What are the common types of disposable meals?

What's a good disposable dishware? There are three kinds of disposable tableware products on the market: paper, corn starch and polystyrene (PS).

The material of paper disposable tableware is made of bleached kraft wood pulp board weighing 300-350 grams. It is made by stamping process. In order to prevent water or oil seepage, chemical additives harmless to human body are used on the surface. The disposable tableware made of this material requires higher quality of cardboard and therefore higher cost.

Corn starch disposable tableware is made of corn starch as the main raw material, dietary fiber and other edible additives by stirring and kneading. It is refined by biological compounding, polysaccharide cross-linking, calcium ion chelating technology. It consists of compact layer, inner waterproof layer, rubber mesh layer and outer waterproof layer. At present, the corn starch content of disposable tableware on the market is not high, and the price is also high.

The third polystyrene (PS) material. Polystyrene, commonly known as PS, is a material widely used in the production of food containers. For example, baby bottles and disposable syringes are all made of this material. PS material has the advantages of acid and alkali resistance, high temperature resistance, non-toxicity, odorless, anti-bacterial and so on. Because the disposable tableware made of PS material first appeared in air flights, it is used as disposable tableware for passengers. The tableware is crystal clear, as noble as crystal, atmospheric, so it is called "disposable aviation crystal tableware".
