2026-06-01
Against the backdrop of global implementation of green and low-carbon policies and the continuous advancement of plastic restriction bans, fully degradable pulp molded products have become an inevitable trend to replace traditional plastic packaging. As core equipment in the pulp molding industry, Egg tray making machine uses waste paper and cardboard as raw materials. Featuring environmental friendliness, low cost and high practicality for finished products, it is an essential production device for animal husbandry packaging, food & catering, light industry, hardware and other sectors. The global market for pulp egg trays maintains steady growth with an average annual growth rate of 3%. With easily accessible raw materials, low investment threshold, short payback period and strong market demand, the Egg tray production line has made Pulp molding egg tray machine a popular investment choice in the packaging equipment industry.
1. Composition of a Complete Egg Tray Production Line
A full set of Egg tray production line consists of pulping equipment, Pulp molding egg tray machine, drying equipment and finished product packaging machine, together with auxiliary systems including negative pressure system, electric control system and conveying system to realize full automatic operation.
1.1 Pulping Equipment: Core for Raw Material Preprocessing & Stable Pulp Quality
The pulper breaks down waste cardboard, waste paper and other raw materials into fine and uniform pulp fibers through hydraulic pulping and fiber dissociation, while filtering out impurities from raw materials.
Our upgraded pulper is equipped with high-wear-resistant alloy cutter groups and circulating water pulping technology. It adopts an intelligent pulp concentration adjustment system to automatically control pulp density. Meanwhile,
the closed circulating water design minimizes water consumption and eliminates wastewater discharge, fully complying with environmental protection standards.
1.2 Pulp Molding Egg Tray Machine: Core Host Determining Product Quality and Output
Adopting vacuum negative pressure forming technology, the Pulp molding egg tray machine adsorbs well-mixed pulp onto customized molds to produce wet egg tray blanks rapidly. It is the key equipment that decides the quality, output and appearance of final products. We provide Pulp molding egg tray machine in multiple specifications, including single-sided, four-sided and eight-sided rotary structures, with an output ranging from 1,000 to 8,000 pieces per hour, catering to factories of different scales.
The machine is fitted with a PLC intelligent control system and high-precision vacuum negative pressure system. The negative pressure is stably maintained at around 0.06 MPa, and a single forming cycle takes only 12 to 25 seconds. The finished products feature uniform wall thickness and precise hole positions with a tolerance within ±0.3mm, free of burrs and deformation. Built with high-strength frames, the equipment runs stably with low vibration and failure rate, supporting 24-hour non-stop operation. Key transmission parts are made of wear and corrosion resistant materials, which greatly extend service life and reduce subsequent maintenance costs.

1.3 Drying Equipment: Intelligent Temperature Control
The dryer is used to dehydrate and cure wet egg tray blanks, so as to enhance the hardness and stability of finished products. Our fully automatic drying line adopts a multi-layer mesh belt structure and hot air circulating drying technology, different from the traditional single high-temperature drying method.
It can automatically adjust drying temperature, wind speed and conveying speed to achieve low-temperature uniform drying, effectively preventing egg trays from cracking, deforming and embrittling. The whole drying process including material conveying and discharging is fully automatic with no manual handling required.
1.4 Finished Product Packaging Equipment
The fully automatic packaging machine realizes automatic stacking, counting, bundling and sealing of egg trays, replacing the traditional manual sorting and packaging mode.

2. Production Process of the Egg Tray Production Line (From Waste Paper to Egg Trays)
With mature techniques and high automation, the Egg tray production line takes waste paper as the main raw material and features zero pollution during production. The whole process is divided into five steps:
Step 1: Raw Material Screening and Preprocessing
Sort raw materials and remove impurities such as plastic, metal and gravel.
Step 2: Hydraulic Pulping and Concentration Adjustment
Feed waste paper into the pulper. The materials are crushed and fiber-separated via circulating water to form fine and even pulp. Proper water and additives are added to adjust pulp concentration. After impurity filtration, the qualified pulp is stored in the pulp tank.
Step 3: Vacuum Forming by Pulp Molding Egg Tray Machine
Pulp is automatically delivered to the Pulp molding egg tray machine. With vacuum negative pressure adsorption technology, pulp evenly adheres to the mold surface to form wet egg tray blanks, which are then automatically demolded and conveyed.
Step 4: Automatic Drying and Curing
Wet egg tray blanks are transported to the dryer and processed by hot air circulation for gradual dehydration and curing, turning into dry, firm and well-shaped finished egg trays.
Step 5: Automatic Packaging
Qualified products are sent to the packaging machine for automatic stacking, counting, bundling and sealing.
