850ABA Blowing and Printing (Vest Bag) Live Demonstration

2025-06-11

850 ABA film blowing and printing (vest bag) film blowing machine unit is a high-efficiency plastic processing equipment integrating film blowing and printing functions, specially used for the production of vest bags (vest bags, handbags, etc.)


Model analysis:

"850" means the maximum folding width of the film tube is 850mm (adjustable), and "ABA" means a three-layer co-extrusion structure (A/B/A layer, the middle layer can be recycled material or functional layer, and the inner and outer layers are high-quality raw materials).

Continuous blowing and printing:

Integrate the film blowing molding and printing processes to achieve continuous production from raw materials to printed bags, reduce intermediate links, and improve efficiency.



Expert Insights & FAQ

Define output based on your specific film gauge and resin type. Real-world performance depends on maintaining bubble stability at your thinnest target micron. What are the Industry 4.0 requirements for new machines?

Yes, but it requires specific specs. For a 15-150 micron range, you need an adjustable die gap, an 8:1 haul-off speed range, and a flexible air ring. Changeover time usually takes 30-45 minutes. How Adjusting die gap

The extruder screw diameter determines the output capacity (kg/hr), while the die head diameter and Blow-Up Ratio (BUR) determine the film's layflat width. To spec a machine, you should define your target width and thickness first, then work backward to determine the required output and screw size. How do I spec the right extruder size for my target film width?
