We go to the supermarket, the market, shopping malls will put a plastic bag, you can buy something very easy to carry, will reduce the weight of a lot, but the plastic bag is also very fragile, accidentally broken, But because of this lightweight and fragile guy, but it is the highlight of white pollution, how also did not understand how this thing in the earth can not be centuries. So how do we make more use of plastic bags?
First analyze the benefits of using plastic bags, plastic bags, convenient, lightweight, durable, high plasticity, waterproof and anti-bacterial, cheap, more recyclable, there are no other packaging products comparable to the United States now. The invention of plastic bags bring convenience and health to human beings. The appearance of plastic bags also reduces the waste of food. The anti-bacterial and anti-mold properties also protect human health. Plastic bags can also replace other packaging materials such as cans, paper and glass to reduce energy consumption.
Secondly plastic bags positive direction to environmental change, it is added in the production process a certain amount of additives (e.g., starch, modified starch or other cellulosic, photosensitizers, biodegradation and the like), so that the stability decreases plastic packaging , Easier to degrade in the natural environment. At present, there are 19 units in Beijing that develop or produce biodegradable plastics. Tests showed that the majority of the exposure, biodegradable plastic thin after 3 months in a general environment, weight loss, strength decreases gradually splintered.
Finally, the environmental protection of plastic bags in the material province, the least waste and save energy, easy to recycle, packaging waste does not produce secondary pollution. Therefore, the selection of environmentally friendly plastic materials should be consistent with harmless, pollution-free Recycling of the basic principles of natural environmental packaging materials, although pollution-free, but the higher commercial costs, the Earth's resources is also a serious waste of composite eco-friendly materials because of low cost, pollution-free, easy recycling and other characteristics will be Become the mainstream of the future green plastic bags.
