CA 2323374

A patch bag has a heat-shrinkable patch film adhered to a heat-shrinkable bag film. The patch film contains at least one member selected from the group consisting of propylene homopolymer and propylene copolymer. The film used as the patch is preferably irradiated during its production. This polymer, in a patch film of a patch bag, can be selected to provide especially high elasticity and low crystallinity, thereby providing good impact strength, ease of processing (i.e., good orientation), high free shrink at 85°C.
