The paper cup machine is composed of paper cup base paper and plastic resin particles extruded and compounded. 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 is non-toxic, odorless, and tasteless; reliable hygienic performance; stable chemical properties; balanced physical and mechanical properties, good cold resistance; water resistance, moisture resistance, and certain oxygen and oil resistance; excellent molding performance and good heat sealing performance. PE has large production volume, convenient sources, and low prices, but it is not suitable for high-temperature cooking. If the paper cup machine has special performance requirements, plastic resins with corresponding performance are selected during coating.
The production process of cold drink cups is that the paper cup machine directly prints, die-cuts, and forms, and the surface is sprayed with food wax. The production process of hot drink cups is that the paper cup machine is coated into a paper cup machine, printed, die-cut, and formed.
Paper cup machines are made of plant fibers. The production process is generally to use softwood, hardwood and other plant fibers through pulping pulp board after demulsification, grinding, adding chemical auxiliary materials, screening, paper machine making, etc. Direct printing paper cup machines should have a certain surface strength (wax stick value ≥ 14A) to prevent hair loss and powder loss during printing; at the same time, they must have a good surface fineness to meet the uniformity of ink on the printed products.
