Roll To Sheet Feeding Paper Bag Making Machine Develop History
No.1:What is a roll-to-sheet paper bag making machine?
The roll-to-sheet paper bag making machine is a paper bag machine that realizes the process quality of sheet-type eco-friendly paper bags after servo slitting by the way of roll feeding.
No.2:Origin of roll-to-sheet paper bag machine
The roll-to-sheet paper bag machine was independently developed by Zhejiang Zenbo Intelligent Machinery Co. Ltd. in 2019, which was honored as China's first set of major technical equipment. Zenbo owns the invention patent of this product, and based on this, it has expanded and developed two series of machines to respond to the diversified market demand.
（1） Dual feeding functions of roll-to-sheet paper bag making machine (Roll and Sheet Feeding)
（2） High speed roll-to-sheet paper bag making machine
（3） T series high speed roll-to-sheet paper bag making machine
No.3:The difference between the roll-to-sheet paper bag machine and the roll-fed paper bag machine
The roll-fed paper bag machine uses roll paper as raw material. The process of making a paper bag is cutting off the paper after gluing, then opening the bottom, gluing the bottom, and then outputting paper bags.
The roll-to-sheet paper bag machine will slit the roll paper into sheets after roll feeding, having the top folding process, so as to realize the integration of the bag making process.
Therefore, when compared with the roll machine, the roll-to-sheet paper bag machine has the following advantages:
(1) Suitable for paper with higher grammage.
(2) Can produce fine paper bags with top folded and handles.
(3) Paper bags without a double folding line on the bag face.
(4) Handle unit with full servo cut-off function. Can save 6-8 kg of handle material waste per day, saving production costs.
No.4:Roll to sheet feeding paper bag making machine develop history
Zenbo is the first to develop a dual feeding mode roll-to-sheet paper bag machine. The machine can choose two modes of feeding paper to produce paper bag machine, the first is to use roll paper as raw material to produce paper bags in roll-to-sheet form. In the second mode, the servo slitting unit is moved out through the guide rail to quickly change the machine into sheet feeding mode to produce paper bags with sheet as raw material.
The dual feed modes roll-to-sheet paper bag machine can quickly complete the switching of the two feeding modes in 15 minutes so that the machine can adapt to the paper after flexo printing in the roll feeding mode; the paper after offset printing suits the sheet feeding mode. This reduces the number of paper loading and paper change downtimes, reducing labor intensity. However, the maximum speed of this machine is 80pcs/min, which is not a small gap with the speed of the roll paper bag.
Therefore, Zenbo developed a high-speed roll-to-sheet paper bag machine in 2023. This model is specialized in single roll feeding mode and is equipped with a top folding process, through the design of a variety of integrated structure and components, the operating speed of the roll-to-sheet paper bag machine is greatly enhanced. The maximum speed of the machine is 100pcs/min, the same speed as the roll fed paper bag machine. In terms of efficiency, it is the same as the roll machine, and in terms of function, it is more powerful than the roll feeding paper bag machine, so it is favored by the users.
Knowing the importance of independent innovation, Zenbo officially launched the T series of high-speed paper bag machines at the 2025 Beijing Exhibition. This paper bag machine is also equipped with top folding craft interchanging; the whole machine adopts a linear guide rail, which is more accurate and easier to control when adjusting the size of the paper bag. It also has a larger range of bag sizes (please contact us for more advantages). The maximum production speed of the T series machine can reach 9000PCS/hour, which can greatly improve the production efficiency for users.
Zhejiang Zenbo Intelligent Machinery Co. Ltd. is constantly leading the progress and development of paper bag machines, exploring and perfecting the intelligent way of making paper bags, and practically practicing the enterprise business philosophy of “Achieve customer success, customer first.” Taking the user's demand as the core, we provide in-depth customized service for global users.
