What materials are needed to produce paper cups

With the strengthening of national environmental awareness, on the one hand, the whole society advocates clean production and requires that the entire life cycle of products should realize energy-saving, consumption-reducing, pollution-reducing, and efficiency-enhancing measures; on the other hand, in order to meet the needs of green packaging, packaging products are required to be safe and hygienic, have good adaptability to environmental protection, and can save resources.

The production and use of paper cups are in line with the national environmental protection policy. Replacing disposable plastic cups with paper cups reduces “white pollution”. The convenience, hygiene and low price of paper cups are the key to replacing other utensils to occupy a wide market.Paper cups are divided into cold drink cups and hot drink cups according to their purpose. In addition to meeting the needs of their packaging and processing performance, the materials of paper cups must also meet their printing adaptability.Among the many factors in printing technology, the conditions for heat sealing of paper cup processing must also be met.

Composition of paper cup material
The production process of cold drink cups is directly printed, die-cut, molded, and double-sided laminating from the base paper of the paper cup.The production process of hot drink cups is from the base paper of the paper cup to the paper cup paper, printing, die-cutting, and forming processing.

Paper cup base paper composition
The base paper of the paper cup is composed of plant fibers. The production process is generally to use coniferous wood, broadleaf wood and other plant fibers to pass through the pulp board after pulping, dredge, grind the pulp, add chemical accessories, screen, and copy the paper machine.

Composition of paper cup paper
Paper cup paper is composed of paper cup base paper and plastic resin particles extruded and composite. Polyethylene resin (PE) is generally used for plastic resin. The paper cup base paper becomes single PE paper cup paper or double PE paper cup paper after laminating single-sided PE film or double-sided PE film.PE has its own non-toxic, odorless and odorless; reliable hygienic properties; stable chemical properties; balanced physical and mechanical properties, good cold resistance; water resistance, moisture resistance and certain oxygen resistance, oil resistance; excellent molding performance and good heat sealing performance and other advantages.PE has a 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, a plastic resin with corresponding performance is selected for laminating.

Requirements for paper cup substrate
Surface requirements of paper cup base paper
The base paper of the directly printed paper cup should have a certain surface strength (wax rod value ≥14A) to prevent hair loss and powder loss during printing; at the same time, it must have a good surface fineness to meet the uniformity of inking of the printed matter.
