In recent years, people's awareness of environmental protection is getting higher and higher, advocate environmental pollution, plastic bags, there is completely pollution-free plastic bags?
In general, there is no completely environmentally friendly plastic bags, the so-called environmental protection, can only be some plastic bags to add some ingredients, easy to degrade some, that is, biodegradable plastic. In the production of plastic packaging products by adding a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizer, biodegradable agent, etc.), so that the stability of plastic packaging decreased, easier to degradation in the natural environment The
Most of the degradable plastics in the general environment exposed after 3 months began to thin, weight loss, strength decreased, and gradually split into pieces. If the debris is buried in the garbage or soil, the degradation effect is not obvious.
There are four shortcomings: the use of biodegradable plastic products can not completely eliminate the "visual pollution"; third is due to technical reasons, the use of biodegradable plastic products can not completely solve the environmental "Potential harm"; Fourth, the degradation of plastic due to contain special additives and difficult to recycling.
In fact, environmental protection, is less use, the rational use of plastic bags or a fixed plastic bags to use, reduce the amount, but also through the government recycling, in order to reduce environmental pollution.
