Patent number: 4619859Abstract: The present invention provides primarily an entirely new type multilayer oriented film suited for stretch wrapping, particularly for wrapping of foods. Its features include various excellent characteristics such as mechanical strength, transparency, heat resistance, sealability, stretchability, low temperature resistance, etc. In particular, the present invention concerns a process for producing such a multilayer film by cold stretching a multilayer containing at least one layer with a specific composition capable of a high degree of cold stretching, which enables simultaneously cold stretching of other layers made of resins which can be or cannot be stretched solely, through its cold stretching force, thereby imparting high strength to all the layers, and further applying a specific heat treatment on the stretched film to modify orientation of the film so as to increase stretchability and to stabilize dimension of the film.Type: GrantFiled: September 25, 1984Date of Patent: October 28, 1986Assignee: Asahi Kasei Kogyo Kabushiki KaishaInventors: Isao Yoshimura, Hideo Hata
