Due to stretching molecular orientation, so this kind of film the physical stability of the air tightness good mechanical strength, high transparency and gloss, tough wear-resisting, is currently the most widely used printing film, generally use thickness is 20 ~ 40 microns, and the most widely used for 20 microns two-way stretch polypropylene film main drawback is that poor heat sealing, so generally used as the outer membrane of composite membrane, such as transparency and polyethylene film composite moisture resistance strength and stiffness of the printing are ideal, suitable for holding food dryingAs the surface of the bidirectional tensile polypropylene film is non-polar, high crystallinity, low surface free energy, therefore, its poor printing performance, ink and adhesive adhesion is poor, before printing and composite surface treatment
