Air column bag making machine: detailed explanation of product functions
The air column bag making machine production line is a highly integrated automation system, whose main function is to convert plastic film raw materials into inflatable cushioning packaging products. Its core modules include:
1. Film making and printing unit (optional)
* PE/PA or degradable PLA particles are melted into film through an extruder, and the thickness accuracy can reach ±0.01mm
* Supports customized printing of corporate logos, warning slogans, etc. (applicable to brand packaging scenarios)
2. Heat sealing and molding unit
* Independent air column cavity is formed through high-frequency hot pressing technology, and the sealing strength is ≥3.5N/15mm
* Single-layer/double-layer air column structure can be produced to adapt to different bearing Weight requirement (5kg-100kg)
3. Inflating and testing unit
*Use vortex vacuum pump to achieve high-speed inflation (0.5 seconds/strip), air pressure error ≤0.01MPa
*Equipped with infrared leak detector, automatically remove damaged air column (defective rate <0.3%)
4. Slitting and winding unit
*Ultrasonic slitting technology avoids burrs and supports customized coil length (50m-500m/roll)
*Tension control system ensures winding flatness error <1mm
Working principle: Full process analysis from raw materials to finished products
Process diagram:
Plastic granules → Melt extrusion film forming → Air column cavity heat sealing molding → Air filling → Seal detection → Slitting and winding/packing
Key technical nodes:
1. Multi-stage temperature control system
* The extruder is divided into 5 temperature zones for precise temperature control (160℃-220℃) to ensure the balance between film ductility and tear resistance
2. Closed-loop air circuit management
* Real-time feedback adjustment of inflation pressure to avoid deformation of air column due to unstable air pressure
3. Intelligent linkage logic
* PLC control system coordinates the speed of each unit, for example: the inflation rate automatically matches the film conveying speed

Air column bag making machine:Core value for manufacturers
1. Production efficiency revolution
*Compared with manual filling: a single production line can replace 50 workers, and the production speed is increased by 20 times
*Case: After a daily chemical enterprise introduced the equipment, the labor cost of the packaging link was reduced by 72%
2. Material cost optimization
*The volume of the air column bag is only 1/30 of that of the traditional foam, and the storage space is saved by 65%
*The scrap recycling system can increase the reuse rate of waste film to 95%
3. Environmental compliance advantages
*Compliant with EU certification
*When using biodegradable film, the natural degradation rate in 180 days is ≥90%
4. Order acceptance capacity upgrade
*Supports a minimum order quantity of 1 machine, helping to contact high-profit orders
*Reduce inventory backlogs through JIT (Just-in-Time) mode
