  • Patent number: 10315790
    Abstract: A method of producing packages from a tube of packaging material for a liquid food product, comprises reforming a flat web of packaging material into a cylindrical tube, feeding the tube of packaging material in first direction, filling the tube with a liquid food product, transversally sealing the tube, at regular intervals, into separate package volumes, wherein a longitudinal axis of every second transversal seal being parallel to each other, and a longitudinal axis of each adjacent transversal seal being perpendicular to each other, and wherein a longitudinal axis of each transversal seal is angled in a range between 15-30° in relation to a plane which is orthogonal to the longitudinal axis of the tube of packaging material. Also disclosed is a packaging material for use in the method, a package produced with the method, and a filling machine performing the method.

  • Publication number: 20080182055
    Abstract: The disclosure relates to a packaging laminate (10) for a packaging container for a food product intended to be frozen, comprising a core layer (12) and outer, liquid-tight layers (14, 16), the packaging laminate (10) including an outer, thermosealable layer (14, 14a) which, at least in selected part regions thereof displays a brittle point between ?25° C. and +20° C. The invention also relates to a packaging container (30) for a food product intended to be frozen, which is formed from the packaging laminate according to the present invention.

  • Patent number: 5960975
    Abstract: A packaging material web for a self-supporting packaging container wall which includes a number of continuous wall panels manufactured from flexible material layers which are interconnected with one another by means of a pattern of seals. Between the seals, there are formed cells which are inflatable with a view to imparting to the material the requisite rigidity. A packaging container manufactured from the packaging material comprises a number of wall panels provided with inflatable cells, the length of the wall panels on inflation of the cells being reduced so that the height of the packaging container shrinks. Along one of the vertical side edges of the packaging container, there is a sealing joint (10) which is less flexible and counteracts such shrinkage so that the packaging container tends to be warped. In order to counteract this, the seals defining the cells are given asymmetric form, with one narrow and one broad end.
