Description

Full-biodegradable easily-torn conjoined medical bag

Technical Field

The utility model relates to the technical field of packaging bags, in particular to a full-biodegradable easy-tearing opening conjoined medical bag.

Background

The annual output of plastics in China is 3000 ten thousand tons, and the consumption is more than 6000 ten thousand tons. The annual output of plastics worldwide is 10 hundred million tons, if the annual plastic waste amount of China is calculated according to 15% of the plastic waste amount per year, the annual plastic waste amount of China is more than 1000 million tons, and the proportion of the waste plastics in the garbage accounts for 40%, so that a large amount of waste plastics are buried underground as garbage, and undoubtedly, greater pressure is brought to the originally-lacked arable land. The plastic brings convenience to the life of people and brings difficult-to-collect aftertroubles to the environment, and the disaster of the plastic to the environment is called as 'white pollution'. The medicine bag does bring convenience to the life of people, but the convenience brings long-term harm. Generally, the harm of non-degradable mass plastics to the earth includes: 1. the plastic has lower recycling value, is easy to scatter in urban streets and tourist areas in the using process, has stable structure, is not easy to be degraded by natural microorganism bacteria, and is not separated in the natural environment for a long time. This means that waste plastics, if not recycled, will become a pollutant in the environment and will be permanently present and accumulate, causing a significant environmental hazard. 2. Affecting the agricultural development. Waste plastic products are mixed in soil and continuously accumulated, and can influence crops to absorb nutrients and moisture. 3. Waste plastic products discarded on land or in water are swallowed by animals as food, resulting in death of the animals. 4. Along with the landfill, not only can a large amount of land be occupied, but also the occupied land can not be recovered for a long time, and the sustainable utilization of the land is influenced. If the medical bags entering the household garbage are buried, the medical bags are not degraded within 200 years.

Aiming at the problem, the inventor provides a full-biodegradable medical bag, but the side end of the medical bag is not provided with an easy-to-tear line which is convenient for a user to tear, so that the medical bag is inconvenient for the user to use.
