Is a Large Egg Carton Machine the Same as an Egg Tray Machine?

The terms egg carton machine and egg tray machine are sometimes used interchangeably in the pulp molding industry, but the final product depends on the mold design.

A large pulp molding machine can be configured for different egg packaging formats, including traditional egg trays and carton-style packaging.

The main difference is the mold structure and final product design, rather than simply the machine name.

Therefore, when requesting a quotation, buyers should provide the required egg carton or egg tray type instead of selecting a machine based only on the product name.

This allows the manufacturer to confirm the suitable mold, forming capacity, and supporting equipment.

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.

What Products Can a Large Egg Carton Machine Produce?

With different molds, a large pulp molding machine can be configured to produce different molded-pulp packaging products. The exact product range depends on the forming machine and mold design.

Possible applications include:

• Egg trays
• Egg cartons
• Fruit trays
• Apple trays
• Seedling trays
• Cup carriers
• Other molded-pulp packaging products

For egg packaging, different mold configurations can also be designed for different egg quantities and carton shapes.

If you plan to produce products other than standard egg trays, provide the product dimensions, number of cavities, and product drawings or samples. The mold and machine configuration can then be evaluated before ordering.

What Equipment Is Needed for a Complete Large Egg Carton Production Line?

A large egg carton production line normally includes four main sections: pulp preparation, egg carton forming, drying, and packaging. For a 4,000–7,000 pcs/h production line, each section should be matched with the capacity of the selected forming machine.

Production Section	Main Equipment	Function
Pulp Preparation	Hydraulic pulper, pulp refiner, agitator	Turn waste paper into uniform pulp
Pulp Supply	Pulp pump, storage tank, screening equipment	Store, filter, and supply pulp
Forming	Large egg carton machine	Vacuum-form wet egg cartons
Drying	Brick kiln dryer or multi-layer dryer	Remove moisture from wet cartons
Stacking	Automatic stacking system	Arrange finished cartons
Packaging	Packing machine	Compress and package finished products

A complete line can be configured according to the required capacity, available factory space, local energy costs, and level of automation.

For customers who already have some equipment, the production line can also be configured around the existing machinery to avoid unnecessary investment.

Process Flow

Which Drying Method Is Suitable for a Large Egg Carton Production Line?

Drying is an important part of a large egg carton production line because the forming machine continuously produces wet cartons. The drying system must have enough capacity to process the output from the forming machine.

Shuliy provides different drying options, including sun drying, brick kiln drying, and multi-layer drying.

Drying Method	Suitable Situation	Main Consideration
Sun Drying	Low investment and suitable climate	Requires large drying area and more labor
Brick Kiln Drying	Commercial production with available space	Suitable for continuous production
Multi-Layer Dryer	Large-scale and automated production	Higher investment but saves floor space

For 4,000–7,000 pcs/h production, a mechanical drying system is generally more suitable when stable year-round production and higher automation are required. The final dryer configuration should be selected according to local fuel availability, climate, factory space, and investment budget.

For reference, the 8-side production line information on this site gives multi-layer dryer dimensions of about 27.5 × 6 × 3.6 m for SL-4×8 and SL-5×8, and about 33.5 × 6 × 3.6 m for SL-6×8. Actual layouts can be adjusted according to the factory and equipment configuration.

How Much Factory Space Does a Large Egg Carton Production Line Need?

The required factory space depends on the forming machine, drying method, raw material storage, and finished-product storage. The forming machine itself occupies much less space than the complete production line, so buyers should plan the factory based on the entire process.

The factory normally needs space for:

• Waste paper and cardboard storage
• Pulp preparation
• Egg carton forming
• Drying
• Finished-product stacking
• Packaging
• Finished-product storage
• Equipment maintenance and operation

For example, a multi-layer dryer requires considerably less floor area than a long brick drying line, while sun drying requires a much larger open drying area.

Before purchasing a large egg carton machine, buyers can provide the factory length, width, and height. Shuliy can use this information to recommend an equipment layout and suitable drying solution.

How Much Does a Large Egg Carton Machine Cost?

The price of a large egg carton machine varies according to the production capacity, machine model, mold configuration, automation level, and supporting equipment.

For the 4,000–7,000 pcs/h production range, the main factors affecting the total investment include:

Cost Factor	What Affects the Cost?
Forming Machine	Model and production capacity
Molds	Product type, size, and mold material
Pulping System	Raw material and required pulp capacity
Drying System	Dryer type, capacity, and fuel
Packaging System	Manual or automatic packaging
Electrical System	Voltage and local electrical requirements
Factory Layout	Workshop size and equipment arrangement
Shipping	Destination and transportation method

The price of the forming machine should therefore not be considered separately from the rest of the production line. A buyer who needs a complete commercial production line should calculate the cost of the forming, pulping, drying, stacking, and packaging systems together.

For an accurate quotation, provide your target capacity, egg carton specification, raw material, voltage, and destination.

What Are the Costs of Using a Large Egg Carton Machine?

The production cost of egg cartons depends mainly on raw material, electricity, drying fuel, labor, water, maintenance, and packaging.

Among these costs, waste paper and drying energy can have a significant impact on the final cost per carton. Local prices should therefore be used when calculating the actual production cost for a specific project.

A basic calculation is:

Production cost per carton = Total production cost ÷ Actual number of cartons produced

The main cost items include:

Cost Item	Main Influencing Factor
Waste Paper	Local waste paper price and carton weight
Electricity	Machine power and operating hours
Drying Fuel	Fuel type, moisture content, and dryer efficiency
Labor	Production automation and local wages
Water	Pulp preparation and water recycling
Maintenance	Wear parts and operating conditions
Packaging	Packing method and packaging materials

The cost examples shown below are reference figures rather than fixed production costs. Actual costs vary by country, energy prices, raw material prices, labor rates, and operating conditions.

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

$1(USD)=¥7.2(RMB)

Large Egg Carton Machine vs. 4-Side Egg Tray Machine

The main difference between 4-side and 8-side egg tray machines is production capacity and the scale of the production line.

Feature	4-Side Machine	8-Side Large Machine
Production Scale	Small to medium	Medium to large
Typical Capacity	Lower capacity range	4,000–7,000 pcs/h
Initial Investment	Lower	Higher
Production Volume	Suitable for growing businesses	Suitable for large commercial production
Drying Requirement	Lower	Higher
Factory Planning	Relatively simple	Requires more complete line planning

A 4-side machine can be considered when the target output is lower or the initial investment needs to be controlled. An 8-side machine is designed for buyers who need higher continuous production.

The final choice should be based on target sales volume, raw material availability, factory conditions, and production budget, rather than capacity alone.
