Application of new technology in non-woven bag industry

Non-woven bags are produced by non-woven bag making machines with non-woven fabrics as raw materials, without any auxiliary materials and solvents added, so it is also a green product. Non-woven bag production equipment has two types of equipment: automatic non-woven bag machine and ultrasonic lace machine (semi-automatic non-woven bag machine). The automatic non-woven bag machine is highly automated and efficient. It is mainly used for the production of flat bags, side-inserted bags, and bottom-inserted bags. Therefore, it is widely used in large non-woven bag manufacturers with fixed orders. The current non-woven bags are still based on family workshops, and non-woven bags are processed according to customer requirements. In these factories, automatic non-woven bag machines are not very practical, and most of them use semi-automatic production equipment. The working principle of the ultrasonic lace machine is to use high-frequency oscillation to transmit sound waves from the welding head to the welding surface of the work object, instantly causing the work object molecules to friction and reach the melting point of the plastic, thereby completing the rapid dissolution of solid materials and completing the welding. The joint strength is close to that of a whole piece of continuous material. As long as the joint surface of the product is designed to match, there is absolutely no problem with complete sealing. In the process of making non-woven bags, the ultrasonic lace machine has two purposes: Non-woven bag seaming: the use of ultrasonic welding, eliminating the need for needles and threads, eliminating the trouble of frequent needle changes, and no broken thread joints like traditional stitching , It can also perform neat partial cutting and sealing of non-woven bags. Stitching also plays a decorative role. It has strong adhesion, can achieve waterproof effect, clear embossing, more three-dimensional relief effect on the surface, fast working speed, good product effect and high-end beauty; quality is guaranteed. Hand strap production: connect the ultrasonic lace machine and a shearing machine together, and set the ultrasonic lace machine to automatic, which can automatically make the hand strap. Ultrasonic lace machine (semi-automatic non-woven bag machine) is widely used in packaging industry, clothing industry, beauty industry, service industry, home appliance industry, non-woven clothing, office supplies, toy industry, etc. Used to make environmental protection bags, gift bags, shopping bags, advertising bags, non-woven bags, gift bags, non-woven handbags, non-woven clothes bags, cosmetic bags, suit bags, advertising aprons, non-woven computer covers , TV sets, air conditioner sets, washing machine covers, dust cover covers and other environmentally friendly non-woven products.
