What is the BOPP Film?

BOPP FILM

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.

Advantages

1)Good mechanical strength and chemical resistance
2)Good dimensional stability
3)Excellent anti-water
4)Superior optical transparency
5)One or double side heat seal ability
6)Good stiffness
7)resistance to tear and abrasion.

Application

There have huge applications in different area, here list some main usages, for instance:

1)Adhesive Tapes
(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
4)Thermal Lamination
5)Embossing
6)Biscuit/Food Packing,Anti-fog (Food products)
7)Inner wrap
8)Textile Bags

BOPP Film Catagories

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

1:Brueckner

2:ATLAS

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.
