Biodegradable Molded Pulp Trays Wet Press Cosmetic Packaging Inner Box

The production process of the paper pulp tray starts with the collection of waste paper, including corrugated packaging and newsprint. By adding water and exposing it to the reduction process, the paper becomes pulp. During this process, stabilizers and binders such as soluble wax and aluminum sulfate are added. Once the pulp is ready, the mold of the desired product is immersed in it.

The mold is porous and connected to a powerful vacuum source and waste water mesh system. Once immersed, the vacuum is activated, which draws water away from the entire surface of the mold. This effect makes the paper fibers suspended in the pulp stick to the outside of the mold when water passes through.
