Fixed Size Paper Bag Mass Production System with and without paper handles
In today's world, people are increasingly aware of the importance of environmentally-friendly lifestyles. This has led to a growing demand for paper bags among retail stores, as they seek to reduce their reliance on plastic bags. Many global retail stores have opted to use our state-of-the-art, high-speed paper bag production machines, which can produce paper bags that are identical to those used by popular chains such as Trader Joe's and Whole Foods.

Variable Size Paper Bag Mass Production System
The production of variable-sized paper bags requires several processes, including creating an opening, making handle holes, and threading the handle string through those holes. However, changing dimensions for small order quantities and creating various shapes can lead to increased unit costs and affect overall production planning.
At NLI Group, we have identified and eliminated these impediments through reliable sheet feed and automation of the opening cut-out, hole opening, and round handle string installation. This automation has drastically reduced processing time, leading to lower unit costs. We offer two variable-sized paper bag models.
Roll Stand Fed Type
TS Series
The TS Series utilizes servo motors to regulate the motion of various parts. These motors synchronize moves when significant changes in speed and size are required, thereby reducing the adjustment downtime through settings by an NC (numeric control) system. Additionally, the system is compact, eliminating any power transferring shafts and allowing workers to remain at a single location, which improves work efficiency and safety. While the machine is running, the NC system provides the following features:

• Setting the position of the sheet to be fed
• Positioning the web guide sensor
• Positioning the handle patching glue
• Positioning the handle
• Servo-controlled handle pressing to attach it with glue
• Centering the handle

Sheet Fed Type
N300 Series: The servo-controlled sheet feeder enables stable feed at any speed and can adjust dimensions on-the-fly, making it suitable for producing a variety of sizes in small quantities. In addition, the system automatically cuts an opening, opens holes for string handles, and threads strings, allowing it to attach flexible and long handle strings of up to 30 centimeters (11.8 inches) in length. With a production capacity of 120 bags per minute, it is a highly efficient and reliable solution for bag production.

Sheet Feeding with Reel Unwinder Type
RS Series: The machine has succeeded in cutting the sheet roll directly, significantly reducing material waste. It is optimized for producing large quantities of up to 10,000 bags per roll and is capable of automatically cutting out the bag opening, making holes for handle strings, and threading rounded handle strings. With a production capacity of 100 to 120 bags per minute, it is a highly efficient solution for bag production.
