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: Adopts touch screen PLC computer control and 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 and fixed quantity, automatic alarm, shutdown or restart, ensuring stable and efficient production.
• Stable & Energy-saving Servo Drive: The main engine adopts a servo control system, which has the advantages of stable operation, low noise and energy saving compared with frequency conversion speed regulation. The whole machine’s running speed is controlled by independent servo motors, which can not only increase production speed but also ensure transparent and firm heat sealing when making hem bags, avoiding bag scalding under high temperature.
• Automatic Constant Temperature Heating: Equipped with an automatic constant temperature heating system, which will automatically stop when the temperature difference is lower than the set value. This effectively reduces the defective rate caused by temperature fluctuations, making the bag mouth seal firm, smooth and beautiful. The machine is equipped with three sets of heating systems (hot knife + both ends of the hot knife + base) for comprehensive and stable heating.
• Stable Unwinding Mechanism: Adopts analog unwinding system with frequency conversion speed regulation, which can realize one-button synchronization with the main machine, ensuring stable feeding and avoiding material deviation or stretching during the unwinding process.
• Sturdy Structure & Reliable Sealing: The machine adopts 10mm/12mm iron plate structural frame, with high stability. The front and rear rubber rollers are driven synchronously by servo drive; the ironing knife uses knob heavy pressure to adjust the pressure value, and the base is heated and closed up and down to prevent the film from sticking to the knife. Ironing and cutting knives are equipped with air blowing cooling and feeding devices, and a cold-pressed shaping knife is installed in front of the ironing knife to flatten the ironing line when it is still hot, achieving cooling and shaping effects. The final ironing line is beautiful, smooth and attractive, with high customer acceptance.
• Automatic Feeding Function: The feeding part is equipped with an automatic feeding function, which saves the trouble of manual feeding when there is no material, reducing labor intensity and improving production continuity.
• High-precision Tracking: Adopts imported color code tracking electric eye (German SICK brand), ensuring accurate tracking of printed films and consistent product specifications.
