Tabre

New techniques for abrasion resistance of printed packaging surfaces, Tabre, was a two-year project to develop methods that can predict what might happen with the surface when the package is subject to strain during transport, and to get a consistent terminology and a form of injury atlas.

Tabre

Challenge: In today’s manufacturing chain, packages are transported long distances. The package is usually manufactured and printed in one factory, and then transported to a packaging plant where the package is filled with its content. The final product is then transported long distances to the consumer. During transport and handling, the package is subjected to various potential causes of damage, both as scratches on the printed surface but also as physical damage on the packaging itself.  This sort of wear and damage cause large economical costs and costs in good-will at the same time as large efforts are made in order to produce an appealing and selling package.
Wear of a surface is a complex phenomenon which depends both of the load onto the surface and the strength of the surface. In addition to the surface strength, the wear of the surface depends thus also on the friction, the friction mechanism and abrasiveness of the counter surface.

Solution: The print disturbances due to wear during transport and handling can be classified into three different categories: removed ink (rub off in Sutherland), scratches and polishing. This classification was shown relevant since samples collected from the field showed similar print disturbances. The occurrences of each of these categories depend to a great extent on the surface structure of the coated substrate. 

Objective: Wear during rub testing with Sutherland and wear during transport simulation differ quite considerably. Rub testing measures the adhesion of the ink onto the surface while print disturbances during transport simulation depended on the plastic deformation due to friction during sliding of two surfaces onto each other.

Partners: The project was financed by EUREKA and had following participating companies together with Innventia: Axeb AB, Falex Tribology, FrontPac, Peterson Packaging, Sony Mobile Communications and Sun Chemical. Rise Bioeconomy’s Thomas Trost was coordinator.
