Introduction of Biaxially Oriented Poly-propylene: Basic Knowledge and Its Application on Industry Arief Koeswanto

Polypropylene is an attractive candidate material for packaging applications because of its low cost and good thermal stability. Commercial polypropylene films are typically oriented by a tentering process in which an extruded film is quenched, reheated, and biaxially drawn into a film. Orientation improves both the mechanical and gas-barrier properties of the films. To achieve appropriate knowledge of this product, a fundamental understanding of each portion of the BOPP, is required.
