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.

Method of forming a reusable coextruded embossed nonadhesive protective cover

A reusable, non-adhesive protective cover is disclosed which includes a first layer having an exterior surface designed to contact a structure or object during use and a second layer having an exterior surface designed to be spaced away from the structure or object. Each of the first and second layers are formed from a thermoplastic film and are joined together to form a laminate which is free of polyvinyl chloride. Each of the first and second layers contains at least about 5% of a flame retardant. The first layer has a static coefficient of friction of at least about 0.5. The second layer exhibits attachment and release capabilities such that a joint tape can be used to join adjacent sheets of the reusable, non-adhesive protective cover together and the joint tape can be removed without damaging the reusable, non-adhesive protective cover.
