Cup machine in the production and use of paper cups just in line with the national environmental protection policy, using paper cups instead of disposable plastic cups to reduce the "white pollution", the convenience of paper cups and cheap is the key to replace other utensils to widely occupy the market. Paper cups can be divided into cold cups and hot cups according to their uses. The materials of paper cups must not only meet the needs of packaging and processing, but also meet the adaptability of printing. Among many factors in printing technology, the conditions of hot sealing of paper cup processing should be met.
The paper cup material produced by paper cup machine is composed of paper cup base paper directly printing, die cutting, molding processing, surface spray food wax. The production process of hot drinking cup is from paper cup base paper to paper cup paper by doused film, printing, die cutting, molding processing.The paper cup base paper is composed of plant fibers, and its production process is generally through the pulping of plant fibers such as coniferous wood and broadleaf wood, through the pulping of the pulp board, after dreading, grinding, adding chemical auxiliary materials, screening, paper machine copying, etc. The paper cup of the paper cup machine is composed of paper cup base paper and plastic resin particles extruded compound, plastic resin is generally used polyethylene resin (PE), paper cup base paper after doused film single PE film or double PE film becomes single PE paper cup paper or double PE paper cup paper.
PE has its own non-toxic, odorless, tasteless; Reliable health performance; Stable chemical properties; Balanced physical and mechanical properties, good cold resistance; Water resistance, moisture resistance and certain oxygen resistance, oil resistance; Excellent molding performance and good heat sealing performance and other advantages. PE production is large, convenient source, low price, but not suitable for high temperature cooking, if the paper cup has special performance requirements, then the film selection has the corresponding performance of plastic resin.
