With the increasing scarcity of global resources, energy conservation and emission reduction has become the theme of the world. After the issuance of our “plastic restriction order”, non-woven bag making machines have become popular with their advantages of environmental protection, beauty, low price, wide use, etc. The reason is that non-woven bag can not only be used for many times, not only has the high bearing characteristics of plastic bags, but also is environmentally degradable.
The prospect of becoming a new favorite of the market is promising
In developed countries, non-woven bag making machine has been widely used. In China, environment-friendly non-woven fabric bags have the trend of replacing polluting plastic bags in an all-round way, and the domestic market prospects continue to be promising! Since the implementation of the “plastic restriction order”, it has been very difficult for supermarkets to see a large number of municipal people carrying things home in plastic bags. And the environment-friendly shopping bags made of different materials have gradually become the “new favorite” of modern citizens.
It can use ultrasonic welding to avoid the use of needles and threads, which saves the trouble of changing needles and threads frequently. There is no broken thread joint of traditional suture, and it can also cut and seal the textiles cleanly locally. The sewing also plays a decorative role. With strong adhesion, it can achieve waterproof effect, clear embossing, and more three-dimensional relief effect on the surface. With good working speed, the product is more high-end and beautiful, and the quality is guaranteed.
The characteristics of non-woven bag are compared with the traditional plastic handbag. The non-woven bag making machine produces bags with a longer service life and more extensive uses, which can be used as non-woven shopping bags, non-woven advertising bags, non-woven gift bags, and non-woven storage bags. However, compared with non-woven bag, plastic bag has lower price and better waterproof and moisture-proof performance, so they will keep abreast and cannot be completely replaced by non-woven bag. Therefore, plastic film bag making machine and non-woven fabric bag making machine will coexist for a long time.
Technology upgrading
Ultrasonic technology was originally used to process mattresses and bedspreads in the textile industry, but now it has been widely used in the non-woven fabric industry. Ultrasonic energy belongs to mechanical vibration energy, with a frequency of more than 18000Hz. Beyond the range of human hearing, it can be expanded to read: non-woven bag making machine, circular loom, four column hydraulic machine, intaglio printing machine, slotting machine and air cooler have a wide range of wavelengths to choose from. When applied to bonding thermoplastic materials, such as non-woven fabrics, the frequency usually used is 20000Hz.
The full-automatic non-woven fabric bag making machine, compared with the traditional needle type wire sewing, uses ultrasonic bonding to avoid the use of needles and threads, and eliminates the thread changing process. There is no broken thread joint of traditional thread sewing, and it can also perform clean local cutting and sealing of non-woven fabrics. It has a fast working speed, and the sealing edge does not crack, does not damage the cloth edge, and has no burr or curl. At the same time, ultrasonic bonding effectively avoids the problems of fiber degradation caused by thermal bonding, the porosity of materials affected by the adhesive layer, and delamination caused by the impact of liquid.
Ultrasonic bonding equipment is mainly composed of ultrasonic generator and roller. The main components of ultrasonic generator are horn, power supply and transformer. Horn, also known as radiation head, can concentrate sound waves on a single plane; The roller, also called anvil, is used to collect the heat released from the horn of the ultrasonic generator. The bonded materials are placed between the ultrasonic generator “horn” and the roller for continuous operation, and are bonded together under low static force.
