In the field of paper bag production, the types of paper bag machines are mainly divided according to the paper feeding method, degree of automation and production products. Different types of paper bag machines have obvious differences in production efficiency, types of processable paper bags and applicable scenarios (there is no machine in the world that can make all types of paper bags). The core can be divided into four categories: roll-fed paper bag machine, fully automatic roll fed paper bag machine, sheet fed paper bag machine, and roll to sheet paper bag machine. Each type of machine corresponds to the production needs of paper bags of different grades and uses.
1. Roll Fed Paper Bag Machine: Focusing on Basic General Paper Bags
Roll fed paper bag machines are entry-level paper bag production equipment, specializing in producing basic bag shapes such as sharp bottom bags and square bottom hand paper bags. These machines utilize a continuous roll-fed system and complete bag formation through multiple process steps.
Production Process:
Paper feeding → Paper perforating → Paper tube inserting →Cutting to length → Bottom folding → Gluing and sealing →paper bag collecting
The entire process is continuous, with production speeds reaching 200-300 bags/minute.
These paper bags are primarily used for everyday food products such as snacks, treats, coffee beans, bread, candy, and pastries etc.
2. Fully Automatic Roll Fed Bag Machine: Specializes in paper bags with handles, suitable for daily use.
Based on the basic roll-fed bag machine, the fully automatic roll-fed bag machine adds automatic paper handle production and installation capabilities, achieving fully automated production of paper bags with handles.
Main production process: Roll-fed > Paper printing (optional) > Paper gluing > Paper handle pasting > Paper bag gusset forming > Paper bag cutting > Paper bag bottom opening > Paper bag bottom gluing > Paper bag bottom gluing > Paper bag bottom sealing > Paper bag output
The more workflows involved, the more expensive the machine.This type of paper bag is primarily used for daily shopping: supermarkets, markets, and takeout.
3. Sheet fed paper bag machine: Focus on high-end customized paper bags
The core difference between the single-sheet paper bag machine and the first two types of models lies in the "paper feeding method" - it uses "sheet paper" as raw material (the paper needs to be cut into single sheets that meet the unfolded size of the paper bag in advance, and can be pre-processed with lamination, hot stamping, embossing, etc.). It is mainly used for the production of high-end tote paper bags and high-end paper bags with handles. It is the preferred equipment for companies focusing on brand customization and high-end packaging business.
The production of high-end paper handbags, intended for luxury goods, high-end cosmetics, and gift items, demands high levels of appearance, printing precision, and process complexity. White cardboard and specialty papers are often used, and surface treatments such as lamination (for waterproofing, wear resistance, and enhanced gloss), hot stamping (for metallic logos), embossing (for textures like leather grain and stripes), and UV printing (for enhanced three-dimensional design) are possible. Sheet-fed paper bag machines stack pre-treated sheets on the machine's feeder.
Main production process: Automatic single sheet feeding > Paper gluing (optional) > Reinforce top card or paper handle pasting (optional) > Top folding > Paper bag tube forming > Paper bag bottom opening> Automatic bottom card instert (optional) > Bottom gluing > Bottom sealing > Paper bag output.
When producing high-end paper bags with handles, 100-190gsm kraft paper is typically used to meet environmental and recyclable requirements. By connecting the handle production unit and the handle inserting unit in series within the paper bag machine, the handles can be made with either round or flat rope, achieving integrated production. Compared to paper bags produced by fully automatic roll fed paper bag machines, these bags can be made with thicker paper, resulting in a more textured feel, richer colors, and a fold-over top, making the bags more aesthetically pleasing and able to withstand greater weight.
4.Roll to sheet fed paper bag machine
The roll to sheet paper bag machine was independently developed by Zenbo Intelligent Machinery Co., Ltd. in 2019 and was awarded the title of China's first major technical equipment. The first generation roll to sheet paper bag machine has a dual paper feeding function and can quickly switch between the two paper feeding modes within 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 reel machine. In terms of efficiency, it is the same as the reel machine, and in terms of function, it is more powerful than the reel 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 8000PCS/hour, which can greatly improve the production efficiency for users.
When choosing a machine, companies should consider their order structure (batch size, degree of customization), product positioning (basic vs. high-end), and cost budget. Only equipment that matches their business needs can improve production efficiency while ensuring product competitiveness and profitability.
