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

有些微波爐餐盒，比如有的盒體以5號PP制造，但盒蓋卻以4號PE制造，而PE是不能抵受高溫。所以放入微波爐前，記得把蓋子取下。

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）及時更換：

（2） Timely replacement:

餐盒的使用年限一般為3-5年，但當其出現變色、變脆、變黃的情形，應立即更換。

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）清潔到位：

（3） Cleaning in place:

有些餐盒，為了保持密封性，會在蓋子上裝上密封圈。但食物殘渣滲入到密封圈里，就成為了霉菌的“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.

建議每次清洗時，把密封圈及其溝槽清洗干凈，晾干后，再裝回蓋子上。

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）不盛放會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內長時間存放酒精、碳酸飲料、醋等酸性物質，容易加快老化。所以，如果您家有自制的醋泡花生、楊梅酒等，記得不要放在玉米淀粉餐具里，不妨換成玻璃器皿儲存。

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）一次性塑料外賣盒不建議反復使用：

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

現在很多外賣盒，看著質量較好，標注的也是比較好的材質，有些人就忍不住洗干凈囤在家里重復使用。其實這是不對的。

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，通常一次性餐盒沒有較高的標準，其制作出來的目的，就是盛裝一次、溫度較高的、可能有油的食物，在這個條件下使用，是的。但如果使用次數較多，就會破壞一次性玉米淀粉餐具穩定性，其中的有害物質析出，長期下來可能會影響身體~

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~
