Disposable corn starch tableware is mainly made of materials such as corn starch, polypropylene, PS, polystyrene, etc. It is undamaged, odorless, and odorless. It usually requires meeting the following basic conditions:

（1）正常色泽，没异味，表面平整光洁，质地均匀，无条纹、划痕，无皱折、剥离，没破裂与穿孔；

(1) Normal color, no odor, smooth and clean surface, uniform texture, no stripes, scratches, wrinkles, peels, cracks or perforations;

（3）合盖、扣盖须方便，整齐没偏离，不粘接食品；

(3) Close and buckle the lid conveniently, neatly and without deviation, and do not stick to food;

（4）保温的性能较好，90℃~100℃的油或水，60℃的环境恒温在30min后无变形、起皮、起皱，无阴渗、漏；

(4) The insulation performance is good, with oil or water at 90 ℃~100 ℃ and a constant temperature of 60 ℃ for 30 minutes, without deformation, peeling, wrinkling, and no infiltration or leakage;

（5）负重3KG，高度变化≤5%（主要针对快餐餐盒，其它类型产品可根据用户需要制定相关指标）；

(5) Carrying a weight of 3KG, with a height change of ≤ 5% (mainly for fast food boxes, other types of products can have relevant indicators formulated according to user needs);

（6）合盖方便平整，对折15次以上无断裂；

(6) Easy to close and flat, folded in half for more than 15 times without breakage;

（7）一次性玉米淀粉餐具的造型美观，拿、放方便，有适应不同需求的品种；

(7) The appearance of disposable corn starch tableware is beautiful, easy to handle and place, and there are varieties that can meet different needs;

（8）0.8m跌落水泥地面无破裂；

(8) Drop 0.8m onto the cement floor without cracking;

（9）原生材料制含水率≤7%。

(9) The moisture content of raw materials is ≤ 7%.

产品卫生、、理化指标要求任一产品均有其质量要求的标准，快餐具也不例外，了解产品质量要求对于研究开发新产品的企业相当重要。

Product hygiene, safety, and physicochemical indicators require that any product has its own quality standards, and fast food utensils are no exception. Understanding product quality requirements is crucial for enterprises researching and developing new products.

玉米淀粉是柔软的，一般的玉米淀粉材料一次性食品盒的温度是-6度到+120度，所以相当适合热的食品，可以在微波炉中加热，甚在蒸汽柜中烹饪。

Corn starch is soft, and the temperature of a typical corn starch disposable food box is -6 degrees to+120 degrees, making it quite suitable for hot food. It can be heated in a microwave or even cooked in a steam cabinet.

PS是坚硬透明的。一般用PS材料制作的一次性饭盒温度在75度左右，不适合盛热饭和热菜。而PS具有良好的低温性能，是冰淇淋的包装材料。

PS is hard and transparent. Generally, disposable lunch boxes made of PS materials have a temperature of around 75 degrees, making them unsuitable for serving hot rice and dishes. PS has good low-temperature performance and is the packaging material for ice cream.

为了降低成本，有些饭盒是用PP做的，盒盖是用PS做的，优点是盒盖是透明的，而玉米淀粉是硬的，所以可以用薄的材料来做，这样可以降低成本。但是，这种设计的消费者必须了解两种材料的区别，不要把整个一次性玉米淀粉餐具的放进微波炉。

In order to reduce costs, some lunch boxes are made of PP, and the lid is made of PS. The advantage is that the lid is transparent, while corn starch is hard, so thin materials can be used to reduce costs. However, consumers of this design must understand the differences between the two materials and not put the entire disposable corn starch tableware in the microwave.
