Product overview
What it is,
what it makes
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. 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.

How it works
How it works,
step by step
Servo-Controlled Film Loading
Raw PE tubular or thickened plastic films are mounted on the unwind shaft and advanced through the system via a precision servo motor drive. Automatic tension regulation ensures steady feed rates while accommodating film thicknesses between 0.01 and 0.30 mm.
PLC-Based Size Configuration
Operators input target measurements directly into the touch-screen PLC interface to set bag widths from 550 mm to 1150 mm and lengths up to 1500 mm. The control system synchronizes mechanical actuators to maintain exact dimensional tolerances throughout the run.
Automated Edge Fusion and Separation
Heated sealing bars press and melt the film edges to form permanent seams before a synchronized cutter divides the continuous web into individual units. This cycle repeats at adjustable production speeds ranging from 30 to 120 bags per minute.
Stable Discharge and Stacking
Completed bags are guided off the main frame and collected in a designated discharge zone for manual or automated bundling. The machine’s 2000 kg mass and 3000 x 1800 x 1200 mm footprint provide structural rigidity to minimize vibration during continuous high-speed operation.
ES-L800MM series
Three-servo non-stretch
bag making machine
A dedicated heavy-package line for LDPE, HDPE and LLDPE tubular film: flat bags, garment bags, vacuum bags, and aquatic or vegetable heavy bags — with servo-driven feeding, automatic constant-temperature sealing and SICK registration.
What it is, what it makes
The ES-L800MM is designed for non-stretch bag production from thickened tubular films. Touch-screen PLC control with servo feeding keeps cut length accurate and stable; three heating systems (hot knife, both knife ends and heated base) seal thick film cleanly without sticking or scorching.
Key features
- Touch-screen PLC with servo motor feeding — fast bag making, accurate sealing and cutting, no film stretching.
- Independent servo control for running speed: stable, low noise and energy-saving.
- Automatic constant-temperature heating that stops below set temperature — firm, smooth, sealed bag mouths.
- 10 mm / 12 mm iron-plate frame with synchronous servo-driven front and rear rubber rollers.
- Cold-press shaping knife after the ironing knife flattens the seal while it is still hot.
- Three heating systems: hot knife + both ends of the hot knife + heated base.
- German SICK color-mark tracking electric eye and automatic feeding.
