BOPP heat-sealing film, also known as biaxially oriented polypropylene heat-sealing film, is a polypropylene film that has been processed by a biaxially oriented process. It has good physical stability, mechanical strength, air tightness, and high transparency and gloss. In addition, BOPP heat-sealing film also has heat-sealing properties, and can be tightly bonded to other materials under heating conditions, thereby achieving the sealing and fixation of packaging materials.

BOPP heat-sealing film is generally a multi-layer co-extruded film, which is made by co-extruding polypropylene particles into sheets and then stretching them in both the longitudinal and transverse directions. This structure gives BOPP heat-sealing film excellent mechanical properties and heat-sealing properties. Its tensile strength (longitudinal/transverse) is usually greater than 120/200MPa, its elongation at break (longitudinal/transverse) is less than 180%/65%, and its elastic modulus is between 1700~2500MPa. At the same time, BOPP heat-sealing film also has good moisture resistance, transparency and strength, and is suitable for application scenarios such as holding dry food.
BOPP heat-sealing film has a wide range of applications in the packaging industry. It is mainly used in printing, bag making and other processes as the main component of packaging materials. Due to its good heat sealing performance and mechanical strength, BOPP heat sealing film can ensure the sealing and stability of packaging materials, thereby protecting the internal items from the influence of the external environment. In addition, BOPP heat sealing film is also often used to make the outer film of composite film. For example, after being compounded with polyethylene film, its moisture resistance, transparency, strength and printability are further improved, which is suitable for more diverse packaging needs.
Ensure the appropriateness of heat sealing temperature, pressure and time to obtain a good heat sealing effect.
Avoid using BOPP heat sealing film at too high or too low temperature to avoid affecting its performance and service life.
When storing BOPP heat sealing film, it should be stored in a dry and cool environment, avoiding direct sunlight and high temperature.
When choosing BOPP heat sealing film, it should be selected according to factors such as the type, size and weight of the packaged items to ensure the stability and safety of the packaging.
When using BOPP heat sealing film for packaging, attention should be paid to the operation methods and techniques to avoid scratching, tearing or damaging the film.
If the BOPP heat-sealing film needs to be printed or laminated, the surface should be treated first to improve its printing performance and adhesion.
