  • Patent number: 7255902
    Abstract: A paper-like multilayer barrier film comprises a filled polypropylene layer and several unfilled layers. The filled layer contains 40-75% by wt. of inorganic fillers, forms one of the two outside layers of the film, and has a thickness of at least 40 ?m. The unfilled layers include a barrier layer, a sealing layer, and optionally at least one adhesive layer. The ratio of the total thickness of the unfilled layers to the thickness of the filled layer is in the range of 1:8 to 1:1.2.

  • Patent number: 6794025
    Abstract: The inventive method for producing packaging materials consisting of a polyolefin foam layer (B) coated with a coating film (A) on at least one side, which packaging material is formable into self supporting packaging items, such as trays, by thermoforming or folding, comprises a coextrusion step or an extrusion lamination step in which step the bonding between the polyolefin foam layer (B) and the coating is achieved. With the extrusion lamination step, the method is as follows: In a first method step, a single-layer or multi-layer coating film (A) is produced by extrusion or coextrusion, in a second method step a polyolefin foam sheet (B) is produced by expansion and extrusion and in the third method step the polyolefin foam sheet (B) is coated with the coating film (A) by extrusion lamination, wherein a polyolefin bonding layer (30) is extruded between the foam sheet (B) and the coating film (A) and pressure is applied to the combination.

  • Patent number: 6691886
    Abstract: The invention relates to a resealable plastic packaging container (1) consisting of a tray (2) and a lid film (3) which in the sealing area (4) is sealed to the tray (2) such that it can be at least partly peeled back. The plastic packaging container comprises at least one hook and loop closure (9, 10, 11) whose two complementary parts (9′, 10′, 11′) are arranged opposite each other on the tray (2) and lid film (3), respectively, and by means of which the plastic packaging container can be resealed after the peel-back seal has been opened.

  • Patent number: 6203751
    Abstract: The inventive method serves for producing open containers from a flat sheeting (4) consisting of a foam material or containing at least one layer of such a material, by drawing the sheeting with the help of a female (2) and a male tool (1) and by expanding the foam material with the help of a pressure reduction. The action sequence of one cycle of the inventive method is e.g.

  • Patent number: 5891387
    Abstract: The inventive packaging item is e.g. a tray for packing fresh meat. It has at least on its bottom part (10) grooves (11) which open towards the inside of the packaging item. The openings of these grooves are narrower than the inside part of the grooves. If the groove opening is sufficiently narrow e.g 1mm or less, unwanted liquid oozing out of the packed meat is trapped in these grooves (11) and such separated from the meat and kept out of sight of a potential buyer.
