Abstract (en)
[origin: EP0957045A1] The packaging film (12) comprises two films connected by a permanent adhesive (38) away from the opening and reclosure system (18). The inner film (28) has a first perforation (32) forming an opening (22) and an outer film (30) has a second perforation (34) forming a closure flap (20) covering the first perforation. A semi-permanent adhesive (24) between both films under the closure flap hold the latter closed. Independent claims are made for: a) a packaging container using the packaging film; b) a process for the continuous manufacture of a packaging film with an integrated system for opening and reclosure of a package using the film (12) in which the outer film (30) is coated with both the permanent (38) and semi-permanent (24) adhesives, the second and first perforations are cut in both films and these are joined together; b) process equipment for manufacturing the packaging film with first and second coating stations for applying the permanent and semi-permanent adhesives onto the outer film, two cutting stations for producing both sets of perforations in the appropriate films, a coating station for joining both films together to form the film and a process control unit. The second perforations preferably do not penetrate through the entire thickness of the outer film. The closure flap (20) is free of adhesive and forms a gripping and tear-off aid.
