For a long time, non-woven bags as a new, convenient, environmental protection of new bags to the thousands of households. But recently, some people have questioned whether non-woven bags are really environmentally friendly, here, to discuss this issue.

Generally speaking, whether a material is environmentally friendly depends on whether it has two prerequisites:
1. It can be used many times.
2. After repeated use, the waste of the material will not have adverse effects on the environment.
From the above two points of view, non-woven bags produced by non woven bag making machine can meet the concept of environmental protection products.

First of all, non-woven bags can basically be reused many times. Second, the raw materials used in the production of non-woven bags are non-woven fabrics, non-woven fabrics are relatively easy to be naturally degraded. Therefore, after the non-woven bags are discarded, the waste will not cause great harm to the environment.

Although the non-woven bag fully meets the standards as an environmental protection bag, we should not ignore whether the production process of non-woven bag raw materials also meets the requirements of environmental protection. The raw materials of non-woven fabrics are mainly polypropylene, and polypropylene is a kind of petroleum industrial products. In other words, the raw materials of non-woven bags and plastic shopping bags are all from petroleum resources. On the other hand, the production process of non-woven fabrics is also not completely green and environmental protection. If the production process of non-woven fabrics is not strictly controlled or poorly managed, it will also discharge a large number of industrial wastewater and industrial waste gas which will pollute the environment. This is also contrary to the idea of environmental protection. Therefore, in this sense, non-woven bags from bag making machine can not be considered as an environmental protection bag.

Zhengwei Machinery as a non woven bag making machine manufacturer in the industry, its non-woven bag making machine has many good quality characteristics such as fast production speed, short process, high output, and so on. The products include three-dimensional bag machine, flat bag machine, waistcoat bag, socket bag and full-automatic non-woven bag machine and so on.

Five characteristics of non woven bag making machine:
1. The use of ultrasonic welding, needle-free stitching, eliminating the trouble of frequent needle change, there is no traditional thread stitching broken joint, but also for textiles neat local shearing and sealing. At the same time, the stitching also plays a decorative role, strong adhesive force, can achieve waterproof effect, clear embossing, surface more with three-dimensional relief effect, fast working speed, good product effect more high-grade beauty; quality assurance.
2. Using ultrasonic and special steel wheel processing, the sealing edge does not crack, does not damage the fabric edge, and there is no wool edge, crimping phenomenon.
3. Manufacturing without preheating, continuous operation.
4. The operation is simple, and the traditional sewing machine operation method is not much different, ordinary sewing machine can operate.
5. Low cost, faster than traditional bag making machine to 5 to 6 times, and high efficiency.

There are two ways of producing nonwoven bags at present.
1. The traditional stitching.
2. The new ultrasonic wireless suture.

The traditional stitching method refers to the use of traditional sewing machine (automatic or semi-automatic) sewing with chemical fiber thread, this method has obvious advantages: economic, quick, no need to add any equipment can successfully complete the transformation of the factory; of course, this production method has its obvious drawbacks: the traditional sewing method must be The use of needles and threads, usually produced from chemical fibers, in the degradation process, non-woven cloth can be completed in only three to five years, and chemical fiber yarn needs 30 to 50 years, making the non-woven bag of environmental protection capacity greatly reduced.
