Application：Used for lamination and bag-making .
*Hight tensile strength *High matt property
*Excellent ink and coating adhesion *Excellent separation from oil
Application：Used for printing and bag-making
The film production is a continuous process. In most cases, it is a co-extrusion process.The base polymer and additives are fed by a continuously operating feeder. A further cost efficient alternative is gravimetric feeding of additive powder, directly into a twin screw feeder for optimal dispersion.
Actually, the threshold of producing bopp film is very high. Firstly, the production line is very expensive (USD20-30 Million/line). Second, running and maintenance cost is also high. If small enterprise, it’s hard to do this production.
In addition,here I recommend two famous company which are best solution for this film production. Just for reference
Moreover,Mostly Chinese BOPP film manufacturers are using their production line. Such as, Gettel Group .They are one of biggest film manufacturer in the world.
