According to related reports, my country's annual use of disposable water cups has reached 20 billion. With the change in the concept of replacing plastic with paper, paper cups are consumed more and more. This poses great challenges to the environment and resource recycling.

In order to achieve the effect of isolation from food, a coating layer is usually added to the inner wall in the production of paper cups. At present, most of the coating layers of paper cups on the market use PE film. If the material used is not good or the processing technology is not good enough, harmful substances will be produced. There are often cases of paper cups being recalled because the quality of the coating layer is not good enough.

Most people think that paper cups are more environmentally friendly than plastic cups. Although disposable paper cups are made of cellulose and are renewable, paper cups using PE film can only be regarded as non-recyclable products technically, because PE film will hinder the fiber of paper cups.的degradation. Therefore, the recycling rate of disposable paper cups is actually very low. However, the water-based heat sealant developed by Mitsui Chemicals of Japan can be used for paper cups, paper bowls, and paper packaging. It replaces LDPE/PLA/PBS coating and realizes no plasticization of paper containers. The product does not contain organic solvents and halogens, is odorless, dries quickly after coating, and has high heat sealing strength. The most important thing is that the product can be recycled directly into paper, can degrade compost, has very good water and oil resistance, and can adjust the air permeability according to the number of coatings and the amount of coating.

In the application of paper coating, Mitsui Chemicals has specially developed this water-based heat sealant S300, which not only provides a new compostable material for packaging that may be contaminated by food residues, but also provides a choice for paper recycling. It can still maintain stable performance at high temperatures, and has good barrier properties to liquids, fats and odors. With such a cup, you can safely have a cup of hot milk tea in winter
