What are the raw materials used to produce paper cups
What are the raw materials used to make paper cups? Let’s take a look at how a paper cup machine works. The continuous repetitive motion of the paper cup machine is accomplished by the CAM mechanism in the paper cup machine. The CAM in the CAM mechanism of the paper cup machine rotates and pushes the follower of the paper cup machine to reciprocate according to certain requirements. The CAM structure of the paper cup machine can make the follower of the paper cup machine get more complicated motion rules, so as to realize the circulation effect of the production of cardboard and meet the needs of producing more cardboard products. Toward multifunctional and single high speed polarization. The ultimate goal of paper cup makers is to increase productivity and diversify products. This makes the product specifications of the paper cup machine to the direction of polarization, that is, multifunctional and single high speed.
The production and use of paper cups by paper cup machine is in line with the national environmental policy. Replace single-use plastic cups with paper cups to reduce “white pollution.” Paper cups are divided into cold drinking cups and hot drinking cups according to their purpose. In addition to meeting the needs of its packaging and processing properties, the paper cup material must also meet its printing adaptability. Among the many factors of printing technology, the conditions of paper cup processing and heat sealing must be satisfied.
The paper cup material produced by the paper cup machine consists of direct printing, die-cutting, molding processing and spraying food wax on the surface. The production process of hot drink cup is from paper cup base paper to paper cup paper, printing, die cutting, molding processing. The base paper consists of plant fibers. The production process is generally the use of coniferous wood, broadleaf wood and other plant fibers, after pulping, defibrillating, grinding, adding chemical auxiliary materials, screening, paper machine and other processes, through the pulp board made of paper cup. Cup making machine is made of paper cup base paper and plastic resin particles by extrusion composite. Plastic resin generally adopts polyethylene resin (PE). The base paper is coated with a single-sided PE film or a double-sided PE film to become a single-sided PE cup paper or a double-sided PE film. Paper cup.
PE itself is non-toxic, odorless, tasteless; Reliable hygiene performance; Chemically stable; Balanced physical and mechanical properties, good cold resistance; Water resistance, moisture resistance and certain oxygen resistance, oil resistance; Good thermal sealing performance and so on. PE production, convenient source, low price, but not high temperature cooking. If the paper cup has special performance requirements, should choose the corresponding performance of the plastic resin coating.
