发明名称 Three-layer cross-laminated film with foam core made by counter-rotating dies
摘要 A high-strength cross-laminated film with a foam core, particularly a cross-laminated film made by counter-rotating dies, and a method of producing the laminated film. The high-strength cross-laminated tubular film web is produced by counter-rotating dies; which will allow for the orientation of each extruded film layer in a different direction so as to form a cross-laminate, and whereby, concurrently with the extrusion of the molten layers, there is interposed a formed adhesive material polymer between the layers so as to provide a weak bonding or adherence therebetween while imparting a thick feel to the laminated film.
