The kraft paper bag making machine project started with a simple inquiry from a German packaging company that wanted to expand its eco-friendly paper bag production capacity. The customer had been supplying paper shopping bags for retail stores and food brands in Germany. With increasing demand for sustainable packaging, their existing semi-automatic equipment could not meet delivery schedules during peak seasons. They needed a faster solution with stable quality, lower labor dependence, and compatibility with different kraft paper materials.
The customer contacted YG Machinery through the company website and shared their initial production requirements. They needed a machine capable of producing square bottom paper bags with twisted rope handles. The target production speed was above 100 bags per minute. The paper material range needed to cover common kraft paper between 50-140g/m², which follows widely used packaging material specifications in Europe. After receiving the inquiry, our sales engineer collected details about bag size, paper type, handle style, voltage requirements, and factory space.

First Communication and Requirements Analysis for Kraft Paper Bag Making Machine
During the first communication, the German customer provided samples of their existing paper bags. The samples included different sizes used for clothing stores, supermarkets, and takeaway businesses. The customer explained that their main challenge was not only speed but also production consistency.
Their previous process had several limitations:
- Manual handle attachment increased labor costs.
- Different operators created quality differences.
- Production changes required too much adjustment time.
- Peak orders created delivery pressure.
Before recommending a model, YG Machinery analyzed the samples carefully. The engineering team checked paper width, bag bottom size, handle position, and material thickness. Based on these details, we recommended the YG-FD220T kraft paper bag making machine because it could match the customer’s production range.
The customer arranged a video meeting with our technical team. During the meeting, engineers explained the working process step by step:
- Paper roll feeding.
- Printing mark tracking.
- Tube forming.
- Bottom folding and gluing.
- Handle production.
- Handle attachment.
- Final bag output.
The customer also showed their factory layout through video. This helped our engineers confirm installation space and machine placement before production.
Find the Right Model for Your Project
Selecting The Right Paper Bag Machine For Sale Configuration
After technical discussion, the customer requested several modifications. They wanted the equipment to handle multiple bag sizes without complicated operation changes. They also needed a machine suitable for long-term commercial production.
The final configuration was confirmed after several rounds of communication.
The selected solution included:
- Automatic paper feeding system.
- Rope handle production unit.
- Handle patch gluing system.
- PLC control system.
- Touch screen operation interface.
- Automatic speed adjustment.
- Safety protection system.
The customer compared several suppliers before making a decision. They focused on machine structure, production speed, after-sales support, and factory experience. The customer finally selected YG Machinery as their supplier because the technical communication process was clear and the machine configuration matched their actual needs.
The quotation included machine cost, spare parts, export packaging, technical documents, and installation guidance. After contract confirmation, the customer completed payment according to the agreed terms, and production officially started.
Building The Automatic Paper Bag Machine According To European Requirements
Production began after receiving the order. The engineering department prepared manufacturing drawings and checked every component before assembly.
The production process included:
- Steel frame manufacturing.
- Electrical system installation.
- Mechanical component assembly.
- Handle system adjustment.
- Software parameter setting.
- Full machine testing.
YG Machinery follows strict production procedures during manufacturing. Each key component is inspected before installation. After assembly, the machine runs through multiple tests to check speed stability, bag forming accuracy, and handle attachment performance.
For the German project, the machine was tested using similar kraft paper materials before shipment. Engineers adjusted the glue system, paper feeding tension, and handle position according to the customer’s bag samples.
The final test results showed:
- Production speed reached up to 220 bags/min.
- Paper weight range supported 50-140g/m².
- Handle production speed reached 150pcs/min.
- Automatic control system operated smoothly.
The customer received testing videos before shipment. They checked the bag samples and confirmed that the quality met their requirements.
Factory Inspection, Packing and Shipping of Kraft Paper Bag Making Machine to Germany
Before shipment, the customer requested a final online inspection. Our team connected through video and showed the complete machine operation.
The inspection covered:
- Machine appearance.
- Electrical cabinet.
- Moving parts.
- Handle making section.
- Finished bag samples.
- Spare parts package.
After approval, the machine was prepared for export.
Because the equipment contained precision mechanical components, YG Machinery used professional export packaging. The machine was protected with waterproof materials and fixed inside the wooden case to avoid movement during transportation.
The equipment was loaded into the container and shipped from China to Germany. During transportation, our team kept in communication with the customer and provided shipping updates.
After the machine arrived at the customer’s factory in Germany, engineers guided the installation through online video support. The customer completed mechanical positioning, electrical connection, and initial testing with our instructions.
Paper Bag Production Line Started Commercial Operation
After installation and adjustment, the machine entered official production.
The customer’s factory mainly produced kraft shopping bags for retail customers. Compared with their previous production method, the new equipment improved production efficiency and reduced manual operation requirements.
