Introduction to Pulp Molding

The packaging demand for molded pulp for eggs accounts for approximately 75% of the market share, with an expected compound annual growth rate of 5.1% by 2027. Pulp molded products are molded products of various shapes made for different purposes, mostly as auxiliary and protective materials for various products. They generally include cushioning packaging materials, pulp molded agricultural products, pulp molded products, disposable tableware, etc.

Pulp molded products are solid containers used to hold and constrain packaged goods, serving the circulation, storage, and transportation of goods. They are mainly used for the transportation and packaging of goods. Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material and has a specialized mold on the molding machine to shape paper products of a certain shape. It has four advantages: the raw material is waste paper, including cardboard, waste box paper, waste white edge paper, etc., Widely sourced; The manufacturing process is completed by pulping, adsorption molding, and drying and shaping, which is environmentally friendly. Can be recycled; Smaller than foam plastic, it can be stacked and transported conveniently. Pulp molding is not only used for lunch boxes and tableware, but also for industrial cushioning packaging, and has developed rapidly.

Waste paper is constantly crushed by a shredder in the pulping tank, and the egg tray raw materials in the pulping tank form egg trays on the egg tray production equipment. Different packaging products are formed on different molds, providing strong protection for fragile and perishable products. After use, it will slowly degrade in the soil and will not cause a burden on the natural environment. We need to pay attention to the details during the process of pulp molding, beating, and crushing. There is an old saying that three parts of paper making and seven parts of pulp making. During the pulping process, the pulp and fibers in the pulp are treated by the beater under the mechanical action of hydraulic crushing, causing them to become loose.

During the process of beating, crushing, and dispersing in pulp molding, paper fibers generate tensile friction, changing the shape and flexibility of the fibers. This process requires a certain amount of time rather than a single crushing concentration to determine the pulp standard. A series of details such as the speed of the pulp crusher and the installation angle of the blades.
