材质为PS的餐盒，质地较硬易破裂，适用于盛装冷藏食品，不适宜在微波炉中连盒一起加热食物。材质为PP的餐盒具有良好耐热性，熔点在170摄氏度左右，可以放入微波炉中加热。

The food box made of PS material is hard and prone to cracking, making it suitable for holding refrigerated food. It is not suitable to heat food together in a microwave oven. The food box made of PP has good heat resistance, with a melting point of around 170 degrees Celsius, and can be heated in a microwave oven.

但值得注意的是，有些商家为了节约成本，餐盒的盖子部分会使用不同材料，所以建议再确认一下盖子上是否有PP标志。

However, it is worth noting that some businesses may use different materials for the lid of their lunch boxes in order to save costs. Therefore, it is recommended to confirm again whether there is a PP logo on the lid.

不同材质塑料的耐受温度和忌用条件，注意不同的食物成分对餐盒有要求。

高油脂、高糖分的食品不适合装入塑料餐盒。

Foods with high fat and sugar content are not suitable for packaging in plastic lunch boxes.

因为油的沸点容易超过塑料耐热极限，食品中的油、糖及餐盒中的塑化剂等化学物质容易发生化学反应，使得有毒物质发生迁移，造成人体损伤。

Because the boiling point of oil easily exceeds the heat resistance limit of plastic, chemical substances such as oil, sugar, and plasticizers in food are prone to chemical reactions, causing toxic substances to migrate and causing human damage.
