UV Offset Varnish
Introduction
Our UV offset varnish, generally used alone or being mixed for glossing, is widely used for varnishing gold and silver paperboard and various kinds of papers. This gloss oil now owns two new models i.e. UVJ-1# and UVJ-3# that are specially developed by improving the ordinary UV varnish which may generate water spray and conglutination phenomena when the thermal contraction film is heat sealed.
KAISHIMEI UV high gloss varnish comes with no water-spray, no conglutination and non-yellowing but with good glossiness. It is specifically applicable to the post-offset varnishing for cigarette packaging, wine packaging and toothpaste box.
