OPP heat sealing film. OPP heat-sealing film is divided into two types: single-sided heat-sealing film and two-way heat-sealing film. It is used for heat-sealing packaging of other electrical components and other products. Divided into two types: single-side heat-sealing and double-side heat-sealing, single-side heat-sealing film is used for general-purpose single-side heat-sealing packaging, and it is also printable.

Mainly used for compounding, printing, bag making, etc. OPP film is a very important flexible packaging material with a wide range of applications. OPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency. The surface energy of OPP film is low, and corona treatment is required before gluing or printing. However, after corona treatment, the OPP film has good printing adaptability and can be overprinted to obtain an exquisite appearance effect, so it is often used as the surface layer material of the composite film.

OPP Heat Seal also has shortcomings, such as easy to accumulate static electricity, no heat sealability, etc. On a high-speed production line, OPP film is prone to static electricity, so a static eliminator needs to be installed. The initial tear strength of the PP film increases after stretching, but the secondary tear strength is very low. Therefore, no cuts should be left on both ends of the OPP film, otherwise the OPP film will be easily torn during printing and lamination. After OPP is coated with self-adhesive, it can produce sealing tape, which is a market with a large amount of OPP.
