Surface properties of coronatreated polyethylene films containing N-(2-hydroxyethyl) erucamide as slip agent for enhanced adhesion of water-based ink

摘要

In the converting industry, these exist problems of poor printability and poor ink adhesion of waterbased inks onto corona-treated polyolefin films containing conventional slip agents such as erucamide. Slip agents that impart greatly enhanced ink-adhesion as well as good slip property for polyolefins are thus highly desirable, particularly for printing with water-based inks. One such additive that we developed is N-(2-hydroxyethyl) erucamide.
