Foaming, adding a proper amount of foaming agent or high pressure gas simultaneously during the melting process, thereby generating a plurality of bubbles in the plastic material, and causing voids in the bubbles of the plastic material absorbing layer. Wherein, the blowing agent may be a physical blowing agent such as a low boiling organic compound such as butane, pentane, petroleum ether or difluoromethylene chloride, or a chemical blowing agent such as azobisformamide ( Azodicarbonamide), an organic azo compound such as azobisisobutyro nitrile (AIBN), and the high pressure gas may be carbon dioxide, nitrogen, gas, air, diethyl ether or a gaseous inert gas. In addition, The method can adjust the residence time of the plastic material in the injection molding machine, adjust the foaming temperature of the plastic material (for example, increase the foaming temperature, reduce the melting strength of the bubble, and generate voids) or adjust the pressure value of the injection molding machine. And causing the air bubbles of the plastic material absorbing layer to generate a gap; in this process, in addition, the bubble of the plastic material absorbing layer close to the surface is melted to form a surface layer due to a certain high temperature and pressure output process, and the surface layer is caused by bubbles. Melting is in a state of forming a surface seal, and the rate of adsorption of the bubbles in the absorbing layer is about six times or more, that is, the liquid capacity of the bubble which can be adsorbed in one unit space can be obtained by control, and thus the design The appropriate volume of the container can be calculated according to the amount of liquid adsorbed by the bubble to meet the appropriate liquid adsorption requirement, and the excessive liquid adsorption amount is prevented, so that the contents of the fresh food material are quickly dried up due to excessive adsorption of water on the surface.

Puncture holes pierce a plurality of holes in the surface of the foamed plastic material. The main layer is formed by a roller having a needle on the surface, and the surface layer of the foamed plastic material is rolled to form a plurality of holes, and the penetration depth of the holes is from the surface layer to the bubble. Up to the absorption layer, wherein the spacing of the holes formed in the surface layer can be adjusted according to the size of the surface area of the container.
