Development prospects of non-woven bags

　　 Although the "plastic restriction order" has brought the environmentally friendly non-woven bag industry into a period of ultra-fast growth, the number of competitors in the industry has gradually increased, and manufacturers have reduced prices with each other, and the profit margin of non-woven bags has been squeezed. At the same time, with the hot sales of non-woven bags, the cost of non-woven bag production lines is gradually increasing, while the added value of non-woven bags of most companies is not high; the industry is facing real dilemmas such as overall profit decline.
　　 Regarding the test of non-woven bags, market professionals revealed to the author that non-woven bags can only achieve the unity of social and economic benefits through continuous improvement and a path of innovation. According to the manager of Shijiazhuang, Hebei, the non-woven bags are printed and flocked to increase the added value of their products, and at the same time, the appearance and shape of the non-woven bags are differentiated to make their color patterns. Rich, bright and lively, especially flocking non-woven bags are more solemn and elegant. It is expected that the market outlook for non-woven bags at home and abroad will still be large, and the market development prospects are good.
　　Experts pointed out that it is estimated that by 2014, the annual consumption of final nonwoven products in the world will increase to 6.3 million tons. According to data analysis from the Statistics Center of the China Textile Industry Association, as of May 2011, the total output of non-woven bags nationwide was 926,918 tons, a year-on-year increase of 25.15%. Under the influence of the country's continued implementation of environmental protection policies, environmentally friendly non-woven bags will enter a stage of rapid development in the next five years, and my country's non-woven bag industry will achieve further development.
　　  How to distinguish between toxic and non-toxic reusable bags
　　 Today is a society that promotes low-carbon and environmental protection. There are fewer and fewer non-renewable resources in nature, while the damage to the environment by human daily life is getting more and more serious. Large amounts of greenhouse gases and non-degradable garbage have become the most serious problems that bother us. In recent years, many countries have introduced some new environmental protection measures to promote the use of environmentally friendly products. Take shopping as an example. Our previous habit is to use plastic bags, which is not only convenient but also cheap. But after knowing the harm of plastic bags to the environment, the number of people using them has gradually decreased. Nowadays, paper bags, non-woven bags, eco-friendly shopping bags, etc. are more common in the market. As the number of users increases, this kind of market is becoming more and more expansive. Although all we use are eco-friendly bags, there is no shortage of high-quality and inferior ones among these eco-friendly bags. Many inferior environmental protection bags are toxic to a certain degree and cause great harm to the human body. So, how can we distinguish between toxic and non-toxic environmental bags?
　　 Method 1: Observation When we get the bag, we must first observe and judge from its color and appearance. Generally, non-toxic bags are milky white, translucent, or colorless and transparent, flexible, and feel smooth. The surface color of toxic bags is mostly turbid, light yellow, and sticky to the touch.
　　Method 2: Water immersion detection Since the non-toxic bag has a small specific gravity, when we immerse the bag in water, it can surface by itself. The toxic bag is slightly larger than the important one, and will not emerge on its own, and may still sink.
　　Method 3: Fire. Because the plastic bags we use contain polyethylene materials, when they burn normally, the flame should be blue with yellow upper end, dripping like candle tears when burning, with a paraffin smell and less smoke. The toxic plastic bag goes out immediately after leaving the fire, the flame is yellow, the bottom is green, softened and can be drawn, and it has a pungent odor.
