The production and use of the cup machine in the paper cup is in line with the national environmental protection policy. Replacing the disposable plastic cup with the paper cup reduces the "white pollution". The convenience, hygiene and low price of the paper cup is the key to replacing other utensils to widely occupy the market. The paper cup is divided into cold drink cup and hot drink cup according to its use. The material of the paper cup must meet the needs of its packaging and processing performance, as well as its printing adaptability. Among many factors in printing technology, the conditions of heat sealing in paper cup processing should also be met.
The paper cup materials produced by the paper cup machine are composed of paper cup base paper direct printing, die cutting, molding processing, and food wax spraying on the surface. The production process of hot drink cup is to form paper cup paper from paper cup base paper through coating, printing, die cutting and molding. The paper cup base paper is composed of plant fibers. Generally, the production process is to use plant fibers such as coniferous wood and hardwood to pass through the pulp board after pulping, and then loosen, grind, add chemical auxiliary materials, screen and make paper machine. The paper cup of the paper cup machine is composed of paper cup base paper and plastic resin particles. Polyethylene resin (PE) is generally used as the plastic resin. The paper cup base paper becomes single PE paper cup paper or double PE paper cup paper after being coated with single PE film or double PE film.
PE is non-toxic, odorless and tasteless; Reliable sanitary performance; Stable chemical properties; Balanced physical and mechanical properties, good cold resistance; Water resistance, moisture resistance and certain oxygen resistance and oil resistance; Excellent molding performance and good heat sealing performance. PE has large production capacity, convenient source and low price, but it is not suitable for high-temperature cooking. If the paper cup has special performance requirements, the plastic resin with corresponding performance shall be selected for coating.
