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 SBH330W, and SBH330BW machines to produce die cut handle bag inline with reinforced patches using paper or film materials.
