Roll-fed Square Bottom Paper Bag Machine

The EZ TECH China Roll-fed Square Bottom Paper Bag Machine equipped SIEMENS PLC system ensures that the machine can perform quickly and stably. This machine can process very thin paper, as well as produce paper bags very fast, thus this machine is especially suitable for  being applied in food industries.

Core selling points

Full-size coverage, handle both small and large bag types with one machine

From mini food takeout bags to large shopping paper bags, different sized square-bottom paper bags can be produced stably. There is no need to purchase additional equipment for different specification orders. One machine can cover most common paper bag sizes, and the equipment utilization rate is directly maximized.

Multiple bag bottom styles can be freely switched, adapting to various scenarios

Unlike traditional equipment that can only produce a single bottom type, the Roll-fed Square Bottom Paper Bag Machine supports the production of various different styles of square-bottom paper bags. Based on the order requirements, the bottom type parameters can be quickly adjusted. Without changing complex molds, it can produce bag types suitable for food, retail, gifts and other different scenarios, helping you easily handle more diversified orders.

High-speed and stable production, a powerful assistant for batch orders in the food industry

Equipped with Siemens PLC control system, the entire machine has strong synchronization in operation. During the production process, feeding, forming, cutting, and bottom sealing are all stable and smooth, and it can maintain a high-speed operation state for a long time. Even for thin oil-resistant paper and kraft paper commonly used in the food industry, it can produce stably without deviation and easily handle large-scale takeout bag orders for baking, snacks, etc.

Optical sensor precise deviation correction, small cutting error, high product consistency

Equipped with an optical detection device, it can real-time correct the cutting length. Even in a high-speed production state, the size of each bag can maintain a high degree of consistency, reducing the cost of manual inspection and rework, and the quality of the finished products is neat, with a low defect rate. The customer will receive bags of stable quality.

Full-process automation, significant reduction in labor costs

From reel feeding to finished bag collection, all processes are automatically completed by the equipment. There is no need for manual intervention in the intermediate links. A single line only requires 1-2 people to be on duty. Compared with the traditional semi-manual bag-making method, it can significantly reduce long-term labor costs and reduce errors caused by manual operation, and the production efficiency is significantly improved.

FAQ

Q1: Is it complicated to switch production between different-sized bags?

A: The operation is very simple. Adjustments to bag width, height, and bottom style can all be made on the touch panel without disassembling the machine or replacing the molds. The parameters can be switched in just a few minutes. Ordinary workers can operate independently after simple training and won't affect the production progress of the orders.

Q2: Will there be problems such as slipping during feeding or irregular shaping when producing thin food anti-oil paper?

A: No. The equipment has optimized feeding and shaping for thin paper. The tension control is stable, and it is combined with photoelectric correction. Even for food-grade anti-oil paper and thin kraft paper, it can feed smoothly, shape regularly, have a firm bottom adhesion, and avoid problems like glue separation or bottom leakage. It meets the usage requirements of food packaging.

Q3: How stable is the Roll-fed Square Bottom Paper Bag Machine during long-term continuous production?

A: The entire machine is equipped with a Siemens PLC control system, and the core components use durable components. The transmission system has strong synchronization. Even during long-term continuous operation, it can maintain stable production speed and accuracy, without any problems such as stalling, deviation, or uneven dimensions. It can easily handle rush orders during peak seasons.

Q4: Can the cutting accuracy be guaranteed? Will there be situations where the bags are of different lengths?

A: Yes. The equipment is equipped with a photoelectric detection and correction device, which will monitor and correct the cutting length in real time. Even during high-speed production, the size error can be controlled within a very small range. Each bag has a highly consistent size, and the finished product has a high degree of neatness, without the need for manual secondary screening.

Q5: Besides the food industry, can it also produce paper bags for other industries?

A: Yes. As long as the paper material and size are within the equipment's compatibility range, the parameters can be adjusted for production.
