Transparent Plastic BOPP PE PET CPP Film Rolls

BOPP biaxially oriented polypropylene film (BOPP film for short) is a new excellent transparent soft packaging material. It is a crystalline polymer product. After biaxial stretching, due to the role of molecular chains, the crystallinity increases, which significantly improves the tensile strength, elastic modulus, impact strength, tear strength, flexural strength and other properties. It has good transparency, luster, moisture resistance, and also has the advantages of light texture and relatively low price. BOPP film is suitable for all kinds of packaging, printing, composite, aluminum plating, etc.

PET film, namely polyethylene terephthalate film, is widely used in packaging and textile. The following is the academic explanation: pet is polyethylene terephthalate, with the chemical formula of - OCH2-CH2OCOC6H4CO - English name: polyethylene terephthalate, abbreviated as PET, is a high polymer, which is derived from the dehydration and condensation reaction of ethylene terephthalate. Ethylene terephthalate is obtained by esterification of terephthalic acid and ethylene glycol. PET is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range. Its long-term use temperature can reach 120 ℃, and its electrical insulation is excellent. Even under high temperature and high frequency, its electrical performance is still good, but its corona resistance is poor, creep resistance, fatigue resistance, friction resistance, and dimensional stability are good.
