Biaxially oriented polypropylene film (BOPP) has a history of more than 35 years, and is now widely used in many industries such as paper packaging, printing, lamination and film packaging. ...
Two-way orientation is the process of stretching the PP film in two directions. This orientation influences and changes the properties of the membrane, making the PP membrane more difficult to deform, more tough, more rigid, more transparent, and more resistant to osmotic gas / water.
The process of BOPP film production is usually through the following steps:
- Extrusion / blowing film
- Orient the membrane in two directions
- Cutting film / rolls
- Metal coating, or split 2 (if available).
With good properties such as smooth, transparent, lightweight and easy to print, BOPP films have become an indispensable material and widely used in many agricultural and industrial applications such as packaging. , food, weaving yarn, textile dyeing, printing, stationery ...
