Since 2008, China has limited the production, sales, and use of plastic shopping bag which is thinner than 0.025 mm. Many supermarkets have a positive response.
All walks of industries have high expectations for the alternatives which replace plastic shopping bags.Among them, environmental non woven bags have greatest responses.
It is no doubt for supermarkets to promote the recycling bags. But because they can not fully grasp the professional knowledge of various industries, they are lost in the selection of substitutes. So they can not detailed explain to the end consumers. Promotion efforts will naturally be greatly reduced, and there are considerations of economic interests.
Accurate in terms of national policies is limited to plastic, rather than ban plastic. Production and sales of shopping bags 0.025MM less than the thickness, is not allowed because of its low one-time use of white pollution. If the value is high, the thickness of thick reusable plastic shopping bags is not the scope of prohibition.
Alternative products are diversified. It can be divided into: paper, thick plastic, non-woven fabrics, textile fabric (nylon / cotton) bags; rattan, metal woven basket class, and mesh bags. Above industry will be allocated to different market share due to consumer preferences different. However, non-woven bags occupy absolute advantage in the market share due to the properties of the materials.
Non-woven also has the advantages of paper, thick plastic, textile fabrics, without their drawbacks, such as: paper, low cost, light weight and good print, but easily water soluble, tension difference. Inexpensive non-woven, light weight, good printing, and can be washed, a good pull. The thick plastic-like stand, but it is easy from the crease, deformation. Non-woven shape stand, but not easy to crease, and not be deformed. Feel good, to facilitate the admission carry, seam interface is easy to collapse the yarn, not easy to wash fabric. Non-woven cloth feel good, to facilitate admission to carry, seam interface does not collapse the yarn, easy to wash. Production of non-woven fabric fiber technology, plastic thermoplastic technology, the network node of the paper process, the processing can be sewn, welding, bonding into a bag, bag-shaped bags of endless variations, colorful.
The nonwoven environmental protection is increasingly subject to the attention of the public. The environmental protection of recycle bag lies in the fact that compared to plastic bags in terms of thick cloth can be used multiple times and material degradation and degradation of the product after non-toxic and turned into dust and soil affinity. The most important thing is it biodegradable.
Nonwoven degradation via the main photodegradation. Ultraviolet sunlight and artificial light, ultraviolet radiation can destroy the non-woven raw materials (mainly materials, the chemical bonds within the polymer polypropylene PP), this process is called photodegradation process, it can cause the material to fracture, gray, color changes and physical and mechanical properties decreased. After the induction period (3-12 months under conditions of light). Materials will automatically accelerate the reaction, and irreversibility.
Practical applications it is necessary to use non-woven products, environmental protection, but also consider the processes and products prior to use storage shelf life. So there must be a basic storage environment. Storage sites are the basic requirements: no direct sunlight. Light (including artificial light) will not be too bright. The product can not bare the necessary packaging. Non-high-temperature and poorly ventilated environment.
Non-woven fabrics are extremely cheap. But they are like paper bags, there are few complimentary .Different economic allocation creates different habits. Such as the thin plastic bag, due to its free, it becomes waste. The habit of paying use is necessary to cultivate. Plastic bags are casually discarded in addition to the factor that it is easy to get, there are another reasons such as no new ideas, no creative style, normal color, general printing and so on. A product can play its useful features, decorative features and advertising features, even if it is free it will be used in multiple times.

Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
The Evolution and Impact of Abamectin and Emamectin Benzoate in Pest Control
Abamectin and its derivative, emamectin benzoate, have emerged as pivotal substances in the realm of pest control, offering a broad-spectrum efficacy against various pests while maintaining a favorable environmental profile. As the agricultural industry continues to evolve, these compounds have adapted to meet the growing challenges of pest resistance, expanding their market applications and maintaining cost-effectiveness despite rising production costs.
