What are the application areas of paper molds? Paper mold is a kind of paper mold. Its function is very powerful, and it can prevent the load from moisture and shock. The application field of paper mold is very wide. Next, let’s talk about paper mold. What are the application areas.
Paper mold is a three-dimensional papermaking technology. It uses waste paper as raw material, and a special mold is used to mold a certain shape of paper product on a molding machine. It has four major advantages: The raw material is waste paper, including board paper, waste carton paper, waste white edge paper, etc., with a wide range of sources; its production process is completed by pulping, adsorption molding, drying and shaping, etc., which is not harmful to the environment; It can be recycled and reused; the volume is smaller than that of foamed plastic, it can be overlapped, and the transportation is convenient. Paper molds, in addition to lunch boxes and tableware, are also used for industrial cushioning packaging, and they are currently developing very rapidly.
Including egg boxes, egg trays, fruit trays, flower pots, disposable bedpans, etc. It uses waste paper as raw material, adds some moisture-proofing agent (aluminum sulfate) or water-proofing agent, and then makes various shapes of model products according to different uses, which are used as eggs, fruits, precision devices, and fragile glass. , Ceramic products, handicrafts, etc. packaging liner, with good cushioning and protection performance. The production of paper mold technology and equipment has developed rapidly. The basic process is slurry preparation, molding, drying, and shaping. Domestic equipment is mainly semi-automatic equipment, while foreign countries are mostly fully automatic high-energy-consuming assembly lines;

Paper molded products are a new type of packaging material that has been rapid in recent years and an excellent substitute for wood. The paper molded product adopts the manufacturing process of raw material beating-ingredients-compression molding-drying-shaping. Since there is a lot of moisture (about 55-60%) left on the workpiece after compression molding, the moisture content of the product is 12-14%, so during the drying process of the workpiece, the moisture that accounts for the weight of the workpiece should be removed. This part of the water is all removed by absorbing heat and turning into water vapor. Due to the phase change in the drying process, the energy consumption is very large, and the paper molded products are processed into high energy consumption products. For this reason, it is very necessary to conduct a thermal analysis on the energy conversion process of its drying. Because, through analysis, the design and processing of drying equipment can be improved, and the energy utilization rate can be improved, which has very important guiding significance for reducing the production cost of the paper molded product industry.
Paper molded products are solid containers used to contain and limit the contents to be packaged, and serve the circulation, storage, and transportation of commodities, that is, they are mainly used in the transportation and packaging of commodities.
The function of the paper molded product is to contain and protect the packaged product, which is convenient and practical.
To contain and protect packaging products is the primary function of paper molded products. The paper molded product should be able to reliably contain the packaged product specified by the package, so that the packaged product is not damaged during transportation, loading, unloading, and use, and it should meet the requirements of strength, rigidity and stability. The materials used in paper molded products are also safe for the packaged products, and the two do not interact. The structure of the paper molded product that is easy to use should be pleasant. The structure and shape of paper molded products should not harm the human body, and adapt to the operation and handling of the human body during use.
In addition, the paper molded product uses its special structure to deform when loaded to prolong the corresponding time and absorb external energy, thereby reducing the impact and vibration of the packaged object. It is different from the cushioning mechanism of foam plastic packaging products, because foam products have a large number of compressible cells distributed inside the material, regardless of the shape of the product, it has better cushioning performance, if paper pulp plastic film materials and Foam plastics are made into a large plane. Obviously, the former can be cushioned, while the latter cannot be cushioned. Therefore, for pulp-plastic film products, a good structural design is to complete the protection of the contents and improve it during transportation and handling. The basic guarantee of shock absorption capacity. The designed structural performance will directly affect the strength, rigidity, stability and practicability of the package, that is, the structure of the paper molded product directly affects the realization of its packaging function.
