| 20110174439 | VAPOR DISPERSIBLE PLASTIC FILM WITH PAINT ADHERENCE & CLING - A co-extruded plastic film comprises an outer layer formed of a high density polymer or co-polymer having a high surface energy, such as a medium molecular weight high density polyethylene that is corona treated or includes a relatively polar polymer, a core layer preferably formed of a polyolefin, which can include linear low density polyethylene or a foamed polymer preferably produced by an endothermic blowing agent, and an inner layer formed of a polymer having good cling properties that includes a filler of sufficiently large particle size and in a sufficiently large amount that vapors can escape laterally from under the film. 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 while having good lateral transmissivity of vapors. | 07-21-2011 |
| 20100003463 | VAPOR DISPERSIBLE PLASTIC FILM WITH PAINT ADHERENCE & CLING - A co-extruded plastic film comprises an outer layer formed of a high density polymer or co-polymer having a high surface energy, such as a medium molecular weight high density polyethylene that is corona treated or includes a relatively polar polymer; a core layer preferably formed of a polyolefin, which can include linear low density polyethylene or a foamed polymer preferably produced by an endothermic blowing agent; and an inner layer formed of a polymer or co-polymer having good static or physical cling properties that includes a filler of sufficiently large particle size and in a sufficiently large amount that water vapor can escape laterally from under the film. The inner layer also can include a desiccant and can 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. | 01-07-2010 |
