Evaluating the Change in Print Quality Due to Liner in Self Adhesive Labels

Self Adhesive Labels have the 4 layered sandwich structure of face paper, adhesive, silicone coating and release liner. The liners act as carriers for the labels throughout the processing stage and come out as clean waste in the label application stage. There is an attempt to replace the glassine paper liner labels with the filmic liner labels as they are lighter and recyclable and compact compared to glassine liners. The aim of the project is to evaluate the print performance of the polypropylene film liner labels in comparison to the glassine paper based labels. The design of experiments is done with relevant print quality parameters for the two label stocks. The response of 2 materials at different levels of important printing factors are found. Study showed similar values with the two liners. The statistical analysis shows no significant change in dot gain by changing the liner hence equal print performance with two materials.
