使用餐盒注意事項：

Precautions for using lunch box:

1.不同材質餐盒使用溫度要注意。

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

材質為PP的餐盒使用溫度較高，可以盛裝熱飯熱菜。材質為PS的餐盒，質地較硬易破裂，在使用溫度達75℃時開始變軟，食物要冷卻室溫時再裝入PS餐盒，且盡量不在微波爐中連盒一起加熱食物，避免有毒有害物質的遷移。PS的低溫性能很好，適用于盛裝冷藏食品。

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.餐盒對食物成分有要求。

2. The lunch box has requirements for food composition.

油脂高、糖分高的食品不適合裝入餐盒，因為油的沸點容易超過塑料耐熱限度，而油、糖及塑化劑等餐盒中的化學物質都容易和餐盒發生化學反應。

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.
