Abstract
A coextruded film having a matte surface layer is prepared by forming the layer from a blend of polyisobutylene and high density polyethylene. The film preferably has a heatseal layer on the other surface. In addition to having low gloss for consumer appeal, the matte surface layer has a medium coefficient of friction for good machinability and excellent heat resistance to facilitate heatsealing. The film is especially useful as an overwrap for packaging consumer products.
