摘要 |
Packaging container of a material containing a skeletal layer of plastic and filler mixed into the plastic in a quantity of between 50 and 80% of the total weight of the skeletal layer. In order to facilitate the opening of the container the container is provided with a tearing mark (9) incorporated in the packaging material, along which the material in the container must be torn to expose a container opening (10) through which the contents of the container are made accessible. The tearing mark (9) consists of an unbroken cut in the skeletal layer or a similar linear recess weakening the material with a depth of penetration of only c. 10-30% of the total thickness of the skeletal layer, which reduces the inherent tear resistance of the skeletal layer by 60-80%. <IMAGE> |
