We all know that egg tray is an environmentally friendly packaging material, so do you know that the most basic step in making egg trays is pulping? Let’s take a look at the raw materials for pulping, pulping equipment, pulping process and application of paper pulp.

Raw material for making pulp

The main raw materials for making pulp include waste paper, waste cardboard, paper and other recyclable materials. These raw materials can be purchased or collected at waste recycling stations or waste paper recycling points for reuse of resources.

Pulping equipment

Making pulp usually requires the use of a paper pulper. This equipment is capable of pulverizing raw materials such as waste paper into fine fibers, laying the foundation for the subsequent production of egg trays.

There are different types and sizes of pulpers, so you can choose the right model according to your production needs.

Process to make pulp for egg tray

  1. Soaking: The collected waste paper and other raw materials are soaked in water to soften the paper for subsequent processing.
  2. Pulping: The soaked raw material is fed into the pulper for pulping. The pulper will crush the raw materials into fine fibers to form pulp for egg tray making.
  3. Adjustment of consistency: According to the actual needs, the consistency of pulp can be adjusted by adding water or dehydration to meet the requirements of different products.

In the process of making pulp, pay attention to controlling the quality of pulp to ensure its uniform and stable texture. Regular maintenance of the pulper is carried out to ensure the normal operation of the equipment.

At the same time, the selection and treatment of raw materials should be careful to avoid adulteration of harmful substances.

Application of paper pulp

The made pulp can be used to produce a variety of paper products, such as egg trays, egg cartons, fruit trays and so on. It has a wide range of applications and can meet the packaging needs of different industries, with high economic value and environmental friendliness.
