About the flexible packaging raw materials for printing, it is mainly applied to the printing gravure, how many kinds they included, what is their characteristic and application scope?

-PET (Polyethylene)

The biggest characteristic of PET is high application, as the printing layer, it can be laminated with different kinds of barrier layer materials or contact layer materials to constitute a different materials structure, meanwhile, this kind of flexible packaging raw material is suitable for all kind of flexible packaging products with special requirement, such as normal level PET, pasteurized level PET, retorted level PET or matt level PET and etc.

-BOPP (Bi-axial Oriented Polypropylene)

The biggest characteristic of BOPP is high brightness, comparing with PET materials, its application scope is much narrower, for example, as the printing layer, and it is not suitable for the printing of spout pouch or lidding film.

-Printable Nylon (Printable Polyamide)

Its biggest characteristic is high contractility, its application scope is the smallest, and that is only applied to the printing of lidding film.
