1. Judge by the material.

檢查餐盒內(nèi)是否有雜質(zhì)，有的紙碗看起來很厚實(shí)，表面是采用食用級(jí)的材質(zhì)，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(dǎo)致食物中毒，對(duì)于不透明的餐盒，在購買時(shí)要多觀察餐盒的材質(zhì)，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(gòu)成的，大家在觀察時(shí)可以多看看產(chǎn)品有無雜質(zhì)，外表干凈也可以撕開看內(nèi)層是否為合格的食用級(jí)PP材質(zhì)，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(chǎn)生了異味，則要警惕可能有毒有害，要避免使用。有很多劣質(zhì)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(zhì)，在高溫情況下會(huì)揮發(fā)出來并向水中遷移進(jìn)入到食物當(dāng)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(biāo)志來判斷。

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

一般的正規(guī)一次性餐盒在盒子上都應(yīng)該標(biāo)注有QS標(biāo)志和編號(hào)，包括使用注意事項(xiàng)、用途、使用環(huán)境、使用溫度等內(nèi)容都會(huì)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
