A process for the production of an oriented plastic film from polyolefins and/or combinations of polyolefins and polyamide, comprising:
- carrying out an extrusion or coextrusion blowing process to create a film;
- and
- carrying out an orientation operation comprising:
- (1) an initial biaxial orientation operation during the blowing process;
- and
- (2) a second orientation operation.
A film produced from polyolefins or combinations of polyolefins and polyamide, the film being produced from a an extrusion or coextrusion blowing process and being oriented by an initial biaxial orientation operation during the blowing process and a second orientation operation.
