Plasma-treated tubular film

摘要

The single-or multi-layered tubular food casing has an outer layer that is made of plastic, and surface of the outer layer is modified by plasma treatment. The surface of the outer layer is partially coated with color. The color is a radical ultra violet paint. An independent claim is also included for a method for improving adhesion of color coating on a single-or multi-layered tubular food casing.
