What Machines Are Needed To Make Bags?

The machines needed to make bags vary according to the type of bag (such as non-woven, plastic, paper bags, etc.) and the complexity of the process. Here's a look at the core devices and functions of common bag-dusters:
I. Non-Woven Bag Making Equipment
Fully automatic non-woven cloth bag maker
Function: production of non-woven cloth drawstring bags, handbag, flat bag, etc., support ultrasonic welding technology (alternative to traditional sewing), waterproof sealing edge.
Core Configuration:
Robotic arm, non-woven cloth conveyor, cutting machine, sealing machine, pneumatic press;
Equipped with stepper-type length setting and automatic counting devices;
Intelligent touch screen control, automatic deviation correction, double-roll feed and other functions (such as (e.g., Zhejiang Zhengxin Machinery E700 five-in-one bag machine).
Efficiency: Mainstream models,such as the E700, can produce five bags, including flat and drawstring bags, with speeds of up to 230 bags per minute.
Ultrasonic Non-Woven Packaging Machine
Applicable Scenarios: Packaging of particulate/powdered articles in the food, pharmaceutical and chemical industries.
Features:
Highly automated: bagging, metering, filling, sealing, cutting, counting in one line;
Advanced control method: Touch screen operation + PLC control, driving stepper motors to precisely control length of the cloth bag;
Sealing advantage: Ultrasonic high-frequency vibration seal performance is excellent, sealing strength is high.
ii. Plastic bag manufacturing equipment
Soft Packaging Bagging Machine
Usage: to plastic, dust-free cloth, non-woven fabric as raw materials to produce packaging bags, applied in food, medical, electronics and other industries.
Process flow:
The feeder transports powder/liquid to the hopper;
Photoelectric positioning controls the guide speed and guides the sealing paper/other material to the front of the seal with the guide roller;
The longitudinal sealer connects the material into a cylindrical shape, automatic metering it, and then material filling.
Horizontal seal the heat seal and cut, then pull down to form a flat, three-sided seal.
High-Speed Automatic Three-sided Bagging Machine
Applicable Materials: plastic composite film, aluminum foil composite film, paper bag composite film, etc.
Core Configuration:
Three-servo control system with high precision and high speed positioning;
Computer automatic control, parameter CRT display, can be preset bag, temperature, etc.
It has the function of automatic fault alarm and automatic measuring of cloth bag length.
III. Paper bag manufacturing equipment
Paper bag machine
Features: Production of eco-friendly paper packaging bags, such as shopping bags, garment bags, food bags, etc.
Core Configuration:
Variable frequency speed regulation, servo system, PLC control technology;
Automatic gluing, molding, bottom folding, counting function;
Modular mechanism and photoelectric deviation correction system support fast model changeover (within 30 minutes).
Efficiency:
Bag line speed is 80 m / min and bag width is regulated by 300-600mm.
Production capacity is 2,500 to4,500 paper bags per day (e.g., Ouno's third-generation Supreme No-Waistline Paper Bag Machine).
Fully automated food paper bag machine
Process flow: rolled paper edge folding, molding, cutting, gluing, bottom folding, bottom pasting, finished bag output all at once.
Applicable Bag Types: Shopping bags, garment bags, snack food bags, bread bags, etc.
IV. INTRODUCTION Other Specialized Equipment
Packaging Bags
Functions: producing flour bags, knitting bag, express bag, etc.
Type:
Woven Bag Cutting, Sewing, printing integration equipment: automatic cutting, sewing, printing production line;
High-speed automatic double-sided express bagging machine: automatic rubber breaker, production of electroniccommerce packing bags.
ClothBag Automatic Packing Machine
Function: To pick, open, insert and seal the bag by using a robotic arm to complete filling and coding operation.
Applicable Scenarios: Large automated packaging of small-规格 (small-sized) products such as food and condiments.
