With the rapid development of the global economy and the emphasis on the environment, countries have issued policy documents to limit and ban the production and use of plastics. Vigorously promote the use of degradable disposable tableware, environmentally friendly tableware and environmentally friendly packaging materials. With the improvement of people’s living standards and changes in consumption awareness, more and more people are using and discarding disposable tableware and packaging products almost every day, and the quantity is staggering. The consumption market of environmentally friendly disposable tableware is growing at a rate of 10% every year. The promotion and utilization of new degradable materials has broad prospects for market development.
Starch disposable tableware is a natural polymer material and a completely biodegradable tableware. Its unique bonding properties and natural biodegradable tableware properties are characteristics that other chemical synthetic materials cannot achieve. The main raw materials for compostable and environmentally friendly tableware can be It is corn starch, tapioca starch, and other vegetable starches. Especially for corn starch, countries have a large number of planting resources and deep processing starch factories. Degradable disposable tableware and compostable packaging material products have no three types of waste discharge (waste water, waste gas, waste residue, noise) during the entire production process, and corn starch tableware products that do not pollute the environment. Under the action of microbial (bacteria, mold, algae) enzymes in the natural environment, corn starch tableware can catalyze compostable starch tableware and compostable packaging materials after use and discard, and the biodegradation of disposable tableware leads to moldy appearance and internal quality of starch tableware. Variation, can be eaten by insects. The biodegradation rate is almost 100%. Under proper temperature and environment, degradable starch tableware can be degraded to form carbon dioxide and water within 30 days. Compostable degradable tableware does not pollute the soil and air, increases soil nutrients, and returns to nature.
Compostable starch tableware belongs to pollution-free and green packaging materials. Degradable starch disposable tableware is synthesized by corn starch and auxiliary natural plant materials, Degradable disposable cups do not contain harmful substances to human body, and can realize rapid biodegradation and zero pollution: degradable disposable plate products are buried in soil, which can degrade to form carbon dioxide and water after 30 days, and degradable disposable trays do not pollute soil and air. Save resources: The raw material of corn starch tableware comes from plants growing in nature, which is an inexhaustible renewable resource of natural materials. Disposable plastic tableware is the main product in circulation in the market now, including paper tableware and plastic tableware, which need to consume a lot of wood fiber and petrochemical energy in production. Foamed plastic disposable plastic products are difficult to be degraded in nature, because disposable plastics are all synthetic. Biodegradable compostable disposable cups can save a lot of oil and forest resources in production.
