There is an increasing demand for paper bags among retail stores while reducing the supply of plastic bags.
Some of the global retail stores operate our state-of-the-art high-speed paper bag production machine. Our system produces paper bags identical to the ones used by Trader Joe's and Whole Foods.
Variable size paper bag production requires many processes. Cut-out for an opening, making holes for handles, threading the handle string through the holes. The time loss from changing dimensions when the order quantity is small while required to create many different shapes could result in the unit cost increase and the overall production planning.
At NLI Group, we have focused on every impediment through the manufacturing process and successfully eliminated them with reliable sheet feed. Automating the opening cut-out, hole opening, round handle string install drastically reduced the processing time, thus lowering the unit cost. We have two variable-size paper bag models.
TS Series regulates the motion of various parts using servo motors. These motors synchronize moves when speed and size changes are significantly required reducing the adjustment downtime through settings by an NC (numeric control) system.
The system is compact, eliminating any power transferring shafts, making the workers stay at one location, improving work efficiency and safety.
The NC (numeric control) has the following features while the machine is running.
• Setting the position of the sheet to be fed
• Web guide sensor positioning
• Handle patching glue positioning
• Handle positioning
• Handle pressing servo to attach with the glue
• Handle centering
Automatically cuts an opening, open holes for string handles, threading strings. It can attach flexible and long handle strings up to 30 centimeters (11.8 inches). The capacity of 120 bags per minute.
