At present, there are many kinds of plastic products. Plastics are also widely used in life, ranging from a straw to a car. In recent years, with the continuous improvement of China's recycling system of renewable resources, most plastic products with long consumption cycle can be basically recycled. Some plastic products with short consumption cycle, such as beverage bottles, plastic pots and plastic toys, can be recycled effectively. However, at the same time, the low reuse value or some varieties that are difficult to be classified and utilized have become the main source of plastic pollution, which is also the key to the control of plastic pollution.
In December 2017, the United Nations adopted a resolution aimed at stopping the dumping of plastic shopping bags, which was supported by more than 200 countries. Governments all recognized the need to clean up large amounts of plastic waste in the ocean and reduce the amount of plastic products entering the consumption system. So, what's the difference between woven fabric bags made of plastic and nonwoven shopping bags?
Woven grocery bag, also known as snakeskin bag, is a kind of plastic bag. Its raw materials are generally polyethylene, polypropylene and other chemical plastic raw materials. Polyethylene is a kind of thermoplastic resin prepared by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α - olefins. Polyethylene is odorless and nontoxic. It has excellent low temperature resistance and good chemical stability. In addition, it is resistant to most acid and alkali attack (not resistant to oxidizing acid). It is insoluble in common solvents at room temperature and has excellent electrical insulation.
Nonwoven box bag is made of non-woven fabric. It is a kind of new environmental protection material. It has the characteristics of moisture-proof, air permeability, flexibility and light weight.
Scope of application
Due to the problems of product resources and price, 6 billion woven cloth bags are used in cement packaging every year in China, accounting for more than 85% of bulk cement packaging. With the development and application of flexible container bags, plastic woven polypropylene bags with handles are widely used in marine, transportation, industrial and agricultural products. In agricultural products packaging, plastic woven reusable bags have been widely used in aquatic products packaging, poultry feed packaging, covering materials of farms.
Due to its environmental protection characteristics, nonwoven cotton bags are widely used, especially in industrial production, agriculture and animal husbandry, which have made a lot of contributions to the society.
In addition, nonwoven sling bag also has a wide range of applications in the manufacturing industry of transportation, especially in the packaging of concentrate feed and aquatic products. And in the level of crop planting, it also has raw materials that can resist wind and shade. Naturally, non-woven environmental bags are also used in food enterprises. In fact, in the manufacturing industry of transporting holiday tourism, non-woven bags are often used, such as travel bags and sun umbrellas.
The application scope of non-woven bags is very wide. And with the development of society and the improvement of technology, this bag will have a wider range of utilization.
