The molded fiber of pulp molding is made of recycled paper or fiber, it is 100% recyclable and biodegradable, and the use of green packaging will be an inevitable global trend, and pulp molded products are known for their Good performance, especially excellent environmental protection properties.
Pulp molding is a three-dimensional papermaking technology, which means that a certain concentration of pulp is added with an appropriate amount of chemical additives, and the fibers are evenly distributed on the surface of the mold by vacuum or pressure in the molding machine, so as to make a wet paper mold blank, and then further dewatering and dehydration. Mold, drying and shaping the product, and the production technology of pulp molding product. Products produced from different compositions of waste paper have different properties.
Therefore, according to the use of the product, different waste papers or several kinds of waste papers can be used in combination to obtain better economic benefits and performance. Pulp molded products can be designed to improve their structure, and materials or surfaces with various components are added during production to achieve the required performance and characteristics for a certain item or under certain conditions. In addition, the characteristics of the paper molds obtained by different processing methods are different, so changing the processing methods or techniques can improve the performance of the paper molds.
Advantages of pulp molding: the raw material is waste paper, including cardboard, waste paper box paper, waste white edge paper, etc., which have a wide range of sources; the production process is completed by pulping, adsorption molding, drying and shaping, which is harmless to the environment; it can be Recycling and recycling; the volume is smaller than that of foamed plastic, it can be overlapped, and the transportation is convenient. Pulp molding, in addition to lunch boxes and tableware, is also used for industrial buffer packaging, and is currently developing rapidly.
