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

紙類一次性餐具的材質(zhì)是克重在300-350克范圍內(nèi)的漂白硫酸鹽木漿紙板為原料，經(jīng)過沖壓成型工藝制成，為防止?jié)B水或滲油，表面使用對人體無害的化學(xué)助劑。這種材質(zhì)的一次性餐具，對紙板的質(zhì)量要求較高，因而成本也較高。

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.

玉米淀粉類的一次性餐具是以玉米淀粉為主要原料，加入膳食纖維和其他可食用類助劑經(jīng)攪拌捏合而成，它采用生物復(fù)配、聚糖交聯(lián)、鈣離子螯合等技術(shù)精制而成，有致密層、內(nèi)防水層、膠網(wǎng)層和外防水層四部分構(gòu)成。目前市場上的玉米淀粉一次性餐具的玉米淀粉含量并不高，而且也較高。

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.

第三種聚苯乙烯（PS）材質(zhì)。聚苯乙烯俗稱PS，是一種被廣泛用于食品容器生產(chǎn)的材質(zhì)。比如，嬰兒用的奶瓶，一次性推入注射器等都使用了這種材質(zhì)。PS材質(zhì)具有耐酸堿，耐高溫，無味，等優(yōu)點。由于PS材質(zhì)的一次性餐具早出現(xiàn)在航空航班中，作為一次性使用的餐具供乘客使用。該餐具晶瑩剔透，猶如水晶一般的，大氣，因而被稱為“一次性航空水晶餐具”。

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".
