一次性泡沫塑料餐具

Disposable foamed plastic tableware

主要成分是聚丙烯。因其具有保温、耐压、价格便宜等优点而被广泛使用，但由于存在白色污染问题，国家于1995年禁止使用。使用一次性泡沫塑料餐具，但禁令于2013年解除。一次性泡沫外卖餐具的很大危害之一是当食物温度超过65度时，会释放出双酚A等有毒物质，渗入食物中，并蓄积。在丙烯的合成过程中，如果聚合不充分，会引起二聚体和三聚体的溶解，对肝脏和肾脏造成损害。

The main component is polypropylene. It is widely used because of its advantages such as heat preservation, pressure resistance and low price. However, due to the problem of white pollution, it was banned by the state in 1995. Disposable foamed plastic tableware was used, but the ban was lifted in 2013. One of the great hazards of disposable foam take away tableware is that when the food temperature exceeds 65 ℃, toxic substances such as bisphenol A will be released, infiltrated into the food and accumulated. In the process of propylene synthesis, if the polymerization is not sufficient, it will cause the dissolution of dimer and trimer, causing damage to the liver and kidney.

PP塑料餐具

PP plastic tableware

也就是说，由聚丙烯制成的餐具。因为聚丙烯更耐高温，所以它的很高温度在150度左右，因为它足以盛放一般的食物。要求聚丙烯餐具透明、坚固、无毒无害。常用的卡扣盒就是用这种材料制成的，也出现在一次性快餐盒上。

That is, tableware made of polypropylene. Because polypropylene is more resistant to high temperature, its very high temperature is about 150 degrees, because it is enough to hold ordinary food. Polypropylene tableware shall be transparent, solid, non-toxic and harmless. The commonly used snap box is made of this material and also appears on the disposable fast food box.

纸餐具

Paper tableware

它的原料多为木浆，然后用冲压工具压制成型，然后在表面涂上化学添加剂，防止渗水。纸餐具也是无毒无害的。是的，在一些高档的外卖店里，他们通常使用这种餐具来包装食物，看起来很精致。当然也有便宜的餐具，比如有时用来盛酸的麻辣面、牛肉面等餐具。

Its raw material is mostly wood pulp, which is then pressed with stamping tools, and then coated with chemical additives on the surface to prevent water seepage. Paper tableware is also non-toxic and harmless. Yes, in some high-end take away stores, they usually use this kind of tableware to pack food. It looks very delicate. Of course, there are also cheap tableware, such as spicy noodles and beef noodles, which are sometimes used to hold acid.

可降解餐具

Biodegradable Cutlery 

它也主要由塑料组成，但会添加光敏剂或淀粉。这种外卖餐具在自然环境中微生物酶的作用下分解成二氧化碳和水。对环境无有害影响。

It is also mainly composed of plastic, but photosensitizer or starch will be added. This take away tableware is decomposed into carbon dioxide and water under the action of microbial enzymes in the natural environment. No harmful impact on the environment.

哪些外卖盒不能用

Which take out boxes do not work

1.避免使用没有身份证的塑料制品。所谓“身份证”，是指塑料制品底部的三角形标记。1、5和6是主要的。一般来说，它们是相对安全的。1号和6号快餐盒耐热性比较差，不能加热，不能装高温食品。5号零食盒可以耐200℃左右的高温，可放入微波炉加热，反复加热也不成问题。

1. avoid using plastic products without ID cards. The so-called "ID card" refers to the triangle mark at the bottom of plastic products. 1. 5 and 6 are primary. Generally speaking, they are relatively safe. No. 1 and No. 6 fast food boxes have poor heat resistance. They cannot be heated and cannot contain high-temperature food. The No. 5 snack box can withstand a high temperature of about 200 ℃ and can be heated in a microwave oven. Repeated heating is not a problem.

2、没有QS标识和编号，饭盒表面不光滑，有杂质或斑点。

2. Without QS identification and number, the surface of the lunch box is not smooth, with impurities or spots.

3、一般来说，透明的一次性外卖打包盒是用纯聚丙烯（PP）生产的，安全系数比较高；可以使用颜色鲜艳的饭盒。废塑料，所以颜色越深越不安全。

3. Generally speaking, the transparent disposable take away packaging box is made of pure polypropylene (PP), with a high safety factor; You can use brightly colored lunch boxes. Waste plastic, so the darker the color, the less safe.
