Non-woven Bag Making Machine

The non-woven bag making machine is suitable for non-woven fabrics, which can process non-woven bags of different specifications and shapes, waistcoat bags, handbags, leather bags, etc.

In recent years, new industry bags include non-woven fruit bagging, plastic turnover basket bagging, grape bagging, apple bagging, etc. The machine integrates electromechanics into one, using touch screen operation.

Introduction of non-woven bag making machine

With step-by-step fixed length, photoelectric tracking, accurate and stable. Automatic counting can set counting alarms, automatic punching and other industrial control devices, so that the finished products of the production are tightly sealed and beautifully cut. High-speed effect is a high-quality and environmental-friendly bag-making equipment that you can use with confidence.

According to the machine structure and operation form, it can be divided into: single machine and automatic production line. The single machine has the advantages of economical price, convenient use and simple maintenance. Multiple units can be combined to form a production line.

Principles and Characteristics

The non-woven bag making machine feeds powder (colloid or liquid) into the hopper above the packaging machine in real time. The introduction speed is controlled by the photoelectric positioning device. The roll of sealing paper (or other packaging materials) is introduced into the lapel former by the guide roller. After being bent, the longitudinal sealer overlaps and becomes cylindrical. The material is automatically measured and filled into the finished bag. The cross sealer pulls the bag barrel down intermittently while performing heat seal cutting. Finally, a flat bag with three sides sealed by overlapping longitudinal seams is formed to complete the sealing of one bag.

Non-woven Bag Making Machine


  • The use of ultrasonic welding eliminates the need for needle thread and saves the trouble of frequent needle thread changes. Without the broken thread joints of traditional thread stitching, the textile can also be cleanly cut and sealed locally.The stitching also played a decorative role. Strong adhesion, can achieve waterproof effect. The embossing is clear, and the surface has a three-dimensional relief effect. The working speed of the product is good and more beautiful. Quality is guaranteed.
  • Using ultrasonic and special steel wheel processing. The sealed edges are not cracked, do not hurt the cloth edges, and have no burrs or curling.
  • No preheating is required during manufacturing, and continuous operation is possible.
  • The operation is simple and not much different from the traditional sewing machine operation method. Ordinary sewing workers can operate.
  • low cost. It is 5 to 6 times faster than traditional machines and has high efficiency.

Technological Development

  1. Basic Process

Loading (non-woven fabric coil) → folding → ultrasonic bonding → cutting → bag making (punching) → waste recycling → counting → stacking

This process can be fully automated. Only 1 ~ 2 people are required to operate. The multi-functional full-automatic non-woven bag making machine can adjust the production speed and product size using touch screen operation within a certain range, equipped with stepped fixed length, photoelectric tracking (accurate and stable operation), automatic counting (counting alarm can be set) , Automatic punching and other industrial control devices. At the same time, in order to further achieve the effect of energy saving and environmental protection, it has a function of recovering residual materials in the production process, and automatically collects the waste materials left in the production process, which is helpful for secondary use, reduces labor intensity, and increases work efficiency.

  1. Features of automatic non-woven bag making machine

Advanced design technology, fast production speed and high efficiency. It can process environmental protection non-woven bags with different specifications and different shapes. It has the characteristics of good quality and high bonding strength.

Non-woven bag making machine application industry

The packaging industry includes: environmental protection bags, gift bags, shopping bags, advertising bags, non-woven bags, gift bags, non-woven hand bags, non-woven cloth hanging bags, cosmetic bags.

The clothing industry includes: suit bags, advertising apron.

The home appliance industry includes non-woven computer bagging, TV bagging, air-conditioning bagging, washing machine bagging, dust-proof cover bagging and other environmentally friendly non-woven products.

Production Process

Non-woven bags generally use screen printing technology, which is often referred to as “silk screen printing”, which has always been a printing process commonly used by many manufacturers. Generally, they are printed manually, so the color control in the process is not easy to control, so many new non-woven printing methods have emerged. Here we introduce the current mainstream in the market:


It is named because it uses water-based elastomers as printing media. It is more common in textile printing. When printing, mix the color paste and water-based elastic rubber together. No chemical solvent is needed when washing the printing plate, it can be washed directly with water. It is characterized by good coloring power, strong hiding power and fastness, washing resistance, and basically no odor.

Gravure printing

The finished product processed in this way is usually called a laminated non-woven bag. This process is divided into two steps, that is, the traditional gravure printing process is used to print the graphics on the film, and then the film printing process is used to composite the printed film on the non-woven fabric. Generally, nonwoven bags printed with large-area color patterns adopt this process. It is characterized by exquisite printing, the whole process is produced by machine, and the production cycle is short. In addition, the product has excellent waterproof performance, and the durability of the finished product is better than that of non-woven bags produced by other processes. The membrane is available in two options: bright and matt. Matte membrane has a matte effect! The disadvantage is that it conflicts with the concept of environmental protection, because the membrane is difficult to degrade.

Thermal transfer printing

Thermal transfer printing belongs to special printing in printing! The method requires an intermediate medium, that is, the picture and text are first printed on the heat transfer film or heat transfer paper, and then the pattern is transferred to the non-woven fabric by heating the transfer equipment. The medium commonly used in textile printing is thermal transfer film. Its advantages are: exquisite printing, rich hierarchical version, comparable to photos. Suitable for small area color image printing. The disadvantage is that the price is high and the printing cost is high.
