What are the differences between pp film and bopp film


What is the difference between pp film and bopp film. Polypropylene (PP, the abbreviation of the initial letter of Poly Propylene in English) is a synthetic resin that was mass-produced in the 1950s. It is a homopolymer of propylene or propylene and α - Copolymers of olefins (ethylene, butene-1, hexene-1), the molecules of which have a linear structure and a density of 0.89 to 0.91 g/cm3, which is lower than that of low-density polyethylene. Because PP has high relative hardness, small specific gravity, high tensile strength, good transparency, good stress crack resistance and chemical resistance, high heat deflection temperature, and excellent injection molding performance, it can be stretched and oriented at will, It can be blended and modified with other materials, so the application range of PP continues to expand, and the demand growth rate is the fastest among the five general-purpose resins, and it has gradually replaced steel, wood, paper, polycarbonate, ABS, PS, nylon, and polyester. and other synthetic materials.
PP film is widely used in printing (labels, etc.), coating, cigarettes and packaging bags for food and agricultural sideline products due to its characteristics of moisture resistance, high mechanical strength, good dimensional stability, light weight, non-toxic, odorless, and good printing performance. , Vacuum aluminum plating, capacitors, etc.

BOPP has high strength, high gas barrier properties, good printing performance and tear resistance. It is the most consumed variety in PP film products, and it is also widely used. Domestic BOPP film products have a certain gap compared with foreign countries in terms of scale and variety. For example, ExxonMobil's annual BOPP film production exceeds 200,000 tons, with nearly 40 varieties, and a wide range of applications. However, the domestic varieties are single, small in scale and high in cost. Therefore, there are still a considerable number of BOPP film products imported from abroad.
