Plastic bags are common plastic packaging products, which are widely used in plastic packaging products. Today, let's take a look at its classification. There are three common classifications: general-purpose plastic bags, PE plastic bags, and degradable plastic bags.
 
First, general-purpose plastic bags have both the function of shopping bags and garbage bags. The common ones are portable plastic bags and garbage plastic bags. Portable plastic bags are actually a type of PE plastic bags. Portable plastic bags are generally disposable shopping bags common in the market. Plastic bag manufacturers generally print plastic bags with smiley faces for use in wholesale markets. Such plastic bags usually do not have a fixed design scheme. , General-purpose plastic bags in the takeaway packaging market. Common places of use are: bags for vegetable markets, bags for fruit shops, bags for households, bags for bookstores and bags for clothing.
 
 
Second, degradable plastic bags include: fully biodegradable plastic bags, photodegradable plastic bags, oxidative/biodegradable plastic bags, thermoplastic starch resin degradation plastic bags.
 
Fully biodegradable plastic bags are the most common and can be directly degraded in nature. Polylactic acid is mainly made of corn as raw material, and after degradation, it completely becomes a biodegradable material of carbon dioxide and water, which is a real degradable plastic. Bags, which can be said to be an alternative to plastic bags, can fundamentally solve the problem of plastic bag pollution, rather than cure the symptoms.
 
Degradable plastic bags are a new type of environmentally friendly plastic bags, which are also produced according to the specifications and standards required by the current state. The main types are: PLA: polylactic acid, which is a polymer obtained by polymerizing lactic acid as the main raw material. It is a new type of bio-based and renewable biodegradable plastic bag material. It has good solvent resistance, biocompatibility, gloss, transparency, as well as certain bacteria resistance, flame retardancy and UV resistance. PBAT: A copolymer of butylene adipate and butylene terephthalate, which is a thermoplastic biodegradable plastic. It not only has good ductility and elongation at break, but also has good impact resistance; in addition, it has excellent biodegradability and is one of the most active degradable plastic materials in the research of biodegradable plastic bag materials.
 
 
Third, environmentally friendly plastic bags include: PLA plastic bags, PHAs plastic bags, PBA plastic bags, PBS plastic bags, etc.
 
Environmentally friendly plastic bags are the abbreviations of various types of biodegradable plastic bags. With the development of science and technology, various materials that can replace traditional PE plastics have appeared, including PLA, PHAs, PBA, PBS and other polymer materials. Can replace traditional PE plastic bags. Environmentally friendly plastic bags have been widely used at present: supermarket shopping bags, continuous fresh-keeping bags, plastic films, etc. have large-scale application examples in China.
