What are the advantages and applications of BOPP film

Advantages of BOPP film:

The surface energy of BOPP film is low, and corona treatment is required before gluing or printing. After corona treatment, BOPP film has good printing adaptability, and can be overprinted to obtain beautiful appearance effect, so it is often used as the surface material of composite film.

Disadvantages of BOPP film:

BOPP film also has shortcomings, such as easy to accumulate static electricity, no heat sealing, etc. In the high-speed production line, BOPP film is easy to generate static electricity, so it is necessary to install static electricity remover. In order to obtain the heat-sealable BOPP film, the heat-sealable resin glue, such as PVDC latex, EVA latex, etc., can be coated after the surface of the BOPP film is corona treated, and the solvent adhesive can also be coated. The heat-sealable BOPP film can also be produced by extrusion coating or co-extrusion composite method.
BOPP film is widely used in the cover packaging of bread, clothing, footwear, cigarettes and books. The initial tear strength of BOPP film is improved after stretching, but the secondary tear strength is very low. Therefore, no notch can be left on both ends of BOPP film, otherwise BOPP film is easy to tear when printing and laminating. After BOPP is coated with self-adhesive adhesive, box sealing adhesive tape can be produced, which is a market with a large amount of BOPP.
