The main material of non-woven bags is a non-woven fabric, which directly uses polymer chips, short fibers or filaments to form a soft, breathable and flat structure through various web forming methods and consolidation technologies. New fiber products. Non-woven bags have the advantages of low price and good quality, environmental protection and practicality, wide application, prominent advertising position and so on. The products produced by this project have a variety of styles and have very broad application prospects. Their main uses include strong environmentally friendly shopping bags. Traditional plastic shopping bags are thin and easily damaged in order to save costs. In order to make them stronger, they will inevitably cost more. The most important thing is that plastic bags are not easily decomposed, which puts a lot of pressure on the increasingly severe environmental situation. Non-woven shopping has solved many of the above problems due to its strong toughness, not easy to wear, and easy to decompose. The non-woven shopping bag is covered with an ultrasonic sealing welding machine to make it more robust, waterproof, good in hand, and beautiful in appearance.
