Abstract

A method of forming a reusable, non-adhesive protective cover is disclosed which includes extruding first and second layers of a thermoplastic film onto a rotatable cast roll. The first layer has an interior surface and an exterior surface. The second layer is extruded onto the interior surface of the first layer to form a co-extruded laminate. The second layer has an exterior surface exhibiting attachment and release capabilities such that a joint tape can be used to join adjacent sheets of the protective cover together. The co-extruded laminate is then advanced between a nip formed by an embossing roll and a rubber roll whereby the exterior surface of the first layer contacts the embossing roll to form a co-extruded embossed laminate. Lastly, the co-extruded embossed laminate is passed around at least a portion of a chill roll to cool the laminate and form the reusable, co-extruded embossed non-adhesive protective cover.
