The paper cup machine is composed of paper cup base paper and plastic resin particles extruded and compounded. The plastic resin generally uses polyethylene resin (PE). The paper cup base paper is coated with a single-sided PE film or a double-sided PE film to become a single PE paper cup machine or a double PE paper cup machine . 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 machine has special performance requirements, plastic resin with corresponding performance should be used when laminating.
The production process of cold drink cup is directly printed by paper cup machine, die-cutting, forming processing, and spraying food wax on the surface. The production process of the hot drink cup is a paper cup machine through a paper cup machine, printing, die cutting, and forming.
The paper cup machine 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. Direct printing paper cup machines should have a certain surface strength (wax stick value ≥14A) to prevent lint and powder during printing; at the same time, they must have a good surface fineness to meet the uniformity of inking of the printed matter.
