Abstract

PURPOSE:To provide a method of producing a buffer corner pads for packages which are made of foamed plastics, especially foamed polyolefin. The pads are rendered thin-walled and less suffers fusion failure, since they are formed by cutting an article obtained through foaming of polyolefin particles.
