The paper cups are divided into cold drink cups and hot drink cups according to the purpose. In addition to satisfying the packaging processing performance, the paper cups must also meet the printing adaptability. In the printing technology, many factors must also meet the conditions of heat sealing of paper cup processing.
The paper cup material produced by the paper cup machine is composed of paper cup base paper directly printed, die-cut, molded, and surface sprayed with food wax. The production process of the hot drink cup is made by laminating the paper base paper into paper cup paper, printing, die cutting and forming. The paper cup base paper is composed of plant fibers. The production process is generally carried out by using plant fibers such as softwood and broadleaf wood through pulping after pulping, refining, adding chemical auxiliary materials, screening, paper machine making and the like. The paper cup of the paper cup machine is composed of paper cup base paper and plastic resin particles. The plastic resin is generally made of polyethylene resin (PE). The paper cup base paper is single-sided PE film or double-sided PE film to become single PE paper cup paper or double PE. Paper cup paper.
PE has its own non-toxic, odorless, tasteless; hygienic performance is reliable; chemical properties are stable; physical and mechanical properties are balanced, cold resistance is good; water resistance, moisture resistance and certain oxygen resistance, oil resistance; excellent molding properties and good Advantages of heat sealing performance
