Flat and Satchel Paper Bag Making Machine XKJD3-250/350
Automatic Roll-fed Paper Bag Making Machine for Paper Food Bag
XKJD-270 automatic roll-fed paper bag making machine is a high-speed model designed for manufacturing flat and satchel paper bags (sometimes also known as V-bottom paper bags or sharp bottom paper bags). This flat and satchel paper bag making machine can automatically accomplish the entire process in one pass, including paper roll unwinding, pre-puncturing, side gluing, tube forming, cutting, bottom folding, bottom gluing and final bag collection. The paper bag machine is featured by stable running, high speed, low power consumption and high production efficiency. By simply equipping with in-line printer or window patching unit, this model of paper bag making machine can also manufacture printed flat paper bags or satchel paper bags with clear windows. This flat and satchel paper bag making machine is an ideal solution to manufacture paper bread bags, paper sandwich bags, as well as fast food paper bags for KFC and McDonalds.
