Environmentally friendly pulp molded products are a fast new packaging material in recent years and an excellent substitute for wood. Pulp molded products currently adopt the manufacturing process of raw material beating-ingredients-molding forming-drying-finalization, which contains and protects the packaged products, which is convenient and practical.
At present, environmentally friendly pulp molded products are mainly used in industrial product inner packaging, poultry egg trays, fresh fruit trays, food and semi-finished products packaging, medical device packaging, special products such as children's toys, drama props, handicraft blanks, furniture, parts, etc. Materials, military industry, clothing and other industries packaging, etc. Pulp molded products are generally processed by combining multiple sets of molds. With the improvement of mold technology, it is now possible to produce cavity-type pulp molded products. Such molded pulp products are mostly used as containers or decorations. The combined processing mode is to realize a certain application requirement by combining multiple pulp molded bodies of different shapes during forming, and complete the required packaging function. In foreign countries, disposable pulp molded urinals have replaced multiple-use urinals made of polyester materials. Therefore, with the improvement of mold technology, the structure of pulp molded products is becoming more and more complicated and detailed.
With the increasing demand for environmental protection and packaging reduction in recent years, as well as the further improvement of electromechanical technology, the structure of cushioning materials has been developed rapidly, and cushioning materials with different structures and suitable for special products and their structures have emerged. . The structure of cushioning materials has changed from a single type to a complex type, and from a process type to a functional type. Paper honeycomb has developed from a traditional structural change to an innovation in the molding process; corrugated cardboard has also changed from a single corrugated structure to a corrugated composite structure; with the further improvement of mold technology, pulp molded products have become more detailed and complex.
