Polystyrene Foam Lunch Box Making Machine

Product Description

The Polystyrene Foam Lunch Box Making Machine is a highly efficient and versatile equipment designed for the production of disposable polystyrene (PS) foam lunch boxes, trays, and other food containers. This machine utilizes thermoforming technology, which involves heating PS sheets to their softening point and then forming them into the desired shape using molds.

The production process starts with feeding pre-cut PS sheets into the machine's heating chamber, where they are heated uniformly by infrared heaters. Once the sheets reach the optimal forming temperature, they are transferred to the forming station, where a combination of vacuum and pressure forces them to conform to the mold cavities. After cooling and solidification, the formed lunch boxes are trimmed to remove excess material, and then ejected from the machine.

The machine can be equipped with single or multi-cavity molds, allowing for the production of different sizes and designs of lunch boxes, from small snack containers to large multi-compartment meal boxes.

Features

High Precision Molding: The advanced mold design and precise temperature control ensure uniform wall thickness and clear surface details, resulting in lunch boxes with excellent structural strength and aesthetic appeal.

Automatic Operation: The machine is fully automated, from sheet feeding to product ejection, reducing labor costs and improving production efficiency. It can achieve a cycle time as low as 5 seconds per mold cycle.

Multi-Product Capability: By changing the molds and adjusting the process parameters, the machine can produce a wide range of PS foam products, including trays, bowls, and clamshell containers.

Energy Saving: The intelligent heating system adjusts the temperature based on the production speed and material type, reducing energy consumption by up to 30% compared to traditional thermoforming machines.

Safety Features: Equipped with emergency stop buttons, safety guards, and overload protection systems, the machine ensures safe operation for operators.

Application

Food Service Industry: PS foam lunch boxes are widely used in fast-food restaurants, cafes, and food trucks for packaging takeaway meals, snacks, and desserts. They provide excellent insulation, keeping food hot or cold for longer periods.

Catering and Events: Large-capacity lunch boxes are ideal for catering services, buffets, and outdoor events, where convenient and hygienic food packaging is essential.

Food Processing and Retail: They are also used in food processing plants for packaging pre-prepared meals, sandwiches, and fresh produce, ensuring product safety.

Medical and Pharmaceutical: In some applications, PS foam containers are used for packaging medical supplies and pharmaceuticals that require temperature-controlled storage.

Faq

Q: Are the produced lunch boxes safe for food contact?

A: Yes, the machine uses food-grade polystyrene resin that complies with international safety standards, such as FDA (USA) and EU 10/2011, ensuring no harmful substances migrate into the food.

Q: Can the machine handle recycled PS materials?

A: Yes, it can process recycled PS sheets as long as they are clean, free of contaminants, and meet the required mechanical properties for thermoforming.

Q: How many different mold designs can the machine accommodate?

A: The machine is compatible with any standard thermoforming mold, and mold changes can be done within 60 minutes, allowing for quick product switching.

Q: What is the maximum size of lunch box the machine can produce?

A: The standard model can produce boxes up to 300mm in length, 200mm in width, and 100mm in depth, while custom models can be designed for larger sizes.
