Water-based coating: new trend of environmental protection for paper products

01｜Popularity and Limitations of PE Coating
PE coating (polyethylene coating) has been widely used for a long time in disposable paper cups, bowls and other food packaging. It can effectively realize waterproof and oilproof, guaranteeing food safety and usage experience.
However, PE coating also has some problems that cannot be ignored:

• ♻️ Difficult to recycle: traditional PE is tightly bonded to the paper substrate and separation is difficult, resulting in most coated paper products going to landfill or incineration.
• 🌍 Unfavorable degradation: PE belongs to plastic materials, the decomposition cycle in the natural environment is very long, resulting in “white pollution”.
• 📜 Policy restrictions: With the promotion of the global “plastic restriction and plastic ban” policy, many markets are gradually restricting or banning the use of PE coated paper products.

02｜The Emergence of Waterbased Coating

In response to environmental challenges, waterborne coatings are gradually entering the public eye.

As the name suggests, water-based coatings use water-based polymer emulsions and water-based acrylic barrier coatings as the main components, which are coated on the surface of paper using water as the dispersing medium, replacing the PE plastic layer.

Water-based coating has the following core advantages:

– ✅ 100% Biodegradable: high compatibility with paper substrate and can be completely degraded in the natural environment.

– ✅ Highly recyclable: the coating can be separated from the paper during the pulping process, significantly increasing the recycling rate of paper products.

– ✅ Food-grade safety: no harmful solvents and plastic components, meets the EU, FDA and other food contact grade standards.

– ✅ Stable performance: waterproof, oilproof and heat-resistant performance comparable to traditional PE coating.

03｜Industry Trends and Future

As environmental policies and consumer awareness continue to rise, water-based coatings are becoming the mainstream choice for coating paper products. More and more international brands and retailers have gradually replaced PE coating with more environmentally friendly water-based coating solutions.
