BOPP film is a widely used flexible packaging material.BOPP plastic film is colorless, odorless, tasteless and non-toxic, with high tensile strength, impact strength, stiffness, strong toughness and good transparency. When using BOPP films, proper handling and precautions are essential to ensure the quality and safety of product packaging. This guide will provide you with a detailed overview of the important things you need to be aware of when using BOPP films to help you package and use them effectively.
Commonly used BOPP films include: general-purpose biaxially oriented polypropylene film, heat-sealed biaxially oriented polypropylene film, tobacco packaging film, biaxially oriented polypropylene pearlescent film, biaxially oriented polypropylene metalized film, matte film and so on.
What should I pay attention to when using BOPP film
1、The use of the protective film should pay attention to the tensile and ductility. Some protective films have weak stretchability, if you do not pay attention to the use, it will shorten the service life of the film.
2、Aluminum profile type objects, after polishing should use low viscosity goods. The oxidized surface should ensure that there are no holes and leaks, otherwise it is easy to be left behind.
3、BOPP film is not resistant to high temperature, so it can not be pasted on high temperature objects above 150℃.
4、Because plastic objects contain many plasticizers, tougheners, film removers and other components, they should be tested before batch use to make sure there is no alienation reaction.
5、BOPP film is sensitive to ultraviolet rays, and prolonged exposure to sunlight may result in yellowing, aging or loss of elasticity of the film. Therefore, during use and storage, direct sunlight should be avoided as much as possible, choose a cool and dry environment to store and use the film.
6、BOPP film has strong electrostatic properties, easy to adsorb dust and impurities. In the process of use, attention should be paid to the control of static electricity, you can use anti-static equipment or add anti-static agent to reduce the interference of static electricity on the packaging process.
7、In the use and storage process, be sure to avoid film moisture, especially in high humidity seasons or regions.
8、Regular inspection of the quality and condition of the BOPP film is to ensure that the packaging effect and product safety is the key. Pay attention to check whether there are bubbles, cracks or foreign objects on the surface of the film, and detect and deal with problems in time to ensure the quality of packaging.
Conclusion
These eight aspects are what we must pay attention to when using this BOPP film. Through proper use and maintenance, BOPP film can be used more safely and effectively for packaging and encapsulation to ensure product quality and safety.
