Pulp pallet packaging is the use of waste paper, pulp, cane pulp and other fibers as raw materials, through the molding of three-dimensional paper materials, because of its good performance and environmental protection, is now widely used, the following is to introduce the development history of paper pallet packaging: The paper holder technology and the first product was developed in Denmark as early as the 1960s and could be automated assembly line production, but it was not widely used at that time.

Until plastic packaging in daily production and life caused a lot of white pollution, the market is in urgent need of a new type of environmental protection packaging materials, paper packaging has been paid attention to, at present European and American countries have developed and promoted this technology, driving the development of paper packaging industry. With the maturity of the production process, the paper holder can be widely produced in large quantities, but in the paper holder production process, drying is a very important process, and occupies a larger production cost, then how to improve the drying efficiency of the paper holder?

The raw material of the pulp bracket is only about 1% of the pulp of the paper fiber. After forming the wet paper page, the water content of the wet paper page should be reduced to 55% by mechanical pressing, and the water content of the paper bracket after forming is as high as 65% to 75%. It is difficult to reduce the water content by mechanical method. In the production process of paper support, each kilogram of paper support finished products through the drying process to remove about 3.5-4.5KG of water, whether from reducing production costs or improving the quality of paper support, improve the drying efficiency is of great significance!

The wet paper mold with paper fiber as the main component is a porous object with capillary structure inside, and the water exists between the surface of the fiber and the pores of the fiber capillary. Pulp supporting products used for internal packaging are generally required to have good dynamic buffering performance, in which the moisture can not be completely removed by mechanical pressing, but need to be removed by drying. Therefore, compared with the conventional paper drying process, the drying strength of pulp molding products is very high.

Hot air, on the one hand, acts as a heat source to provide energy for removing water; on the other hand, it acts as a water carrier to carry away the water that constantly evaporates. The water in the wet press paper holder depends on the internal and external diffusion of water. The so-called internal diffusion refers to the migration process of water from the inside to the outer surface in the wet paper holder, and the external diffusion refers to the process of water being taken away after evaporation from the surface. Paper bracket dry rate depends on the moisture inside, outside the diffusion rate and the balance between the two coordination, reasonable process conditions should be around the above two aspects and paper bracket products dry physical properties to develop!

While the development of our paper supporting industry has started relatively slowly, the paper supporting industry has been introduced and learning the foreign technology in the process, so the paper supporting industry has developed rapidly, and the number of paper supporting manufacturers in the market has been increased greatly. And with the progress of technology, paper holder as well from the past simple of low-grade products, such as eggs, fruit, beer bottles, gradually to develop in the direction of the inner product packaging, paper asked by virtue of environmental protection, the buffer material, anti-static and moisture-proof performance, also can open mould according to the requirements of all kinds of paper packaging, so the enterprise in the field of different industries, Become a good choice for product packaging!
