In real life, plastic waste is huge and its disposal puts a lot of pressure on the sanitation department. These disposable tableware and bags for packing are made of ordinary plastic, which is not degradable under natural conditions, and incineration or landfill disposal will produce toxic and harmful substances, causing serious impact on the environment. White pollution refers to the common plastic plastic bags mainly non-natural degradable material of plastic bags. Plastic plastic bags are an item used more in our daily life, which indeed brings great convenience to people, but at the same time, the damage to human beings is also incalculable.
Degraded plastics are a broad concept of plastics that undergo a period of time and contain one or more steps that result in significant changes in the structure of the material resulting in the loss of certain properties (such as integrity molecular mass structure or mechanical strength) and/or fragmentation under defined environmental conditions. Among them, the photodegradable plastic thermal oxygen degradable plastic belongs to the type plastic and should not be attributed to the biodegradable plastic.
Biodegradable plastic bags raw materials are generally PBAT + PLA (polyethylene terephthalate + polylactic acid) is the main, or mixed with starch and other biodegradable agents made of bags, also known as fully biodegradable bags. This biodegradable plastic bag is mainly degraded by the action of microorganisms. Fully biodegradable plastic bags, compostable, fully degradable in 180 days, environmentally friendly and harmless. Another biodegradable plastic bags are mainly polyethylene plastic, mixed with photodegradable agents and calcium carbonate and other mineral powders made of bags, also called photodegradable bags.
Fully degradable undershirt bag is a fully biodegradable packaging bag, widely used in wine and beverage packaging food packaging daily necessities packaging, etc., under the action of ultraviolet light can be self-photosynthetic degradation, the degraded material for inorganic powder, nature will not produce harmful substances, green health and environmental protection.
Green city construction, build a green mode of production, consumption and lifestyle, promote green development, circular development, low-carbon development, strengthen the protection of the environment and ecological maintenance, environmental protection packaging bags, the rise of packaging products will certainly drive the transformation and upgrading of packaging materials enterprises, the production of a series of biodegradable plastic bags, full biodegradable plastic bags, will contribute to the development of society out of the arm's length.
