As the global plastic pollution problem becomes increasingly serious, countries have introduced strict plastic restriction policies to promote the research and development and application of environmentally friendly alternatives. Against this backdrop, the market demand for environmentally friendly paper cups is growing rapidly. Traditional polyethylene (PE) coated paper cups are facing challenges due to recycling difficulties, while biodegradable polylactic acid (PLA) coatings are constrained by high costs and lack of high temperature resistance.
Recently, an emerging water-based coating technology offers a better solution for the food packaging industry. The technology uses environmentally friendly water-based coatings, which not only effectively solves the leakage problem, but also has excellent heat resistance, adhesion and media resistance to meet the needs of hot beverage serving. Compared with traditional PE lamination, water-based coated paper is easier to recycle and repulp, truly realising the environmental goal of ‘recycling and non-pollution’.
Industry experts said that the breakthrough in water-based coating technology for the sustainable development of the food packaging industry provides a new direction, not only in line with international plastic policy requirements, but also help enterprises to enhance green competitiveness. In the future, with the further maturation of the technology, water-based coating may become a mainstream alternative to plastic lamination, helping the global process of ending plastic pollution.
