Coated paper is a composite material that is coated with a layer of PE or PP film on the original paper and coated with plastic particles on the surface of the paper by a casting machine. The main characteristics of composite materials are their ability to prevent oil, water (relatively), and heat bonding. Food grade coated paper is used to package various food packaging papers, including single-layer coated film and double-layer coated film. However, food packaging generally uses single-layer coated film, which means there is a layer of coated film inside. The development trend of the food grade paper coating industry is towards biodegradability: With the introduction of national plastic restrictions, the food grade paper coating industry is gradually shifting from non degradable PE coating to degradable PLA coating.
Raw material factor: The main challenge facing the food grade Coated paper packaging market is that paper cannot package very heavy materials, which leads to the industry being overwhelmed by the polymer and metal packaging industry. In addition, deforestation to obtain raw materials and the release of dioxins during the papermaking process can also cause environmental problems. These factors, in turn, have hindered the growth of the paper packaging market. The R&D and design capabilities still need to be improved: there is an imbalance in the supply and demand of R&D and design talents in the coated paper industry, which cannot meet the personalized needs of users. The design of the Coated paper industry is inconsistent with the market demand, and the design products delivered to consumers are not matched.
