Introduction To BOPP Film

BOPP film, also known as biaxially oriented polypropylene film, is an important flexible packaging material with a wide range of applications and remarkable characteristics. BOPP film occupies an important position in the packaging field with its colorless, odorless, tasteless, non-toxic characteristics, as well as high tensile strength, impact strength, rigidity and toughness. Although BOPP film has poor heat sealing properties, it is often used as the outer layer of composite film. After being compounded with polyethylene film, it can significantly improve moisture resistance, transparency, strength, stiffness and printability. The two surfaces of BOPP film have an asymmetric design with different properties, high stiffness, low static electricity, high gloss, high transparency and low haze. The packaging effect is flat and beautiful, and the special surface treatment can effectively prevent undesirable phenomena such as card machine sticking to the packaging. Because the film quality is stable, it can effectively improve efficient production capacity with automatic machine packaging. BOPP film has a wide range of uses, such as food packaging, daily necessities packaging, industrial applications, etc. 1. Food packaging: BOPP film is often used in food packaging, such as candy, tea, juice, milk, etc. Due to its moisture resistance and transparency, it is suitable for holding dry food. 2. Daily necessities packaging: BOPP film is also used for packaging daily necessities, such as soap, cosmetics, pharmaceutical products, etc. Its surface treatment technology such as corona treatment can improve its printing performance, making it suitable for a variety of printing methods. 3. Industrial applications: BOPP film is also widely used in industry, such as for making tape base film, composite materials for books and cartons, etc. 4. Other applications: In addition to the above applications, BOPP film is also used for textile packaging, vegetable and fruit fresh-keeping packaging, etc. 5. Special uses: With the development of technology, the application range of BOPP film continues to expand, including antistatic film, smooth film, shrink film, laser film, heat-sealed film, matte film, pearlescent film, anti-fog film, etc. These special films perform well in packaging, labeling, anti-counterfeiting, etc. In summary, BOPP film is widely used in many fields such as food, daily necessities, industrial products, etc. due to its excellent physical stability, mechanical strength, transparency and good moisture resistance, and has become an indispensable part of modern packaging materials.
