molded paper pulp, also known as PMP, is mainly made from raw materials such as sugarcane residue and bamboo residue, supplemented with waste newsprint, recycled paper boxes, paper box tubes, pure wood pulp and other materials. The materials are processed through pulping and blending to form a certain proportion of thick pulp. The pulp is then made into semi-finished products by vacuum suction and shaping on a special mold, and then dried and hot pressed into various environmentally friendly packaging products.
Molded paper pulp packaging is made from key raw materials such as sugarcane residue, bamboo residue, waste newsprint, and old paper boxes. It undergoes papermaking with a certain ratio and is shaped by a specially designed mold. Afterwards, it goes through a series of product processing procedures such as air drying, heat treatment, shaping and trimming.
Molded paper pulp packaging is recyclable and biodegradable. After being processed with unique processing technology, it has excellent moisture resistance and oil resistance, and can completely replace foam material products, thus completely eliminating "white pollution". The product is environmentally friendly. Molded paper pulp packaging is strongly recommended by the global environmental protection bureau. In its manufacturing process, environmental protection is highly valued, from the use of key raw materials to the end of all processing procedures, the environmental protection awareness is very strong in order to address the problem of three wastes and the harm it poses to environmental protection.
The raw materials for molded paper pulp packaging are sugarcane residue, bamboo residue, waste paper, and more. In the production process, it is mainly a physical reaction, with only a small amount of chemicals used as waterproof coatings. After these chemical raw materials are dried, most of them are preserved in the finished product, without being discharged, thus causing environmental pollution. The production line’s tap water is a closed cycle system. Only water vapor is released indoors during the drying process, and no tap water is needed during the production process. Therefore, the water consumption is also very low.
After many years of development and independent innovation, the technology of molded paper pulp packaging has continuously improved its machine and equipment characteristics and gradually improved its production process. The cost of commodity products has become stable. At present, the cost of paper tray products is basically the same as that of plastic foam products, and some costs are even lower than plastic foam products. The use of paper tray products instead of plastic foam earthquake-resistant products is feasible in terms of performance indicators and product costs. In addition, the environmental protection advantages of molded paper pulp packaging make it a necessary development trend to replace plastic foam products.
