Roll Fed Square Bottom Paper Bag Machine (Die Cut Handle Patch Application Unit) Series

The SBH-W series roll fed square bottom paper bag machine is based on the SBH series and is designed to manufacture square bottom paper bags from paper roll in blank or printed designs. A die cut handle device has been added to the manufacturing line, so that a handle can be added to the bag. Side gluing, tube forming, die cut handle, tube cutting, bottom creasing, bottom gluing, bottom forming and final product out feed can all be completed in a single run, making this ideal equipment for food bags, shopping bags and other common paper bags.

Sunhope is the first company in China to design and produce a die cut handle patch application unit, which can be added to the SBH290W, SBH330W, and SBH330BW machines to produce die cut handle bag inline with reinforced patches using paper or film materials.

1. The roll fed square bottom paper bag machine is equipped with a Japanese Mitsubishi servo system and SICK photocell for correction, so that users can accurate track printed material, and minimize adjustment and pre-set times.
2. It is equipped with a Mitsubishi electric control system and Mitsubishi motion controller (CPU). This achieves an integration of an optical fiber in order to achieve a high speed and high precision, motion control and production flow test. With a touch screen display, the operation functions are clear, and feature a great human to machine interface.  
3. Equipped with an Italian RE tension system and German BST WEB guiding system, the machine can reduce waste and improve efficiency.  
4. The patch length and width are adjustable. Patch position can be adjusted.
