Pulp molding is a kind of three-dimensional paper technology. It with waste paper as raw material, on the mould machine in a certain shape by the special mould produce paper products. It has four major advantages: raw material for paper, including the board paper, paper wastebasket, waste white paper, such as sources; Its production process by pulping and adsorption molding, drying, finalize the design process is complete, harmless to the environment. Can be recycling use; Volume is smaller than foamed plastics, can overlap, the transportation is convenient. Molded pulp, except for boxes, tableware, more do cushion packaging industry, is now developing very quickly.

Including the egg tray, fruit tray. It is a waste paper as raw material, add some chemicals, according to different purposes, and then produce a variety of products, in the shape of a used as eggs, fruit, precision devices, easy to break the fragile glass, ceramics, handicraft packing liner, has the good buffer protection performance. Production of paper pulp molding technology and equipment development soon, the basic process is slurry preparation, molding, forming, drying, plastic four working procedure.

Molded pulp products is rapidly in recent years, new packaging materials, is a good substitute for wood. Beating pulp molding products currently USES: raw materials, ingredients, molding, drying, finalize the design manufacturing process. Because after molding, workpieces with plenty of water (about 55-60%), the moisture content of the final products of 12-14%, therefore in the drying process of the workpiece to remove moisture of workpiece weight average, all must depend on this part of the water absorption of heat into steam to take off. Due to the phase transformation in the drying process, energy consumption is very large, paper pulp molding products processing become energy-intensive products. To this end, the drying process of energy conversion, the thermodynamic analysis is very necessary. Because, through the analysis of drying equipment design process improvement, improve the utilization rate of energy and to reduce the production cost of molded pulp products industry has important guiding significance.

Is the function of paper pulp molding products: tolerance and protection of packaged products, convenient and practical.

Tolerance and protection is the first function of molded pulp products packaging products. Molded pulp products should be able to reliable for packaging of packaged products, packaged products in the transportation, loading and unloading, and use process from being damaged, and its strength, stiffness and stability requirements. Molded pulp products used materials of packaged product is safety, both do not interact.

Easy to use the appropriate human structure should be molded pulp products. Molded pulp products should not harm the human body structure and shape, in use process to adapt to the operation and handling of the body.

Then, paper pulp molding products are through its own special structure in loading modified to extend the corresponding time, absorb energy, thereby reducing packaging of shock and vibration. It is different from the cushioning mechanism of the foam plastic packaging products, because of the foam products, with a large number of compressible materials due to the internal distribution of bubble hole, no matter why products shape, it has good buffer performance, if use the pulp plastic membrane materials and foam respectively made a big plane, the former is obviously to buffer, and the latter is not cushion, so for the pulp plastic film products, good structural design is within its complete protection, improve the damping capacity in the process of transportation and handling of basic guarantee. Design the structure of the performance will directly affect the strength, stiffness, stability and practicability of the package, namely the structure of the paper pulp molding products directly affect the realization of the function of the packaging.
