HW-PC special sheet surface corona treatment machine for plastic film package

General Introduction

Sheet corona treater is widely used to treat PP, PVC, and metalized polyster laminated sheets to increase surface tension and give better printing and adhesion. Water-based and UV inks printed on plastic films and other substrates create a need for the substreate to be treated prior to printing.
Corona treating is a very effective way to increase the adhesion of virtually any plastic material. Corona treatment increases the surface tension of the sheet / fabrics receptive to inks by inducing molecular chages in the surface of the films / sheets. 

The conventional method of roll-to-roll treatment is standard practice, but in fffset, Sheet corona treatment is required to increase surface tension or improve printability. Some substrates are corona-treated when they are manufactured. Many of these substreates require a surface energy boost to match a pacticular ink or coating. This is done with corona pretreated on the press just prior to the coating application point.

Technical Specification

Applications

Sheet Corona treatment system readily solve surface adhesion problems for a wide variety of products like:

PVC, PP, LD, Foam, Flex, metalized polyester, PE, OPP, and other high-low density plastic materials should particularly be corona treated to enhance the quality of the final product.
