Abstract
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.
