What is a Pulp Tray?

Pulp tray is an effective packaging element produced from pulp. Molded pulp products are made by reducing waste paper to pulp. The process includes the addition of various performance enhancers.


1. What is the pulp tray made of?


The porous mold is immersed in the pulp, and the water is drawn from the pulp by a strong vacuum. This creates fibers in the pulp, which adhere to the outside of the mold and form. The molded paper part is then removed from the mold, dried, and the pulp tray is made of recycled paper (such as newsprint).


2. Pulp trays are widely used


The ubiquitous pulp tray is one of the most commonly used packaging materials, and its application range is very wide, such as shock-absorbing inserts in high-end electronic product packaging, and beverage trays in fast food restaurants. Products can be used to absorb or contain liquids, and can be made into various shapes, colors and textures.


Pulp trays are also an excellent example of green products. Most pulp trays are made from recycled waste paper, a process designed to optimize the water used in the production process. The process of manufacturing molded pulp products is also quite simple, and the cost is significantly higher compared to other packaging solutions.


3. The production process of pulp tray


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.


The water passing through the mold is collected and recycled back to the pulp reduction process for reuse. When the adhered fiber layer reaches the desired thickness, the mold is taken out of the pulp. The pulp tray that accurately reflects the mold surface can now be taken out using a transfer mold and placed in an electrical component or thermal fluid drying device, where it is slowly dried for distribution.
