Product advantages

The sheet-fed design of the machine significantly improves production efficiency.

The advanced pre-stacked paper feeding device of the Sheet-fed Square Bottom Paper Bag Machine supports continuous and uninterrupted feeding, avoiding the frequent paper changing issues of traditional equipment. The production efficiency has been greatly enhanced. Combined with a stable transmission system, it can maintain efficient operation for long-term continuous production, reducing downtime for maintenance and debugging, and enabling smooth production of peak season orders.

Compatible with dual adhesive systems, stable processing of multiple types of paper

Equipped with a complete water glue and hot melt glue dual application device, it can automatically adjust the type of glue and the amount of coating according to the paper type. Whether it is ordinary kraft paper or coated coated board paper, it can ensure firm side and bottom adhesion, without problems such as delamination or edge warping, and the finished bags have strong durability.

Two bag production capacity, expanding business coverage

The equipment supports the production of two different types of square bottom paper bags without the need to replace complex molds. By adjusting parameters, the production mode can be switched. One machine can meet the customized needs of different customers, significantly expanding the business scope and creating more profit space for customers.

High-precision forming process, regular and stiff bag shape

When producing the Sheet-fed Square Bottom Paper Bag Machine, we adopted an integrated process of line pressing, side bonding, cylindrical forming, and bottom forming. The bag body is formed precisely, the bottom is flat and firm, the bag shape is stiff and not prone to sagging, has strong load-bearing capacity, and heavy objects will not cause deformation or delamination at the bottom. The finished products have high consistency and low defective rate.

Full-process automated production, significant reduction in labor costs

From sheet-fed paper feeding to the output of finished bags, all process steps are automatically completed by the equipment. The multiple manual processes such as pressing, folding, and bottom bonding are omitted. Only a small number of personnel need to be on duty for one line, significantly reducing labor costs, it reduces errors caused by manual operation and improves production stability.
