Pre-opened Bags on a Roll Packaging Machine

JYZN-P350S-Pre-opened Roll-fed Bag Packaging Machine

he Pre-Opened Roll-Fed Bag Packaging Machine is an intelligent packaging device that integrates automatic bagging, sealing, and printing into one system. Using pre-opened continuous roll bags that open effortlessly, combined with an intelligent control system, it automatically completes the entire process of “bag feeding → bag opening → product loading → sealing → printing” with no manual intervention.

In one sentence: You load the product, it handles the rest.

Key Advantages:

✅ Pre-opened bags – no jams, no misfeeds
✅ Integrated printing – no need for separate labelers
✅ Touchscreen control – one‑tap product changeover
✅ Wrinkle‑free, smooth, and firm seals
✅ Casters for flexible mobility – single or multi‑station operation
✅ Interfaces with robotic arms, weigh feeders, MES/ERP systems

Applicable Industries: Sensors, electronic components, automotive parts, hardware tools, home appliance accessories, boxed products, and other lightweight, diversified products.

Packaging Speed: 15‑35bags/minute
