Poly Courier Bag Making Machine

The poly courier bag making machine is dedicated to hot cutting, edge sealing and bag fabrication of polyethylene film, available for both printed and non-printed materials. Standard configurations include programmable automatic length adjustment, color register tracking, automatic glue severance, and emergency stop mechanisms triggered by release film or base film rupture. It is also fitted with automatic tension regulation and robotic arm clamping structure, alongside the patented first-out sorting function. With three overall patents, poly courier bag making machine represents the most sophisticated and optimal solution for express bag production.

Poly courier bag making machine has the following advantages:

1. Loading part: ① Rapid cylinder actuation drives the lifting structure, effectively cutting wasted feeding time. It features solid load-bearing capacity and keeps film steady during production, making automation simple to implement. Designed for film rolls with up to 750mm unwinding diameter, it removes manual lifting work to boost overall productivity. ② No-material detection enables automatic shutdown for the bag making machine. Once the film breaks or runs short, the machine ceases operation to keep unqualified products off the production line. It saves time and labor by removing the need for repeated material re-threading. We offer two shutdown solutions: one-touch Mode A and roll diameter calculation Mode B.

2. Host part: The control system adopts high-grade local PLC hardware, paired with our self-developed exclusive programs. Users can finish parameter setup with ease via the touch screen. It keeps a close watch on production and supports electronic fault checking. Analog quantity synchronous feeding ensures the feed rate matches other procedures steadily. Front and rear double servo motors realize stretch-free film transportation. One servo controls the combining part of release film and raw film, and the other runs the rubber roller behind the cutting blade. Precise adjustment on film length and speed ensures accurate cutting and hot pressing.

3. Discharge section: The computer carries out automatic counting for single items and production batches. Custom alarm points for length or quantity can be configured to initiate auto stop and standby status. You may set dwell time directly on the machine screen.
