What Is BOPP Printing?

In this process, graphics are reverse-printed on BOPP film using gravure technology. The printed film is then laminated onto woven polypropylene fabric.

Why BOPP Bags Are Popular

BOPP laminated bags provide:

High-definition graphics
Glossy or matte appearance
Excellent moisture resistance
Strong branding capability
Better retail shelf presentation

Key Advantages

Photo-quality printing
Better scratch resistance
