As professional automated devices built on pulp molding technology, egg tray making machines are also widely referred to as egg tray machines or pulp egg tray molding machines. Their core function is to process waste paper, virgin pulp, and other raw materials into paper trays for holding and protecting poultry eggs during transport. They can also produce fruit trays, cup holders, and industrial cushioning packaging by changing the molds. As the core machine of a pulp molding production line, it integrates multiple processes such as pulping, molding, drying, and post-processing, achieving fully automated production from raw materials to finished products. Distinguished from traditional manual production and plastic blister packaging equipment, it is a landmark piece of equipment in green packaging manufacturing.

Main Types of Egg Tray Making Machines
1. Classification by Molding Process
（1）Single-sided Egg Tray Production Equipment
Also called a flipping machine, the simplest basic model uses a single set of molds for reciprocating molding. Production capacity is 1000-1500 egg trays per hour, suitable for natural drying or small-scale drying systems.
- Advantages: Small footprint of only 15-30㎡, low investment cost, and easy operation, plus high cost-effectiveness. Besides, it can produce irregularly shaped trays with a height of up to 8 cm, including egg trays, coffee cup holders, egg boxes, and other products.
- Disadvantages: Low efficiency, requires more manual assistance, and is only suitable for small workshops or temporary production needs.
（2）Rotary Drum Egg Carton Production Line
Also known as a rotary drum machine, this is the mainstream model in the industry, available with four-sided, eight-sided, and twelve-sided rotating molds. Continuous vacuum adsorption molding ensures stable operation and a low failure rate. The capacity of a four-sided drum production line is 1500-3000 pieces/hour, an eight-sided drum production line is 3000-7000 pieces/hour, and a twelve-sided drum production line can reach 7000-10000 pieces/hour.
- Advantages: Suitable for medium to large-scale production; produces products with uniform thickness and high molding precision; can operate continuously for 24 hours.
（3）Roller Egg Carton Production Line
This ultra-high-speed model uses dual-roller synchronous extrusion molding, with a single mold production time of only 1 second and a capacity of 7000-12000 pieces/hour. Suitable for ultra-large-volume standard egg carton production.
- Advantages: High efficiency, strong product consistency, long mold life.
- Disadvantages: High equipment cost, large footprint; only suitable for large enterprises or specialized packaging plants.
2. Classification by Automation Level
- Semi-Automatic Egg Tray Making Machine: Requires manual handling of feeding, wet tray transfer, and stacking. Capacity is 1000-3000 trays/hour. Simple configuration and low price. Suitable for start-up workshops and small regional farms.
- Fully Automatic Egg Tray Making Machine: PLC-controlled intelligent process, from pulping, molding, drying, to stacking and packaging, with no human intervention. Capacity is 3000-12000 trays/hour, reducing labor costs by 70%. Divided into small and medium-sized (3000-6000 pieces/hour) and large-scale (over 6000 pieces/hour), suitable for medium and large-scale egg processing plants and large-scale packaging enterprises.
Egg Tray Making Machine System Composition
- Pulping System: Includes a pulper, refiner, and pulp tank. It breaks down waste paper into uniform pulp, removes impurities, and adds waterproofing and strengthening agents, controlling pulp concentration and quality.
- Forming System: The core unit of the equipment, including forming molds, a vacuum system, and transfer molds. It uses vacuum adsorption to form the pulp into wet egg trays, controlling product thickness and shape.
- Drying System: A multi-layer mesh belt drying line or drying chamber, using clean energy such as natural gas or electricity. It features segmented temperature control and hot air circulation to quickly remove moisture from the egg trays, preventing deformation and cracking.
- Post-processing System: Includes demolding, edge trimming, calendering, and stacking equipment. It removes burrs, improves flatness, and automatically counts and stacks the trays. Some models can be integrated with egg sorting systems for unified production.
- Control System: A PLC intelligent control panel with timing accuracy of ±0.5 seconds. It features one-button start/stop, production counting, fault alarms, and parameter adjustment functions, achieving precise control throughout the entire process.
