How to Make Paper Egg Trays? The 8-Sided Egg Tray Making Machine Shows You Step by Step
Paper egg trays, made from recycled waste paper, are ideal for packaging eggs, fruits, and vegetables thanks to their cushioning and breathability. As e-commerce and fresh produce markets grow, demand for paper trays keeps rising. To meet this demand, the 8-तरफा अंडे की ट्रे बनाने की मशीन has become the go-to choice for manufacturers upgrading their production lines.
Compared to traditional 1- or 4-sided machines, it offers more forming stations, higher output, and shorter downtime. The 8-sided design also allows for quick mold changes and customization for different products, helping businesses reduce costs and stay competitive.
So, how exactly does the 8-sided machine make paper egg trays? Let’s take a closer look.
Raw Materials and Collection for Paper Egg Trays
The main raw material for paper egg trays is waste paper—such as old newspapers, cartons, and cardboard. These materials are recycled and reused, making egg trays an eco-friendly packaging solution.
Types of Raw Materials
- Old Newspapers
Long fibers provide good toughness and flexibility. Egg trays made from newspaper pulp are strong and resistant to cracking—ideal for protecting fragile items like eggs.
- Cartons & Cardboard
Shorter fibers, but low-cost and suitable for mass production. After pulping, they offer good structural strength, perfect for thicker or reinforced trays.
- Mixed Waste Paper
A blend of various paper types with flexible ratios, customized to meet different strength and thickness needs.
- Special Paper Waste (Optional Additions)
Materials like kraft paper or white cardboard may be added to improve surface smoothness or pressure resistance—based on customer requirements.
How Waste Paper Is Collected
- Recycling Companies
Major suppliers of waste paper include collecting large quantities, such as old newspapers (ONP), old magazines (OMG), mixed office waste (MOW), and packaging materials like boxes and containers.
- Individual Sources
Paper waste from households or offices, typically smaller in volume and is sold to recycling stations. These materials are more varied and often lower-grade.
- Paper Factories
Scraps and off-cuts from paper mills, packaging plants, and printing houses. This type of waste paper is usually cleaner and more consistent—ideal for reuse in production.
Production Process of the 8-Sided Egg Tray Forming Machine
The 8-sided egg tray forming machine is a fully automated pulp molding system, widely used to produce eco-friendly trays for eggs, fruits, vegetables, and industrial packaging. Its production process consists of four main systems.
पल्पिंग प्रणाली
- Raw Material Feeding: Waste paper, old newspapers, and cartons are fed into the hydraulic pulper.
- Pulp Preparation: The materials are shredded into pulp fibers under water agitation. Pulp consistency varies by product.
- Pulp Mixing & Adjustment: The pulp is diluted, filtered, and homogenized in mixing tanks to meet forming requirements.
Forming System
- Vacuum Forming: The pulp is pumped to forming molds, which are submerged in the pulp tank. Under vacuum suction, fibers form a wet tray on the mold surface.
- 8-Sided Rotary Table: Equipped with 8 sets of molds, the rotary platform ensures continuous forming, dewatering, and demolding.
- Automatic Demolding: Compressed air blows the wet tray off the mold for the next process.
Drying System
- Drying Options: Choose from metal drying lines, brick drying tunnels, or natural sun drying based on factory setup.tacking & Packing System
- Automatic Stacking: Dried trays are neatly stacked by the automatic stacker, improving packing efficiency.
- Packing & Delivery: Trays are packed manually or automatically, then boxed for shipment—completing the production line.
Key Advantages of the 8-Sided Egg Tray Machine
