ABSTRACT:
A light weight packaging container, similar to a capsule and made by deep-drawing and/or stretching of a multi-layer foil composite, is composed of synthetic material and aluminum. An aluminum layer or foil having a thickness within the range of from one grain to a few grains is provided. At least one layer of synthetic material is fixed to the aluminum layer or foil. The total thickness of the synthetic layer or layers is substantially greater than that of the aluminum layer or foil. In one embodiment, only one layer of synthetic material is provided. In another embodiment, two layers of synthetic material are provided, one being fixed to one major surface of the aluminum layer or foil and the other being fixed to the other major surface of the aluminum layer or foil.
