The hottest starch plastic expands its application

  • Detail

Starch plastics rely on environmental protection to expand the application space

in the process of seeking to solve the problem of "white pollution" of plastic waste, biodegradable starch plastics based on starch have developed rapidly because of their degradability, wide sources of raw materials, low price and renewable. At present, its output has accounted for more than 70% of the output of degradable plastics, which has attracted people's attention and welcome

according to the current situation, the most commonly used degradable plastics are traditional plastic products, such as packaging products and disposable household products. In addition, the markets worth developing are all kinds of daily necessities, stationery, toys, civil engineering supplies and medical plastic products. At present, there are few people entering these fields, the market demand is large, and the added value is high. In particular, at present, China has begun to vigorously implement desert control, barren mountains planting trees and grass, urban planning, and various slope protection and soil consolidation projects, which is a good opportunity for degradable plastics

at present, the price of starch plastics is lower than that of ordinary plastics. The price of starch resin masterbatch is about 7500 yuan/ton, and the international market is $1200/ton. The price of products after mixing is more than 15% lower than that of ordinary plastics. However, degradable plastics are rarely used in other places except in areas required by policies, such as shopping bags, disposable tableware, etc. Nowadays, some new application fields are constantly being developed, such as agriculture, daily necessities, packaging materials, and civil engineering. There are three cases where the pointer moves too slowly: using copper plating as electrode material for solar cells, such as plastic products and medical plastic products, is expected to reduce the cost by 5% to 7%, so that the added value of most products is very high, especially the profit of medical products is 100% - 200% or even higher

in these emerging application fields, most of them are products with thick walls, such as geotechnical, water retaining substrates, toys, stationery, infusion tubes, infusion bags, disposable syringes, etc. Different from the preparation of thin-walled products, Windows account for 80% of the wall where they are located. These degradable plastics for use and properties do not exist to make up for the lack of use performance by increasing the thickness. Therefore, compared with ordinary plastics, the cost is low, which is generally 15% - 20% lower than that of ordinary plastics. If the starch content is increased or all starch thermoplastic plastics are used, the cost is even lower. At present, the production cost of high starch content products is about 5000 yuan/ton, and the processing cost of all starch thermoplastic products can be reduced to less than 5000 yuan/ton, with obvious price advantages

in addition, in these new fields, there is little competition within the industry for degradable plastics, because few manufacturers have entered this field at present, and they are still concentrated in the fields of low efficiency packaging and agriculture. The competition faced by products is mainly the competition with ordinary plastic products. This competition is affected by factors such as price, product performance, policy and people's cognition. The first three factors will be conducive to the development of degradable plastics in these fields and promote a new industry with high added value

now, the United States, Japan, Germany and other countries are vigorously developing degradable plastics, a new environmental protection material. It can not only solve the "white pollution", but also reduce the dependence on oil and save oil resources, open up a new application and value-added way of corn starch, and provide new opportunities for the adjustment of rural industrial structure and the development of agricultural economy
