Abstract: A laminated polypropylene-based film suitable for use as a lidding film having an exterior film, a barrier layer, and a sealing layer. The lidding film has a total composition including high levels of polyolefin-based polymers and polypropylene-based polymers such that the material can be processed efficiently in a polypropylene recycling process. Advantageously, the film retains the properties required to suitably withstand sterilization and pasteurization processes and produce a high-quality packaged product.

Abstract: A laminated polypropylene-based film suitable for retort packaging having an exterior film, a barrier layer, and a sealing layer. The retort packaging film has a total composition including high levels of polyolefin-based polymers and polypropylene-based polymers such that the material can be processed efficiently in a polypropylene recycling process. Advantageously, the film retains the properties required to suitably withstand the retort process and produce a high-quality shelf-stable packaged product.

Abstract: The present invention relates to a method for the production of a self-venting packaging for use in heating a food item in a microwave oven, said packaging comprising a rupturable valve seal (3), said rupturable valve seal comprising an inside-inside seal, creating a weak point on said packaging, suitable to break in case of overpressure inside the packaging, said method comprising the following subsequent steps: providing an open plastic packaging; filling said packaging with a food item; —sealing the plastic packaging to obtain a closed pack via a closing seal with the food item therein ready to be sterilised; heat treating said food item; providing a rupturable valve seal (3) on the pack by ultrasound seal technology.

Abstract: 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, characterized 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.

Abstract: The present invention is related to easy-to-open packaging (1) comprising an easy tearable multilayer laminate (2), said laminate comprising at least two polymer layer wherein at least one of said polymer layer comprises a scratched surface (6, 6?) forming a scratched polymer layer (11), said scratched surface comprising a multitude of scratched lines parallel to the extrusion direction (2) of said scratched polymer layer, the scratched lines creating a predetermined tear direction of the packaging.

Abstract: The invention concerns composites with excellent barrier properties to gases and water vapor. Such composites can be used, e.g., in foodstuff packaging or as technical membranes. The outstanding barrier effect is achieved by arranging on a substrate material, which, for example, may consist of biodegradable polymers, at least two films. At least one of these films consists of an organic-inorganic hybrid polymer (ORMOCER), at least one further film of a further barrier material or of a substrate material.

Abstract: A process for fabrication of a composite film including two films, includes: depositing by evaporation in a vacuum at least one intermediate functional layer which is non-metallic and transparent, and which functions as at least one of a barrier layer or a bonding layer, onto at least one of the two films; and joining the two films under conditions effective to create a bond therebetween; wherein, when at least one intermediate functional layer is deposited onto each of the two films, these two films are joined together along the surfaces thereof which carry the deposited at least one intermediate functional layer, and when at least one intermediate functional layer is deposited onto only one film of the two films, the one film is joined to the other of the two films along the surface of the one film which carries the deposited at least one intermediate functional layer.
