What are the damages of plastic bags: Plastic bags bring convenience to people's lives, but temporary convenience brings long-term damage.

The recycling value of plastic bags is low. In the process of using plastic bags, they are not only distributed in city streets, tourist areas, water bodies, but also cause visual pollution on both sides of roads and railways, and there is also potential damage. The plastic structure is stable, not easily degraded by natural microorganisms, and does not separate for a long time in the natural environment. This means that if the waste plastic waste is not recycled, it will become a pollutant in the environment for a long time and will continue to accumulate, which will cause great damage to the environment.
According to statistics, the world uses 260 million tons of plastic every year, of which 170 million tons are disposable.
store fruit
Vegetables and fruits are stored in plastic bags, a scientific way to keep them fresh in winter. The principle is to reduce the oxygen concentration and add carbon dioxide concentration to make the fruits and vegetables in a dormant state and extend the storage period. However, the storage time should not be too long.
Since vegetables and fruits are organic foods, they contain high water content (60~95%), water-soluble nutrients and enzymes. Continue vigorous respiratory activity throughout storage. Generally speaking, for every 10°C, the respiration intensity is doubled. Under aerobic conditions, sugars or other organic substances in fruits and vegetables are oxidized and differentiated, carbon dioxide and water are generated, and a lot of ripeness is released. In the absence of oxygen, sugar does not oxidize, but instead breaks down to produce alcohol, carbon dioxide, and a small amount of heat.
However, the concentration of carbon dioxide cannot be added indefinitely, only 10% is added, and the oxygen concentration cannot be reduced beyond 5%. Otherwise, in order to obtain sufficient energy for life activities during hypoxia, it is necessary to differentiate more nutrients. At the same time, because the alcohol produced by hypoxic respiration remains in the fruit, it will cause the fruit to rot and deteriorate, so the fruit and vegetables should not be stored in plastic bags for a long time.
To put fruits and vegetables in plastic bags, you can open the plastic bags for 2 to 3 days, give carbon dioxide and heat, and then coat the mouth, which can reduce the occurrence of rot and deterioration.
Agricultural influence
The accumulation of waste plastic products in the soil will affect the absorption of nutrients and water by crops, resulting in crop loss.
animal threat
Plastic products discarded on land or in water are eaten by animals, causing them to die. 20 herders near Qinghai Lake killed nearly 1,000 sheep, resulting in economic losses of more than 300,000 yuan. Sheep like to eat oily residues that contain plastic bags, but they often eat plastic bags together. Because the plastic they eat sticks to their stomachs for so long and is hard to digest, the sheep's stomachs are so full of food they can't eat any more. Then, they could only starve to death. This condition is common in zoos, pastoral areas, rural areas and the ocean.
The inability of plastic to degrade naturally leads to many animal tragedies. For example, mountain males, pelicans, dolphins and other animals in the zoo will swallow the number by mistake. 1 plastic bottle lost by tourist then died of pain from indigestion. Looking at the beautiful and pure sea, close at hand, in fact, there are all kinds of plastic garbage floating in the sea that cannot hold the sea water. I took samples from the intestines of many dead sea birds and found that all kinds of plastics could not be digested.
Therefore, Dongguan Bite Packaging has developed a new type of degradable packaging bag. Generally, paper packaging bags are combined with degradable materials such as PLA to achieve full biodegradable packaging and photo-oxygen degradable packaging bags. Please contact us if necessary.
