使用餐盒注意事项：

Precautions for using lunch box:

1.不同材质餐盒使用温度要注意。

1. Pay attention to the use temperature of different material lunch boxes.

材质为PP的餐盒使用温度较高，可以盛装热饭热菜。材质为PS的餐盒，质地较硬易破裂，在使用温度达75℃时开始变软，食物要冷却室温时再装入PS餐盒，且尽量不在微波炉中连盒一起加热食物，避免有毒有害物质的迁移。PS的低温性能很好，适用于盛装冷藏食品。

The meal box made of PP has high service temperature and can hold hot meals and dishes. The meal box made of PS is hard and easy to crack. It starts to soften when the service temperature reaches 75 ℃. The food should be put into the PS meal box when it is cooled to room temperature, and try not to heat the food together in the microwave oven to avoid the migration of toxic and harmful substances. PS has good low temperature performance and is suitable for holding refrigerated food.

2.餐盒对食物成分有要求。

油脂高、糖分高的食品不适合装入餐盒，因为油的沸点容易超过塑料耐热限度，而油、糖及塑化剂等餐盒中的化学物质都容易和餐盒发生化学反应。

Foods with high fat and sugar content are not suitable to be put into the lunch box, because the boiling point of oil is easy to exceed the heat-resistant limit of plastic, and the chemicals in the lunch box such as oil, sugar and plasticizer are easy to react with the lunch box.
