Comparison of three commonly used plastic protective films

There are many types of plastic protective films, and PE protective film, PVC protective film and ordinary PP film are taken as examples for comparison. PE plastic protective film has the characteristics of transparency, softness, barrier property and mechanical adaptability, high temperature steaming, low temperature heat sealing and so on. It is mainly used as an inner layer substrate for industrial protection, acrylic panels, glass panels and other composite packaging to protect product life and increase aesthetics. It can also be used for the surface layer and compartment of stationery products, as well as auxiliary films, such as loose-leaf pages and labels for photos and collections.

PVC plastic protective film has excellent printing performance, can be combined with paper, PET and other substrates, with high definition and gloss, excellent ink absorption and coating adhesion, high tensile strength, excellent grease barrier properties , low static properties, etc. It is widely used in the field of printing and compounding, and as a packaging material in tobacco and other aspects.

Ordinary PP plastic protective film is simple in process and low in cost, but its optical performance is slightly lower than CPP and BOPP. Mainly used for the outer packaging of snacks, bread, textiles, folders, record sleeves, sports shoes, etc. Among them, PE protective film and PVC protective film have improved composite performance and wider application. After compounding, they have moisture resistance, transparency, stiffness, wide application, and obvious competitive advantages in the industry.www.xmlfilm.com
