Firstly, to understand the composition and structure of PE coated paper, it is necessary to understand the composition and structure of the paper. Ordinary paper is composed of wooden fibers with strong water absorption, so everyone knows that ordinary paper absorbs moisture, is afraid of moisture, and has low burst resistance. PE coated paper uses a casting coating machine to apply a layer of PE film on the surface of the paper, which is called PE coated paper. Compared to disposable plastic cups, paper cups are taller and more durable, Various patterns can be printed on the cup body, and the most important thing is that paper cups are more energy-efficient and lightweight, easy to reuse. The biggest difference from plastic cups is that paper cups are easier to degrade and more environmentally friendly.
Classification of PE coated paper
1、 PE single sided coated paper: Single sided coated paper is coated with PE on one side of ordinary paper, which we call single sided coated paper. Common disposable paper cups, hamburger paper, etc. use this type of single sided coated paper;
2、 Pe double-sided coated paper: Double sided coated paper is a type of paper that uses PE coating on both sides of a regular paper. We call it double-sided coated paper;
3、 Pe Sandwich Coated Paper: Sandwich coated paper is a type of paper where PE is coated between two ordinary sheets of paper to form a single sheet, greatly increasing the flexibility of the paper. This type of paper is called sandwich coated paper.
Application of PE coated paper
Pe coated paper is commonly used in food packaging, which can play the role of moisture and oil resistance, and its burst resistance has also been greatly improved. The disposable paper bags, hamburger paper bags, melon seed bags, paper lunch boxes, food paper bags, and aviation Bin bag we see in our daily life are all made of this material in industry, mainly used for moisture insulation and waterproof, and are often pasted on the surface of building materials, Barrier moisture from entering the interior of the board, while PE coated paper is also the main raw material for producing plastic release paper. Coated release paper is generally made of all wood pulp paper, especially in the electronics industry. If straw pulp paper is used, there will be a lot of paper scraps and easily broken edges during die-cutting.
