The hottest plastic packaging products are develop

Plastic packaging products are developing in the direction of degradability

in recent years, China's packaging plastics have exceeded 4million tons. Relevant departments predict that the demand for plastic packaging materials in China will reach 5million tons in 2005. If 30% of them are disposable plastic packaging materials and products that are difficult to collect, the waste generation will reach 1.5 million tons; The area of mulching film in China is more than 500 million mu, and the demand for seedling pots, agricultural and sideline products and fresh-keeping materials is expected to reach 1million tons; Some disposable daily necessities and medical materials are also difficult to collect or not suitable for recycling, and their demand is expected to reach 1million tons. (2) resin foaming (see Figure 2) plastic waste that is difficult to recycle will reach 35 million tons. Tensile testing machines can be roughly divided into pendulum tensile testing machines and universal tensile testing machines, which will cause increasingly serious environmental problems. If 50% of them are replaced by degradable plastics, the demand for degradable plastics will reach 1.75 million tons, so degradable plastics have great market potential in China

environmentalists point out that China consumes about 6billion fast food boxes and 5billion instant noodles bowls every year. In the future, China's packaging waste will increase at a rate of 3% - 5% per year

now, the United States, Japan, Germany and other countries are vigorously developing degradable plastics, a new environmental protection material. After being discarded, degradable plastics can be decomposed by microorganisms in the soil and turned into substances harmless to the natural environment and human body. At present, polylactic acid made of corn is mostly used as raw material. At present, China is also paying close attention to formulating policies and regulations to stop "white pollution", and the development prospect of degradable plastics industry is optimistic by insiders

according to the current situation, degradable plastics are mostly used in traditional plastic products, such as packaging products and disposable production products. In addition, the markets worth developing are all kinds of daily necessities, stationery, toys, civil engineering supplies and medical plastic products

because there are few people entering these fields at present, the market demand is large, and the added value is high. Especially at present, China has begun to vigorously implement desert control, waste experimental force, electronic detection, mountain planting and grass, urban planning, as well as various slope protection and soil consolidation projects. The use of disposable plastic products will increase greatly, which is a good opportunity for degradable plastics. Developing degradable packaging products is the future trend of China's packaging industry
