BOPP Film Introduction
BOPP Film is a abbreviation of Biaxially Oriented Polypropylene Film .It is extruded from plastic granulate(Polypropylene) and stretching polypropylene film, in both lengthways and transverse direction. Due to the change in morphology of the molecular structure,therefore, the films acquire a wide variety of good properties.Such as, transparency,durability etc.Therefore widely use in different area,for instance food packing, tapes,electronics etc.
1)Good mechanical strength and chemical resistance
2)Good dimensional stability
4)Superior optical transparency
5)One or double side heat seal ability
7)resistance to tear and abrasion.
There have huge applications in different area, here list some main usages, for instance:
(use this bopp film as substrate,and,water based acrylic adhesives ,after that, use bopp tape coating machine to make adhesive tapes)
2)Packaging & Conversion
3)Printing and Lamination
6)Biscuit/Food Packing,Anti-fog (Food products)
BOPP Film Catagories
1 BOPP Film use for adhesive tape
*Hight transparenct and gloss *Good separation from steam
*High tensile strength *Excellent ink and coating adhesion
*Excellent size stability
Application：Used as substrate for adhesive tape
2 BOPP Film for normal bag packing
*Hight transparency and gloss *Excellent separation from oxygen and oil
*Excellent mechanical property *Excellent ink and coating adhesion
*Low Static surface *Excellent evenness
Application：Used for lamination and bag-making .
3 Printing Matt Film
*Hight tensile strength *High matt property
*Excellent ink and coating adhesion *Excellent separation from oil
Application：Used for printing and bag-making
BOPP film production
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.
