With the increasing awareness of environmental protection, white waste is gradually reduced. Paper cup machine, in terms of the overall requirements of the product, it adopts the measures of energy saving, consumption reduction, pollution reduction and efficiency improvement. measure.
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 cheapness of paper cups are the keys to replacing other utensils to widely occupy the market. Paper cups are divided into cold drink cups and hot drink cups according to their uses. The material of the paper cup should not only meet the needs of its packaging processing performance, but also meet its printing adaptability. Many factors in printing technology should also meet the conditions of paper cup processing and heat sealing. The following summarizes the material composition of paper cups.
The composition of paper cup material is direct printing, die cutting, forming and processing paper cup base paper, and spraying food wax on the surface. The production process of hot drink cups is to coat the paper cup base paper into paper cup paper, print, die-cut, form and process. The base paper of paper cups is composed of plant fibers. The production process generally adopts plant fibers such as coniferous wood and hardwood, through pulp board disintegration, refining, adding chemical auxiliary materials, screening, paper machine copying, etc. Paper cup paper is composed of paper cup base paper and plastic resin particles extruded and compounded. Polyethylene resin (PE) is generally used for plastic resins.
After the paper cup base paper is coated with single-sided PE film or double-sided PE film, it becomes single-sided PE paper cup paper or double-sided PE paper cup paper. PE itself is non-toxic, odorless and tasteless; reliable hygienic performance; stable chemical performance; balanced physical and mechanical properties, good cold resistance; water resistance, moisture resistance, certain oxygen resistance, oil resistance; excellent molding performance and good heat sealing performance. PE production is large, the source is convenient, and the price is low, but it is not suitable for high-temperature cooking. If the paper cup has special performance requirements, a plastic resin with corresponding properties should be selected when coating the film.
Due to the material of the paper cup, it will save a lot of energy, plus the paper cup production equipment will also carry out certain treatment, will realize the entire production process, in line with national standards, environmental protection and energy saving is a huge contribution.
