（1） Remove the lid of the lunch box when heating:

有些微波炉餐盒，比如有的盒体以5号PP制造，但盒盖却以4号PE制造，而PE是不能抵受高温。所以放入微波炉前，记得把盖子取下。

Some microwave oven lunch boxes, for example, have a body made of No. 5 PP, but a lid made of No. 4 PE, which cannot withstand high temperatures. So remember to remove the lid before putting it into the microwave oven.

（二）及时更换：

（2） Timely replacement:

餐盒的使用年限一般为3-5年，但当其出现变色、变脆、变黄的情形，应立即更换。

The service life of a lunch box is generally 3-5 years, but when it becomes discolored, brittle, or yellow, it should be replaced immediately.

（三）清洁到位：

（3） Cleaning in place:

有些餐盒，为了保持密封性，会在盖子上装上密封圈。但食物残渣渗入到密封圈里，就成为了霉菌的“福地”。

In order to maintain the tightness of some lunch boxes, a sealing ring is installed on the lid. However, food residues seep into the sealing ring and become a "blessed place" for mold.

建议每次清洗时，把密封圈及其沟槽清洗干净，晾干后，再装回盖子上。

It is recommended that the sealing ring and its groove be cleaned each time they are cleaned, dried, and then reinstalled on the cover.

（四）不盛放会加速餐盒老化的食物：

（4） Not storing food that can accelerate the aging of the lunch box:

如果一次性玉米淀粉餐具内长时间存放酒精、碳酸饮料、醋等酸性物质，容易加快老化。所以，如果您家有自制的醋泡花生、杨梅酒等，记得不要放在玉米淀粉餐具里，不妨换成玻璃器皿储存。

If acidic substances such as alcohol, carbonated beverages, and vinegar are stored in disposable corn starch tableware for a long time, it is easy to accelerate aging. Therefore, if you have homemade vinegar soaked peanuts, red bayberry wine, etc., remember not to put them in cornstarch tableware, and may as well replace them with glassware for storage.

（五）一次性塑料外卖盒不建议反复使用：

（5） Reuse of disposable plastic takeout boxes is not recommended:

现在很多外卖盒，看着质量较好，标注的也是比较好的材质，有些人就忍不住洗干净囤在家里重复使用。其实这是不对的。

Nowadays, many takeout boxes are of good quality and labeled with good materials. Some people can't help but wash them and store them for reuse at home. Actually, this is not true.

出于成本控制等原因，通常一次性餐盒没有较高的标准，其制作出来的目的，就是盛装一次、温度较高的、可能有油的食物，在这个条件下使用，是的。但如果使用次数较多，就会破坏一次性玉米淀粉餐具稳定性，其中的有害物质析出，长期下来可能会影响身体~

Due to cost control and other reasons, disposable lunch boxes generally do not have high safety standards. The purpose of their production is to contain foods that are high in temperature and may contain oil once. It is safe to use them under these conditions. However, if used frequently, it will destroy the stability of disposable corn starch tableware, and harmful substances may leach out, which may affect the body in the long run~
