Manufacturing process of a standard photo paper
The core of a standard photo paper is a base paper with a weight between 160-220 gr/m2. This base paper has a PE film applied on the top and on the backside. The PE film on top guarantees a particularly smooth surface as a precondition for the coating and protection against the ink being absorbed by the paper, whereas the backside film enhances the flatness of the paper and in consequence its usability in the printing process.
Already today the core paper, as well as the microporous coating can be processed in a recycling process. The PE film on top and bottom side of the paper is the challenge. Globally, no recycling company can recycle PE-filmed papers as the film is irreversibly attached to the core paper.
