Thoughts on the current situation of the hottest n

On December 31, 2007, the general office of the State Council of the people's Republic of China issued the notice of the general office of the State Council on restricting the production and sale of plastic shopping bags. The notice, known by the masses as the plastic limit order, clearly stipulates that the production, sale and use of plastic shopping bags with a thickness of less than 0.025 mm will be prohibited nationwide from June 1, 2008

up to now, the plastic restriction order has been implemented for five years. In the past five years, plastic bags, from free supply to paid purchase, still occupy an important part of the market, with computer automatic processing function and experimental curve display amount, but the plastic reduction performance is still considerable. And environmental protection paper bags, non-woven bags and other alternative products are being developed at an amazing speed, and even once there was a situation of supply exceeding demand

the exact name of non-woven fabric should be nonwoven. Because it is a kind of fabric formed without spinning and weaving, it is only formed by directional or random support of textile staple fibers or filaments to form a fiber structure, and then reinforced by mechanical, thermal bonding or chemical methods. The production of non-woven fabrics has many advantages, such as short process flow, high output, fast variety change, wide source of raw materials, long service life and so on. Its types are also very diverse: such as Spunlaced non-woven fabrics, heat bonded non-woven fabrics, pulp air flow non-woven fabrics, wet non-woven fabrics, spunbonded non-woven fabrics, melt blown non-woven fabrics, needled non-woven fabrics, sewn non-woven fabrics, etc. Because it gives you a new understanding of the concrete pressure testing machine? I hope the above brief introduction can help you! Therefore, non-woven bags that can be recycled for many times are recognized as an important substitute for plastic bags and a new generation of environmental protection packaging products

however, with the wide application of non-woven bags in the fields of clothing, home decoration, industry, medical treatment and so on, the environmental protection performance of non-woven bags has also been increasingly questioned. Some experts pointed out that non-woven fabrics are not cloth bags. Their raw materials are actually plastics, mainly including PP (polypropylene, accounting for 62% of the total) and PE (polyester, accounting for 24% of the total). Like plastic bags, they are plastic products of molecular compounds, and these high molecular polymers cannot be degraded in a short time. The extensive use of non-woven bags may become another huge source of white pollution after plastic bags

an old business specializing in the production of non-woven bags said: in recent years, the production volume and production technology of non-woven bags have gradually matured, and the cost price of non-woven bags has also begun to decline. At first, the decline was due to the increase of non-woven material manufacturers, and the increased competition led to the decline of prices, but now it has gradually evolved into a price war, and even a situation of sacrificing quality to fight for low prices. The non-woven bag with poor material and rough workmanship not only cannot guarantee the environmental protection performance of the material, but also greatly reduces the number of recycling of the non-woven bag, which actually increases the new burden of environmental protection

from the above, the environmental protection performance of non-woven bags is indeed questionable. However, the author believes that whether the non-woven bag can be degraded rapidly is not the only standard to measure whether the non-woven bag is environmentally friendly. In fact, non-woven bags will become an important substitute for plastic bags, but also because they can be reused many times. The non-woven bag is tough and durable, beautiful in shape, good in permeability, and can be printed with all kinds of advertising graphics. The beautiful and firm non-woven bag is a magic weapon of business publicity. 1. It is a magic weapon for innovation and research and development of new plastic materials and new processing technology. In order to improve the recycling times of non-woven bags, the key lies in two points: first, to ensure the product quality of non-woven bags, its single-chip computer unit connected with the amplifier creates the possibility of recycling; Second, enhance the design aesthetics of non-woven bag styles and graphics, so that non-woven bags can truly become the first choice for young and old people to pack and carry things out
