Basic Information of BOPP Film

Biaxially Oriented Polypropylene (BOPP) is a polypropylene film that has been stretched in both the machine and cross directions. BOPP film production from bopp film manufacturer: put the melt of polypropylene through the narrow head and make into a sheet or a thick film, and then in a dedicated stretching machine under a certain temperature and speed stretch in perpendicular directions (longitudinal and transverse) simultaneously or step-by-step, and after appropriate cooling or heat treatment or a special processing (such as corona, coating, etc.), here comes the thin film. Common BOPP films include common type of biaxially oriented polypropylene film, the heat sealing biaxially oriented polypropylene film, cigarette packaging film, BOPP pearlized film, metallized biaxially oriented polypropylene film, matt film and so on. BOPP film has become one of the most popular, high growth films in the world, such as anti-fog film.

Advantages of BOPP film:



- Excellent clarity
- Good dimensional stability and flatness
- Low electrostatic charge
- Good barrier to water vapor
- High gloss
- Good performance on high speed printing
- Resistant to oils and greases
- Good puncture and flex-crack resistance over a wide range of temperatures
- Not affected by moisture and does not wrinkle or shrink with environmental changes
- Recyclable

Disadvantages



BOPP film has disadvantages, such as easy to be static, without heat sealing. In high-speed operation of the production line, BOPP film is easy to produce static. And you need to install the electrostatic remover. In order to obtain a heat-sealable BOPP film, it can be coated after corona treatment on the surface with the heat-sealable resin glue, such as PVDC latex, EVA latex, etc.; and it can also be coated with a solvent adhesive and applied extrusion coating or the method of production of co-extruded composite heat sealable BOPP film. The film is widely used in the packaging of the bread, clothes, footwear, as well as the packaging of cigarettes, books cover. BOPP film initiator tear strength after stretching improved, but the the secondary tear strength was low, therefore, BOPP films both ends can not leave any incision or it will be easily torn during printing or composition. BOPP coated stickers can produce sealing tape which is the most common market of BOPP.
