Described herein are packaging materials and their use in manufacturing packaging containers having an opening device, and intended for food products. In some embodiments, a packaging material for a packaging container for liquid or semi-liquid food includes: a bulk layer made of paper or paperboard; a heat-sealing layer; a barrier layer arranged between the bulk layer and the heat-sealing layer; and a laminate layer arranged between the barrier layer and the bulk layer. The packaging material can include one or more weakenings in direct or indirect contact with an attenuation in the packaging material, the one or more weakenings defining a consumer opening area. The attenuation can provide a material bridge for an injection molded opening device. In one embodiment, the attenuation can include the heat-sealing layer, the barrier layer, and the laminate layer, but not the bulk layer.

Packaging material and packaging container having an opening device made therefrom

Package material comprises one or more layers of plastic laminate, a first side, a second side and an penetration area (). Two weakening lines () extend from the penetration area () creating a space in between and thus forming an opening ( ) in the package material. The package material comprises a plastic opening device ( ), with a first and second portion ( ) attached to the first and second side, respectively and a material bridge ( ) penetrating through the penetration area (). The second portion covers at least partly the penetration area and comprises a guiding portion ( ) extending from the penetration area () onto the space adjacent and to the weakening lines () as to facilitate rupturing substantially along the at least one weakening line.

Package material and package container formed with said material

A package material may include one or more layers of plastic laminate, a first side, a second side and a penetration area. A weakening line may extend from the penetration area and may provide an opening area in the package material. The package material may include a plastic opening device, with a first and second portion attached to the first and second side, respectively, and a material bridge penetrating through the penetration area. The second portion may cover at least partly the penetration area and may include a guiding portion extending from the penetration area adjacent to the at least one weakening line as to facilitate rupturing substantially along the at least one weakening line.

A package material comprises a multilayer material structure with layers of plastic laminate, a penetration area () and two weakening lines () creating an area in between. The package material comprises an opening device with a first () and second () portion attached to respective sides and a material bridge () penetrating the penetration area and connecting the first portion to the second portion. The second portion at least partly covers the penetration area and comprising a rupture section () covering at least partly the two weakening lines. The rupture section comprises one or more rupture recesses (-) disposed over or adjacent to the weakening lines for guiding a rupture of the multilayer material structure along the weakening lines.
