摘要
A co-extruded plastic film comprises an outer layer (12) formed of a polymer or co-polymer having a high surface energy, such as corona treated high density polyethylene; a core layer (14) preferably formed of a polyolefin, which can included a foamed polymer preferably formed by an exothermic blowing agent; and an inner layer (16) that includes a filler of sufficiently large particle size and in an sufficiently large amount that water vapor can escape laterally from under the film. The inner layer can also include a desiccant and be embossed. This film allows vapors to disperse and can also be moisture absorbent and vapor permeable. The film also has the benefit that one surface has high paint adherence and the opposite surface clings to a substrate, typically a painted metal or simple metal surface.
