ABSTRACT:
The invention relates to a method for the manufacture of packing containers. The container body of the packing container is manufactured by spiral winding of a monoaxially molecular-oriented polyester film. The polyester film is spirally wound onto a mandrel to form a tube with the edge zones of successive turns of the strip overlapping in a continuous joint. The material is sealed within the edge zones by means of surface fusion. The invention also relates to a packing container manufactured in accordance with the method.
