Paper cup processing guide - from paper cup materials to paper cup making

　　From paper cup material to paper cup production how to do more environmentally friendly? Nowadays, due to the strengthening of people's awareness of environmental protection, on the one hand, the whole society advocates clean production, requiring the whole life cycle of products should achieve energy saving, consumption reduction, efficiency; On the other hand, in order to meet the needs of green packaging, packaging products are required to be safe and hygienic, conducive to environmental protection and resource saving. The production and use of paper cups just meet the requirements of environmental protection. Replacing disposable plastic cups with paper cups reduces "white pollution". The convenience, health and low price of paper cups is the key to widely occupy the market instead of other utensils.
　　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 following Hyde paper cup material composition and processing properties for some discussion.

　　Composition of paper cup materials
　　The production process of the cold drink cup is directly printed, die-cut, molded and processed by the paper cup base paper, and the surface is sprayed with 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.
　　Paper cup fan is composed of paper cup base paper and plastic resin particles extruded and compound. Plastic resin generally uses polyethylene resin (PE). Paper cup base paper becomes single PE or double PE paper cup paper after being coated with single-side PE film or double-side PE film. PE has its own non-toxic, odorless, tasteless; 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.

　　Processing properties of paper cups
　　According to the processing performance and using performance of paper cup, Heide experts believe that paper cup base paper must meet the following technical requirements:
　　Strong water resistance: made of paper cup without water seepage, leakage phenomenon.
　　Easy processing and forming: in order to avoid paper jam and wrinkling in the production process, and the paper cup after forming is not easy to deformation, the paper cup base paper is required to be high stiffness, good flatness, appropriate loose thickness, easy processing and forming.
　　Surface fineness of paper: it is required to control the surface roughness value of the printing surface of base paper or PE film to meet the surface fineness of paper cup surface printing requirements.
　　High whiteness: on the premise of not using fluorescent agent, the base paper should maintain the corresponding whiteness of the paper to ensure the clear and beautiful printing pattern.
　　High safety and hygiene: the paper cup base paper and paper cup products are regularly sent to the local national health and epidemic prevention system for safety testing to ensure the safety of users. At the same time, the products (including special plastic particles) also need to be sent to the relevant institutions for testing, in order to ensure that the health and safety to meet the national health standards and meet the requirements of foreign users.
　　
　　Paper cups are food packaging materials that are in direct contact with the population and must meet hygienic standards in terms of hygiene. Hyde proposed that the thermal sealing performance of the continuous molding process of paper cup production and the printing on PE film surface, which requires that the printing technology must be mixed with ink components suitable for the performance of paper cup, moderate drying conditions and other factors. Hyde company has advanced paper cup production line, skilled technical workers and efficient mechanized assembly line, with professional technology to provide customers with high quality and healthy paper products.
