POLYMERIC FILMS

摘要

Oriented polyolefin films having an opaque polypropylene layer with at least onefurther polymeric layer adhered to one surface thereof the outer surface of the film defined by the said at least one further polymeric layer having a matt appearance and being formed from a blend of incompatible polymers and the other surface of the film having a higher gloss than layer with the matt appearance, the film being substantially free of antistatic additives and not treated to increase its surface energy. Films in accordance with the present invention can be used as wall charts which can be written on and will adhere to surfaces as a result of static cling.
