Publication number: 20150344210Abstract: The present invention discloses a self-venting package (6) for packing a food preparation and warming it up comprising at least one flexible film forming a first wall comprising a sealant layer (9) and a support layer (10), said flexible film being sealed by a peripheral seal (4) onto a second wall or on itself, thereby forming a main enclosure confining the food preparation; a rupturable seal (3) isolating a venting hole (1) from said main enclosure, said rupturable seal being arranged for opening, in use, a path to the venting hole upon internal pressure increase in said main enclosure, characterised in that a specific region (5) of the rupturable seal is weakened by means of a welded area with a reduced sealant layer thickness, said welded area guiding, in use, the rupture of said rupturable seal to the venting hole.Type: ApplicationFiled: February 17, 2012Publication date: December 3, 2015Applicant: Amcor Flexibles Transpac NVInventor: Helmar Utz

Patent number: 8056716Abstract: The present invention relates to a tamper-evident push-through packaging secured against fraudulent reuse comprising: —a polymer base web (1) comprising at least one pocket; —a multilayer lidding film (2) covering said pocket, said multilayer lidding film (2) comprising on its seal side a coextruded polymer film, said coextruded polymer film comprising a push-through polymer layer (3) sealed on the base web by a permanent seal and a peelable protective polymer layer (4), the polymers of both layers (3,4) being incompatible and in direct contact with each other, without interlayer, the adhesion between said push-through polymer layer (3) and said peelable protective polymer layer (4) being lower than the seal strength between said polymer base web (1) and said push-through polymer layer (3), wherein, in use, the push-trough layer leaves a seal seam (6), after removing the part of the push-trough layer (3) covering the pocket and wherein said protective layer (4) cannot be resealed by a heat sealing process onType: GrantFiled: January 28, 2009Date of Patent: November 15, 2011Assignee: Amcor Flexibles Transpac NVInventors: Gerard Fonteyne, Tony Malfait, Erik Bögels, Kris Buysens
