摘要：
A plastic film is disclosed having a fine grid of embossed intersecting hand-tear lines formed in the surface of the film whereby the film may be torn by hand in more than one direction. The film is composed of a polymeric material incorporating a dispersed phase. The film is particularly suited for the manufacture of articles requiring sizing of the material in both lengthwise and widthwise direction to conform the film to a desired size.
