Production Features of Plastic Lunch Box Making Machine

March 25, 2025




In the food packaging industry, the demand for plastic lunch boxes continues to grow, and the performance of production equipment directly affects product quality and production efficiency. The plastic lunch box thermoforming machine developed by our company adopts advanced technology, integrating machine, gas and electricity, which has the advantages of high efficiency, precision and energy saving, and can meet the production requirements of different customers.


Intelligent Control system



The Plastic Lunch Box Making Machine adopts Taiwan Delta PLC + color touch screen control system, with friendly man-machine interface, intuitive parameter setting and more convenient operation. 


The Plastic Food Container Making Machine has the function of memorizing product information and parameter files, which can store multiple sets of production data, and can be called up by one key when changing molds and materials, which greatly reduces the debugging time and improves the production efficiency.


Efficient Molding Technology



Positive and negative pressure synergistic molding: Adopting the upper and lower mold molding method, combining positive pressure blow molding and negative pressure adsorption technology, making the sheet uniformly stretched to ensure the product contour is clear and the thickness is consistent, applicable to complex structure products.


Servo motor precise feeding: the feeding system is driven by servo motor, the feeding length can be adjusted steplessly, high speed and precise, avoiding the error of traditional mechanical feeding and improving the material utilization rate.


Intelligent Temperature Control System



Upper and lower heating, four/five independent temperature control (large layout requires five heating), to ensure that the sheet is heated uniformly, avoiding localized overheating or insufficient cooling.


Fully computerized intelligent temperature control system, adopting zone one control one technology, with high fine-tuning precision, extremely fast heating (0-400℃ only takes 3 minutes), temperature fluctuation ≤±1℃, not affected by external voltage, with excellent stability.


Energy saving 15%, at the same time to extend the service life of the electric furnace, reduce production costs.


Automatic Production



Servo-driven molding and cutting: mold opening, mold closing and cutting actions are controlled by servo motors, which provides smooth operation and precise positioning, reduces mechanical shock and extends equipment life.


Automatic counting and stacking: automatic counting and downward stacking are adopted to facilitate collection and packaging and reduce manual intervention.


Automatic width adjustment and loading: The width of the chain track for feeding sheets can be synchronized and adjusted automatically or electrically, adapting to different widths of sheets. Mechanical loading roll device with automatic feeding reduces labor intensity of workers and improves production continuity. Automatic removal of electric furnace: When maintaining or replacing the mold, the electric furnace can be removed automatically, which is convenient for operation and improves safety.


Energy Saving and Environmental Protection



This Plastic Lunch Box Making Machine is designed with energy saving and environmental protection in mind:


Intelligent temperature control system reduces heat loss and saves more than 15% energy compared with traditional models.


Servo motor drive, lower energy consumption and less noise than traditional hydraulic or pneumatic system.


High-efficiency molding process, reducing waste generation and improving material utilization.


Flexible Adaptation



The plastic lunch box thermoforming machine is suitable for PP, PS, PET, PLA and other plastic sheets.


Applied in many fields such as food service distribution, food packaging, supermarket fresh food, etc.


Customer return on investment analysis shows that although high-end models have a large initial investment, high efficiency, compatibility, low scrap rate and energy saving usually recoup the difference within 1-2 years. Capable of adapting to future trends in materials and products.


Our plastic lunch box thermoforming machine can provide stable and efficient solutions to help customers improve competitiveness and seize the market opportunity. For more technology or customized solutions, please feel free to contact us!
