The development of corn starch disposable tableware

 The disposable tableware produced by Hengfeng corn starch tableware manufacturer uses corn cob powder, chitosan, starch, polyvinyl alcohol, xanthan gum, and water as raw materials. The optimal ratio of each raw material is confirmed through orthogonal experiments, and then different The extruding method can be used to make it into disposable cornstarch tableware such as tableware, chopsticks, lunch box and so on. Regarding the development of corn starch technology, the following is a detailed introduction.

 

The significance of the development of corn starch plastic tableware is not only embodied in the environmental aspect. The use of corn and other plants as raw materials has solved the dilemma that chemical plastics are derived from petroleum and the raw materials are easily depleted from the source. Using plants as raw materials, the final decomposition products can still return to nature and will not harm the surrounding environment. The process of production, use, and decomposition constitutes a closed loop. With the development of the "corn plastic tableware" industry, the added value of corn and other crops will also increase accordingly, which is beneficial to increase farmers' income.

 

Corncob flour is suitable for various processing methods such as blow molding and thermoplastics. It is easy to process and has a wide range of applications. PLA itself is an aliphatic polyester, with the basic characteristics of general polymer materials, and can be used in packaging materials, home appliance housings or as a degradable fiber material. PLA can replace part of the application of polyethylene and polypropylene and is widely used in various molding processes of plastics.

 

For example: plastic containers, cups, plates, food containers (boxes), liquid containers (bottles, barrels), disposable tableware (knives, spoons, forks, packaging film, plastic bags, foamed plastics (containers, packaging materials), mulch, Textiles (clothing, non-woven fabrics), etc. PLA material has good transparency and gloss, which is beneficial to display the characteristics of the packaged goods, good gas and water resistance, convenient printing, and its excellent performance determines that it will occupy an important position in the packaging market position.

 

With the advancement of production technology and the improvement of technology, disposable tableware will be industrialized on a large scale. After a few years, the "white pollution" that plagues people will become history. This should be a major development in the environmental protection material industry.
