Simultaneous Biaxial Oriented Polyamide film
The first simultaneous BOPA film in the world
Uniform properties of machine direction (MD) and transverse direction (TD)
Excellent processing suitability
- More stable under moisture absorption
- Less S-pattern curling after made into a bag
- Pitch-stable in multi-color printing
- Less front-back miss-alignment after folding
