethylene copolymer is selected from the group consisting of ethylene vinyl acetate, ethylene vinyl acetate carbon monoxide, ethylene butyl acetate, ethylene vinyl alcohol, ethylene butyl acrylate, ethylene butyl acrylate monoxide, and combinations thereof, provided that when the polar polyethylene copolymer is ethylene vinyl acetate, the ethylene vinyl acetate has a content of at least 40% (w/w) vinyl acetate.
