Drawtape garbage bag on roll making machine
DTWFA-V
- Humanized interface panel controlled by digital computer will follow up whole working status provides perforation & sealing position adjustment and bag size setting without stopping the production, very easy operation.
- Sealing & cutting synchronized system to avoid sealing and perforation line not displacement.
- Automatic coreless rewinding system, applicable for HDPE, LDPE, and recycling film used.
- Adopting up-down heating, hot-cut system, tensionless sealing ensures strong sealing on bags.
- Infeed speed controlled by inverter, the speed of main machine and infeed are synchronized, no adjustment is required, very easy to operate it.
