Friction Coefficient 0.35 BOPP Film Cigarette Package Materials Clear
The commonly used BOPP films include: ordinary type bidirectional tensile polypropylene film heat sealing type bidirectional tensile polypropylene film cigarette packaging film bidirectional tensile polypropylene pearl film bidirectional tensile polypropylene metallized film matting film and so on
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
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,
Features:
1) Waterproof protection.
2) Glossy and Matt both available.
3) Excellent adhesive.
4) High transparency, make the color so beautiful.
5) Enhancing colors and sharpening images.
6) Anti-corrosion, prevent the image from scratching, moisture,
polluted. mildew, yellow etc.
7) Environmental protection.
8) Photos can be kept longer after laminati
