1. Judge by the material.

檢查餐盒內是否有雜質，有的紙碗看起來很厚實，表面是采用食用級的材質，而中間卻采用一些回料紙，而如果不檢查出來而誤用則很可能導致食物中毒，對于不透明的餐盒，在購買時要多觀察餐盒的材質，如果可以撕開則撕開查看。

Check whether there are impurities in the lunch box. Some paper bowls look very thick. The surface is made of food grade material, but some recycled paper is used in the middle. If they are not checked and misused, it is likely to lead to food poisoning. For opaque lunch boxes, observe the material of the lunch box when buying. If they can be torn, tear them up and check.

這些餐盒一般都是由多層構成的，大家在觀察時可以多看看產品有無雜質，外表干凈也可以撕開看內層是否為合格的食用級PP材質，這樣可以更加放心。

These lunch boxes are generally composed of multiple layers. When observing, you can see whether the product has impurities, the appearance is clean, or you can tear it open to see whether the inner layer is qualified edible PP material, so you can be more assured.

2、通過聞味道來判斷

2. Judge by smell

如果餐盒在倒入熱水后產生了異味，則要警惕可能有毒有害，要避免使用。有很多劣質餐盒都有刺鼻的刺激性氣味，而這很可能其中含有有害物質，在高溫情況下會揮發出來并向水中遷移進入到食物當中，從而危害到人體健康。所以大家要選擇沒有異味的一次性餐盒。

If the lunch box has peculiar smell after pouring hot water, be alert to possible toxicity and avoid use. Many inferior lunch boxes have pungent and pungent smell, which is likely to contain harmful substances, which will volatilize and migrate into the water under high temperature, thus endangering human health. So we should choose a disposable lunch box without peculiar smell.

3、通過看餐盒上的標志來判斷。

3. Judge by looking at the sign on the lunch box.

一般的正規一次性餐盒在盒子上都應該標注有QS標志和編號，包括使用注意事項、用途、使用環境、使用溫度等內容都會有說明

General regular disposable lunch boxes should be marked with QS mark and number on the box, including instructions for use precautions, purpose, use environment, use temperature, etc
