<p>#CMT# #/CMT# The multilayer film has a sealing layer (3) made from a heat sealable polymer at a packaging inner side and a cover layer (4) that is provided for forming the packaging outer side. The film is provided with a laser notch (7) which partially separates the cover layer. A perforation line forming bars and slots (9) is arranged along the laser notch. The slots of the perforation line partially pass through the sealing layer. The cover layer is made from polyester, oriented polyamide, oriented polypropylene or bioriented polyproplylene. The sealing layer is made of polyethylene. #CMT# : #/CMT# An independent claim is included for a method for manufacturing a film. #CMT#USE : #/CMT# Multilayer film for fracture packaging. #CMT#ADVANTAGE : #/CMT# The multilayer film has a sealing layer made from a heat sealable polymer at a packaging inner side and a cover layer that is provided for forming the packaging outer side, where the film is provided with a laser notch which partially separates the cover layer, and thus ensures that the simple fracture packaging is possible by the multilayer film with little effort. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a film. 1 : Weakening line 3 : Sealing layer 4 : Cover layer 7 : Laser notch 9 : Slots.</p> |
