Method of forming a reusable coextruded embossed nonadhesive protective cover

A method of forming a reusable, co-extruded embossed non-adhesive protective cover, comprising the steps of:

• a) extruding a first layer of a thermoplastic film onto a rotatable cast roll, said first layer having an interior surface and an exterior surface, said first layer containing from between about 5% to about 20% of a flame retardant;
• b) extruding a second layer of a thermoplastic film onto said interior surface of said first layer to form a co-extruded laminate, said second layer containing from between about 77% to about 79% of linear low density polyethylene film, about 10% of linear low density polyethylene, about 10% of a flame retardant, and from between about 1% to about 3% of a colorant, said second layer having an exterior surface exhibiting attachment and release capabilities such that a joint tape can be used to join adjacent sheets of the reusable, non-adhesive protective cover together,
• c) advancing said co-extruded laminate between a nip formed by an embossing roll and a rubber roll, said exterior surface of said first layer contacting said embossing roll to form a co-extruded embossed laminate;
• and
• d) passing said co-extruded embossed laminate around at least a portion of a chill roll to cool said laminate and form said reusable, co-extruded embossed non-adhesive protective cover, said cover being free of polyvinyl chloride.

A method of forming a reusable, co-extruded embossed non-adhesive protective cover, comprising the steps of:

• a) extruding a first layer of a thermoplastic film onto a rotatable cast roll, said first layer containing from between about 18% to about 20% of low density polyethylene film, about 70% hydrogenated styrene block copolymer, and from between about 10% to about 12% of a flame retardant, said first layer having an interior surface and an exterior surface, and said first layer having a static coefficient of friction of at least about 0.5;
• b) extruding a second layer of a thermoplastic film onto said interior surface of said first layer to form a co-extruded laminate, said second layer having an exterior surface exhibiting 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 said second layer contains from between about 5% to about 20% of a flame retardant;
• c) advancing said co-extruded laminate between a nip formed by an embossing roll and a rubber roll, said exterior surface of said first layer contacting said embossing roll to form a co-extruded embossed laminate;
• and
• d) passing said co-extruded embossed laminate around at least a portion of a chill roll to cool said laminate and form said reusable, co-extruded embossed non-adhesive protective cover, said cover being free of polyvinyl chloride.
