Equipment summary

Selection summary

Model 500 uses an external vacuum nozzle and 450 mm sealing assembly, with adjustable evacuation, gas-flush, sealing and cooling times for larger bags.

Product Description

The Model 500 processes the bag mouth without placing the whole package inside a chamber. Its external nozzle evacuates the pouch, and the controller can set gas flushing, heat sealing and cooling. The front table supports larger packs.

Vacuum performance depends on pouch barrier properties, bag-mouth flatness and product permeability. Provide bag size, fill weight and target vacuum for sample testing. Machine and sample images are from page 3 of the 2026 Yigao catalog.

FAQ

How does an external-nozzle machine differ from a chamber machine?

It handles only the bag mouth and is not limited by chamber volume, but pouch barrier performance directly affects vacuum retention.

What data is needed for selection?

Provide bag width and length, material, fill weight, product form and target vacuum; sample testing is recommended.
