1. What is BOPP Laminated WPP Bags?
1.1 About BOPP .
BOPP is the abbreviation of “Biaxially Oriented Polypropylene”, it is a bidirectional stretched Polypropylene film. Its production process is firstly to shape the polypropylene polymer melt as sheets or thick films through a long and narrow panel, then in a special-made stretcher with certain temperature and speed, stretch the material from two vertical directions (machine direction,transverse direction). After the shaping process, some special treatment will be taken on the BOPP film base on its specific application, such as Corona, coating etc. Bopp is widely used as packaging material or printing lamination material. It’s easy to be coated, laminated, and printed with require appearance as a packaging material.

First, a binder is coated on a substrate and dried in a drying tunnel to completely dry the solvent in the binder. In the heated state, the adhesive is melted, another base material is attached thereto, and after cooling, it is cured to produce a composite material with excellent properties. After the bopp film be printed by Gravure printing machines with designs of required, it will be ready to laminate the bopp and wpp fabric together.
1.3 About WPP bags.
