egg carton manufacturing process
The complete egg cartons involves several key stages: pulping process, molding process, drying process, and packaging process.
Pulping Process
Recycled paper (such as discarded cardboard boxes, waste newspapers, and corrugated paper) is the main raw material. The process begins by feeding this paper into a hydrapulper, where it is broken down into pulp. This helps separate the fibers while also removing some impurities. After this initial step, the pulp is refined through screening and defibering to make it smoother and more uniform. Once the pulp reaches the required consistency, it is ready for the next stage-molding.
AGICO supply Mini Pulping Machine,Standard Pulping Machine,Medium Pulping Machine,Large Pulping Machine.
Molding Process
Once the pulp is ready, it is precisely pressed into the shape of egg cartons using specialized molds. The entire molding process is fully automated, ensuring that each carton is uniform in shape and size while maintaining high production efficiency.
AGICO provides customized solutions. By simply changing the mold, the same machine can produce a variety of molded pulp products, including shoe trays, apple trays, seeding trays, wine bottle holders, and inner packaging for electronic items.
Drying Process
After molding, the freshly formed egg cartons are transferred to a drying line. Here, hot air circulates around them to remove moisture and complete the drying and setting process.
AGICO offers four main types of drying lines for egg cartons.
Single-layer Metal Dryer：It is ideal for applications with ample space requiring rapid drying but with a large footprint.
Multilayer Metal Dryer：It saves space and reduces overall costs.
Civil Engineering Drying Equipment：While it occupies a larger area, its cost is lower than metal drying.
Box Type Dryer：It features an integrated design, compact structure, and high space utilization.
Packaging Process
Once dried, the finished egg cartons are counted, stacked, and packaged to prepare them for storage and transport.

Raw materials for making egg cartons
AGICO adopts a diversified approach to raw materials in its egg tray production, consistently using sustainable sources. This includes a comprehensive range of materials such as recycled waste paper (like waste newspapers, waste magazines, and waste cartons), industrial paper waste, and eco-friendly alternatives like bamboo pulp and straw pulp. These materials are finely crushed and processed through a specialized pulping system, ultimately being transformed into egg trays and other packaging products known for their strength and stability.
Different raw materials are matched to various application needs.
For instance, virgin or recycled paper pulp boards offer excellent fiber strength, making them suitable for high-end products with strict quality requirements.
Straw and other agricultural residues provide a cost-effective, lightweight, and reliable solution.
Bamboo pulp, prized for its superior toughness and natural biodegradability, is a key choice in our eco-conscious production.
This diverse material system allows us to flexibly manufacture a wide range of tray products, from standard to heavy-duty types.
Beyond performance, AGICO also emphasizes the synergy between cost and environmental responsibility. Compared to using virgin pulp, our production methods offer a cost advantage of 30%–50%. Furthermore, by efficiently reusing industrial and post-consumer waste, we actively contribute to a circular economy.
Our entire process effectively integrates various fiber resources, transforming them into packaging products that balance functionality, economic efficiency, and environmental responsibility to meet the diverse needs of the market.

Application of Egg Carton Machinery
Thanks to its excellent adaptability, the AGICO egg tray machine demonstrates broad application value across industries, including poultry farming, animal husbandry, agriculture, food service, industrial manufacturing, and even the medical sector.
Its standout feature is the flexible mold changing system, which allows for a quick mold change in just three minutes, enabling "one machine for multiple uses." This means you can not only produce egg trays but also switch molds to process fruit trays or seedling trays.
As orders change, you can readily shift to producing coffee cup holders, disposable tableware, or medical trays. This rapid switching capability allows a single piece of equipment to easily meet the diverse needs of different industries, saving on equipment investment costs while enhancing production flexibility.
FAQ about AGICO egg carton machinery
Yes. By simply changing the mold, the same machine can produce egg trays, fruit trays, seedling trays, shoe trays, wine trays, and electronic product liners, etc.
Yes. Colorants can be added directly during the pulping stage to produce uniformly colored egg trays.
Usually, orders are shipped within 30 days of confirmation, depending on the model and configuration.
A standard fully automated production line (including pulping to packaging) requires approximately 300 to 500 square meters of space.
The equipment features an energy-saving design and a water recycling system, designed to help you effectively control operating costs.
