Shopping bags comply with environmental standards

Currently, among the major shopping bags in the markets, plastic bags, woven bags, paper bags, cotton bags and baskets. What can really be called reusable bags for shopping?For a definition of green shopping bag, shopping bags popular chat is the stuff of raw materials in the production process does not pollute the environment, the product can be easily recycled or disposed of decomposing under natural conditions, including non-contamination of reusable bag be. Analyzed and compared, in the sense that for all kinds of shopping bags on the market today that are more environmentally friendly apparently.Plastic bags are polyolefin as the main raw materials, auxiliary materials made of other materials. According to the plastic limit as provided in the standard plastic bags, plastic bags are available in three simple plastic bags, biodegradable plastic bags, and starch-based plastic bags distributed. Of these, only degradable plastic bags are distributed to the degradation and biodegradation of two ways.Non-woven fabrics, in fact, cover, nonwoven fabric made of plastic, many have the name of the fabric is a natural material, in fact, is a misunderstanding. Typically non-woven polypropylene or polyethylene, polypropylene plastic bags used in polyethylene, which belongs to the five common types of plastic for 50 years, variations of the plastic is removed. Therefore, non-woven fabrics made of bags made of the essence, the typical species such as polypropylene raw materials, even plastic bags, environmental protection and regular plastic bags are not completely degraded.For the special nonwoven bags and scatter the same terms as strong as plastic waterproof bags, but the cost was higher than plastic bags, sometimes more. It could also be noted that the use of materials in two or more non-woven bags, recycling is more difficult than ordinary plastic bags.The strength and tightness of the paper is not good. A large amount of water-based products such as packing marine products, heavy metals are also difficult to camp. First, timber, paper resources, the forests of the world is minimal, this is the biggest waste of natural resources, followed by the construction of the paper will be plenty of water pollution. Moreover, expert analysis, paper bags in the destruction of the natural environment, energy and resources and environmental pollution caused by paper production worse than plastic bags. According to statistics from the American Chemical Society, the feedstock for the production of shopping bags, 40% lower than the recycled PET reusable bag, two pounds of plastic needed to produce more energy than one kilogram of paper production is less energy 91%, compared with paper bags, synthetic production and use of more than 70% of gas. Therefore, a paper bag the biggest waste of natural resources and environmental pollution.The strength of cotton bags, paper bags can be recycled, but the poor water resistance. The advantages of bags can be recycled cotton, but the cloth bag is dirty? Washing is the most common method, but the loss of water washing, contamination of soil phosphorus detergent just washing and disinfection of bacteria.There are baskets of two materials: one is a natural material is stick polypropylene and other plastics. In the first feedstock cultivation, and a large number of the cap from the nature of the injury. The second makes use of plastic as raw material. Environmental protection in plastic bags, and single non-woven. The main disadvantage of the car is difficult to bear.  Source:http://www.cnmhc.com
