ANALISA PELL OFF BAG VINYL PADA MATERIAL LLDPE

Abstract

Vinyl Bag is part of the manufacturing process where its use is for the packaging process. The packaging process generally uses a variety of materials such as EPS, LDPE, LLDPE,HDPE Foam and others, which aims to protect the finished goods of a product from defects. One of the materials used in the packaging process is Linear Low Density Polyethylne (LLDPE). The problem that often occurs during the printing process on HDPE material is pell off where the printing material cannot adhere to the surface of the Vinyl Bag perfectly. In this study, an analysis will be carried out using UV Static Surface on Vinyl Bags before the printing process is carried out. The results of this experiment showed that the printing results on 100% Vinyl Bags had no defects compared to those without the UV Static process, which was 20%. This is caused by the surface of the material that is not smooth and also the unstable structure of the material without UV processing. So that the pell off on the vinyl bag without UV failed 80% of the 15 samples.
