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. The cost of non-woven bag production lines is gradually increasing, but the added value of most companies' non-woven bags 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. 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 the 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 non-woven products worldwide 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 environmental bags
Today is a society that advocates low-carbon and environmental protection. There are fewer and fewer non-renewable resources in the natural world, while the damage to the environment by human daily life is getting more and more serious. A large amount of greenhouse gases and non-degradable garbage have become serious problems that plague 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 was 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 broad. Although all we use are eco-friendly bags, there is no shortage of good and inferior ones among these eco-friendly bags. Many inferior environmental protection bags have certain toxicity and are harmful 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 of toxic bags is mostly turbid, pale 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 by itself, and may still sink.
Method Three: Burning As the plastic bags we use contain polyethylene materials, during normal burning, 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, softens and can be drawn, and has a pungent smell.
