How to Make Egg Cartons?
Large egg carton machines use waste paper, cardboard, old books and newspapers, paper mill pulp, bamboo pulp, or wood pulp as raw materials. The pulp is processed into a uniform slurry. The slurry is vacuum-formed on molds to quickly shape wet egg carton blanks. The wet blanks are then automatically demolded and sent to a drying line or air-drying area, producing strong, uniform egg cartons. The machine runs continuously and stably, suitable for 24-hour uninterrupted production.
Applications
- Packaging for eggs, duck eggs, and other poultry eggs
- Supporting egg processing factories and farms
- Pulp molding product factories
- Export-oriented eco-friendly packaging production lines
What Are the Costs of Using a Large Egg Carton Machine?
Besides the equipment purchase, daily production of egg cartons also involves the following expenses:
| Cost Item | Description | Unit Cost per Tray (RMB) |
| Raw Material | 1 ton of waste paper can produce 12,000–15,000 trays (based on tray weight). Based on 80g per tray: 1,000,000g ÷ 80g = 12,500 trays Waste paper price: ¥1500/ton → 1500 ÷ 12,500 = ¥0.12 per tray | ¥0.12 |
| Labor | Sun drying: 6 workers; drying by machine: 4 workers. In China, Labor is often calculated by piecework: approx. ¥0.02 per tray. | ¥0.02 |
| Electricity | Varies with capacity and power consumption. Higher output means lower cost per tray. | ¥0.02 |
| Drying Fuel | Coal (5000 kcal/kg) Wood (4000 kcal/kg) Natural Gas (8900 kcal/m³) Diesel (11,900 kcal/liter) | ¥0.03/pc ¥0.03/pc ¥0.06/pc ¥0.08/pc |
| Pigment (optional) | ¥12/kg pigment; 1 kg can produce approx. 3000–4000 trays | Approx. ¥0.003–0.004 |

What Is the Process of Producing Egg Cartons?
Process Flow
Raw Material Preparation
Select eco-friendly materials such as waste paper and cardboard. Remove impurities to ensure stable pulp processing at 320–480 kg/h (SL-4×8–SL-6×8).
Pulping
Soak and beat the materials into uniform pulp. This ensures smooth molding and provides stable slurry for producing 4,000–7,000 egg cartons per hour.
Forming
The 8-face rotary molding structure sucks, dewaters, and demolds the pulp. It ensures consistent wall thickness and uniform size, allowing high-efficiency continuous production.
Drying
Remove moisture using brick kilns or multi-layer dryers. Egg cartons become strong and stackable, processing 640–960 kg of water per hour.
Inspection and Packaging
Check dimensions and mold quality, then neatly stack and package the cartons to ensure safe transport and efficient delivery.
Can Egg Carton Molds Be Customized?
Yes, Shuliy supports custom egg cartons, including printing your company logo or creating unique shapes. We first provide design drawings for approval, then produce the molds.
- Size and Specifications: Molds can be customized for egg carton capacity (e.g., 6, 10, 12 eggs), egg spacing, tray thickness, and more.
- Special Shapes: Molds for irregular egg cartons or specific eggs such as duck or goose eggs can be made.
- Material Options: Aluminum alloy, plastic, or stainless steel molds can be chosen based on production volume, durability, and demolding needs.
Can One Egg Carton Machine Use Different Molds?
- Standard Design: SL series large egg carton machines use a modular mold structure for quick installation and removal.
- Multiple Sizes: By changing molds, the machine can produce different carton sizes, such as 6, 10, 12 eggs, or custom dimensions.
- Material Options: Molds are usually aluminum alloy, plastic, or stainless steel, chosen based on production volume, durability, and demolding needs.
Notes for Custom Molds
- Provide egg carton dimensions, tray quantity, and thickness requirements in advance.
- Different mold materials vary in wear resistance and lifespan; select according to production volume and drying method.
- Custom molds require a production period but offer long-term use and stable returns.
