01

Check applicable objects first

Back seal or three-side seal bags formed online from roll film; bag width, length, seal edges, and tear notch confirmed per finished bag sample

02

Packaging material and process must match

Composite roll film suitable for bag making and heat sealing; film width, thickness, friction, heat seal layer, and print registration confirmed per film sample; roll film unwinding, bag forming, longitudinal or side sealing, metering filling, cross sealing and cutting, and bag discharge

03

Optional modules are not standard

Optional: suck-back drip-proof, temperature maintenance, stirring, easy-tear notch, coding, gas flushing, inspection, and finished bag conveying.

Steps from sample confirmation to delivery

First determine bag shape, then match metering and sealing

The more complete the samples, packaging materials, and site information, the easier to determine equipment route, changeover scope, and line integration boundaries.

Determine bag type and roll filmConfirm back seal or three-side seal, bag width and length, heat seal layer, and print registration.
Complete material metering trialSelect pump, valves, filling nozzle, drip-proof, and cleaning structure.
Coordinate filling and sealing/cuttingAvoid material contamination of cross seal and confirm bag length, sealing, and cutting.
Continuous acceptance based on materialCheck metering, bag forming, sealing, cleaning, and film/material change.
