u003cpu003eNon-woven bags, also known as non-woven bags. It is also one of the environmental protection bags, and it is also the most used environmental protection bag in the environmental protection bag. Many friends know non-woven bags. It can also be seen that there are some differences between some non-woven bags and non-woven bags, but it just can't be said, where are the differences. So, Shenzhen Textile, from the perspective of non-woven bag manufacturers, talks about some basic differences between non-woven bags. u003c/pu003eu003cpu003eFirst of all, let's talk about the material. are made of non-woven materials through stitching process or voltage wireless stitching process. The non-woven fabrics can be divided into ordinary non-woven fabrics, coated non-woven fabrics and spunlace non-woven fabrics. Ordinary non-woven fabrics are our most common. Non-woven fabric, also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. u003c/pu003eu003cpu003eu003c/pu003eu003cpu003eThe non-woven fabric is moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, recyclable, etc. Features. For example, polypropylene (PP material) pellets are mostly used as raw materials, which are produced by continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing. The production cost of ordinary non-woven bags is also relatively cost-effective, which is much more affordable than film-coated non-woven bags and spunlace non woven bags
. Many businesses, when purchasing large quantities of non woven bags, will choose to use ordinary non-woven materials to customize their own non-woven bags. u003c/pu003eu003cpu003eLaminated non-woven bags, compared to ordinary non-woven bags and spunlace non-woven bags, the positioning of customers is higher. Many products need film-coated non-woven bags to set off the quality and grade of the products. Especially for products such as jewelry and high-end clothing, it is particularly suitable to use laminated non-woven bags as packaging bags. Due to the high brightness of the film and the strong three-dimensional effect, the bag itself reveals a noble breath. In addition, film-coated non-woven bags are divided into bright film and dumb film. In ordinary words, one should be smoother and the other should be rougher. u003c/pu003eu003cpu003eSpunlace non-woven bags, relatively speaking, the above two bags are not so widely used. Spunlace non-woven bags are generally only used as inner packaging bags for products, or dust-proof bags. Because non-woven bags are moisture-proof, breathable, flexible and lightweight, many electronic products choose them as products. Inner packaging. u003c/pu003eu003cpu003eu003c/pu003eu003cpu003eThe above are all about the material difference of non-woven bags, and then I will talk about the production process of non-woven bags. As far as the current production process is concerned, it can be divided into two production processes, a sewing process and a voltage process. Sewing non woven bags is a more traditional manufacturing process, which is easy to understand. Just like making clothes, they are sewn with a sewing machine. However, due to the traditional production process, the production cost is a bit more expensive. Mainly expensive in labor costs. As we all know, many industries are expensive in labor. Therefore, if the process is not particularly strict, it is better to choose a voltage process. The voltage process can be said to be a new type of manufacturing process in the environmental protection bags industry. This is easier than sewing bags. However, the equipment for making the voltage process is not simple. Although, after adjusting the equipment, it is very fast to make the bag, but the person who operates the behemoth needs a very skilled person to do it. As far as the production speed is concerned, the voltage process is basically formed at a time, which can be said to be one per second, while the sewing process cannot produce one in a minute. This is the difference between traditional technology and current technology. Therefore, if you need to purchase non-woven bags in large quantities, it is recommended that you use voltage technology. u003c/pu003eu003cpu003eu003c/pu003e
