Degradable plastics determine the direction of development of packaging products

In recent years, China's packaging plastics have exceeded 4 million tons, and the demand in 2005 will reach 5 million tons, of which the demand for degradable plastics will reach 1.75 million tons.

According to the forecast of related departments, in 2005, the demand for plastics for packaging in China will reach 5 million tons. According to the disposable plastic packaging materials and products that are difficult to collect, 30% of them will be used, and the amount of waste generated will reach 1.5 million tons. In China, the area of ​​the mulch can be covered by 500 million mu. The estimated demand will reach 1 million. A part of the disposable sundry goods and medical materials is also difficult to collect or is not suitable for recycling. It is expected that the demand will reach 1 million tons. As a result, the waste of plastics that are difficult to recycle will reach 3.5 million tons, and the resulting environmental problems will become increasingly serious. If 50% of them are replaced by biodegradable plastics, the demand for biodegradable plastics will reach 1.75 million tons. Therefore, biodegradable plastics have a large market potential in the market. According to statistics, China consumes about 6 billion snack boxes each year and 5 billion instant noodle bowls. In the future, China's packaging waste will increase at an annual rate of 3% to 5%.

Nowadays, developed countries such as the United States, Japan, and Germany are vigorously developing new environmentally friendly materials, such as degradable plastics. Biodegradable plastics can be decomposed by microorganisms in the soil after being discarded and turned into substances that are harmless to the natural environment and the human body. At this stage, polylactic acid made from corn is mostly used as a raw material.

At present, China is also stepping up its efforts to formulate policies and regulations to prevent white pollution. The prospects for the development of biodegradable plastics are promising by the industry. At present, the most used biodegradable plastics are on traditional plastic products such as packaging and disposable products. The development of biodegradable packaging products is the future trend of China's packaging industry.
