Wuhan University successfully developed a new type of tipping paper varnish

In recent years, the tipping paper has been greatly developed and innovated in terms of functions and uses. The use of tipping paper by tobacco plants is not limited to pure packaging, but also focuses on its decorative effect. For this reason, higher requirements are placed on the printing aesthetics of tipping paper. Because the tipping paper has direct contact with the smoker, the printing ink and coating of the tipping paper must be non-toxic and meet the food hygiene requirements.

To solve this problem, the printing and packaging department of Wuhan University used its own advantages to conduct in-depth research, and finally successfully developed a healthy and environmentally friendly new product - cigarette holder with water pine paper varnish. The product is an alcohol-soluble varnish that is modified and compounded by a variety of imported resins. After being polished, the cork paper showed better gloss, smoothness and abrasion resistance, and had a certain degree of water resistance and wet strength, especially its hygienic and non-toxic, in line with national food hygiene requirements.
