The production and use of paper cup machines in paper cups is in line with the national environmental protection policy. Using paper cups to replace disposable plastic cups reduces "white pollution". The convenience, sanitation and low cost of paper cups is the key to replacing other utensils in the market. Paper cups are divided into cold drink cups and hot drink cups according to their uses. In addition to meeting the requirements of packaging processing performance, the material of paper cups must also meet its printing adaptability. In many factors in printing technology, the heat-sealing conditions for paper cup processing must also be met.
The composition of the paper cup material produced by the paper cup machine is direct printing of the paper cup base paper, die-cutting, forming processing, and spraying food wax on the surface. The production process of the hot drink cup is by laminating the base paper of the paper cup into paper cup paper, printing, die-cutting, and forming processing. The paper cup base paper is composed of plant fibers, and its production process is generally to use coniferous wood, hardwood and other plant fibers to pass through the pulp board after pulping, decomposing, refining, adding chemical auxiliary materials, screening, papermaking and so on. The paper cup of the paper cup machine is composed of paper cup base paper and plastic resin particles extruded and compounded. The plastic resin is generally polyethylene resin (PE). After the paper cup base paper is coated with a single-sided PE film or a double-sided PE film, it becomes a single PE paper cup paper or double PE Paper cup paper.
PE has its own non-toxic, odorless and tasteless; reliable hygienic properties; stable chemical properties; balanced physical and mechanical properties, good cold resistance; water resistance, moisture resistance, and certain oxygen and oil resistance; excellent molding properties and very good The heat sealing performance and other advantages. PE has a large production volume, convenient source and low price, but it is not suitable for high-temperature cooking. If the paper cup has special performance requirements, plastic resin with corresponding performance should be used when coating the film.
