Provided is a packaging bag in which the difficulty of tearing caused by temperature rising is resolved. The easy to open packaging bag for sealing a laminated film by heat sealing, wherein the laminated film includes an inner layer film, an intermediate layer film having an opening induction flaw formed thereon, and an outer layer film including a biaxially oriented film, and wherein a molecular orientation angle of the outer layer film is less than 49°. Also provided are a laminated film and a pouch having easy to open properties while maintaining excellent barrier properties. The laminated film is obtained by laminating (a) an outer layer film, (b) a barrier layer having an opening induction flaw, and (c) an inner layer film, and has a barrier ink covering the opening induction flaw in the barrier layer.

A food-grade container 1 is described comprising a cardboard container 10 having an opening 11, a bottom 12, side walls 13 that surround the bottom 12 and terminate at the top with a flange 14 that delimits the opening 11 of the container. The container 1 also comprises a thermoplastic film 20 coupled to the container 10 at the bottom 12, the side walls 13 and of the flange 14 by means of heat transfer. The thermoplastic film 20 comprises at least one layer of polyethylene terephthalate (PET) and having a thickness≥150 μm. The basis weight of the cardboard of the container 10 and the thickness of the thermoplastic film 20 are in a ratio from 2:1 to 1:3 (gr/m.sup.2: μm).

The present invention relates to a container of fiber pulp for packaging of food, such as vacuum packaging or modified atmosphere packaging. The container comprises a bottom part and side walls surrounding said bottom part and has at an upper end thereof a circumferential longitudinal rim part having a planer main surface being substantially parallel to the bottom plane and defining an opening of the container. The side walls further comprise a reinforcing element below the longitudinal rim part for generating an increased moment of inertia of the rim part along the longitudinal direction thereof.
