USE:

Our Non-stretch Heavy-duty Bag Making Machine is a professional and high-performance production equipment specially developed for heavy-duty packaging scenarios. It is specifically designed for producing flat bags, garment bags, and vacuum bags made of LDPE, HDPE, LLDPE and other tubular plastic films and thickened plastic films. As an ideal device for manufacturing a variety of heavy-duty packaging bags such as seafood bags and vegetable bags, this machine features multi-functional integration, realizing one machine for multiple uses and perfectly meeting the heavy-duty packaging needs of the aquatic product, agricultural, and textile industries.

Core Performance & Features

Advanced Intelligent Control: This bag making machine adopts a touch-screen PLC computer control system and a domestic servo motor feeding system. It boasts fast bag-making speed, high sealing and cutting precision, and excellent non-stretch performance. Equipped with functions like photoelectric tracking, automatic counting, arbitrary setting of fixed length/quantity, and automatic alarm/shutdown/restart, it ensures stable and efficient production.

Stable & Energy-saving Servo Drive: The main drive utilizes a servo control system, offering advantages in stable operation, low noise, and energy savings compared to traditional frequency conversion speed regulation. The entire bag making machine‘s running speed is controlled by independent servo motors, which not only increases production speed but also ensures transparent and firm heat seals for hem bags, preventing bag damage from excessive heat.

Automatic Constant Temperature Heating: Equipped with an automatic constant temperature heating system that deactivates when the temperature is below the set value. This effectively reduces the defect rate caused by temperature fluctuations, resulting in firm, smooth, and aesthetically pleasing bag mouth seals. The machine features three heating systems (hot knife + both ends of the hot knife + base) for comprehensive and stable heating.

Stable Unwinding Mechanism: Incorporates an analog unwinding system with frequency conversion speed regulation, enabling one-touch synchronization with the host machine. This guarantees stable material feeding and prevents deviation or stretching during the unwinding process.

Sturdy Structure & Reliable Sealing: This heavy-duty bag making machine is built with a 10mm/12mm thick steel plate frame for high stability. The front and rear rubber rollers are synchronously driven by servo motors. The sealing knife pressure is adjusted via a knob, and the heated base closes upward to prevent film sticking. The sealing and cutting knives feature air-cooling and feeding devices. A cold-press shaping knife installed in front of the sealing knife flattens the hot seal line for cooling and shaping. The final seal line is beautiful, smooth, and visually appealing, ensuring high customer acceptance.

Automatic Feeding Function: The feeding section includes an automatic feeding function, eliminating the need for manual intervention during material run-out, reducing labor intensity, and improving production continuity.

High-precision Tracking: Utilizes an imported color mark tracking sensor (German SICK brand), ensuring accurate tracking of printed films and consistent product dimensions.
