Zusammenfassung:	A polyethylene cold seal film includes a main body layer constituted by a polyethylene film, a cold seal adhesive externally exposed on one side of the main body layer, and a cold seal release layer externally exposed on an opposing side of the main body layer, with the cold seal release layer also being constituted by a polyethylene film. The film can be advantageously provided in roll form, particularly usable in wrapping food products, with the wrapping being completely and readily recyclable, while being at least essentially void of any polypropylene polymers. The overall film can also have other layers, including a tie layer positioned between the main body layer and the cold seal release layer, a barrier layer positioned between the main body layer and the tie layer; and an ink layer positioned between the tie layer and the cold seal release layer.
