How it works

The DX-B3S uses servo indexing with photoelectric registration tracking and automatic web tension matching, handling PET/PE, BOPP/PE, aluminium foil and metallised laminates. Three-side seal, four-side seal, shaped, zipper and stand-up pouches are produced by changing tooling and station configuration.

Sealing temperature is controlled in independent zones, so seals stay flat without bubbles or weak spots. Optional punching, tear notch, corner cutting, spout insertion and inline inspection reduce the reliance on experienced operators and make short runs practical.

Selection advice: send your resin grade, target film width or pouch type, daily output and existing equipment. We confirm screw, die head, station count and support equipment from that — so a machine that looked cheap does not turn out to be the wrong one.

What decides the result

These six points are what actually show up in uptime, yield and labour cost, so they are worth comparing between suppliers.

Repeatable bag length

Servo haul-off with encoder feedback holds bag length run after run.

Registration tracking

Printed film is positioned precisely, so artwork and seals stay aligned.

Consistent seals

Zoned temperature control and even sealing pressure reduce leakers and complaints.

Fast changeover

Quick-change tooling and stored recipes keep small mixed orders economical.

Automation options

Punching, notch, corner cut, spout insertion and vision inspection can be added.

Safe to run and to service

Guarded stations, emergency stop circuit and grouped maintenance points.
