From the perspective of color, qualified products have uniform color and relatively fine texture; Unqualified products have dark colors, uneven coloring, and some add fluorescent substances, resulting in a less natural appearance of white.

從味道上看，合格產品基本沒有太多味道；而劣質產品基本都有較大的異味。

From the perspective of taste, qualified products do not have much taste; Poor quality products generally have significant odors.

從手感上看，合格產品較為柔軟，用手揉捏不易碎；不合格產品表面較為粗糙，柔韌性差，用手反復對折產品容易碎裂。

From the perspective of hand feel, qualified products are relatively soft and not fragile when kneaded by hand; The surface of unqualified products is relatively rough, with poor flexibility, and the product is prone to fragmentation when repeatedly folded by hand.

材質為PS的餐盒，質地較硬易破裂，適用于盛裝冷藏食品，不適宜在微波爐中連盒一起加熱食物。材質為PP的餐盒具有良好耐熱性，熔點在170攝氏度左右，可以放入微波爐中加熱。

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，有些商家為了節約成本，餐盒的蓋子部分會使用不同材料，所以建議再確認一下蓋子上是否有PP標志。

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.

不同材質塑料的耐受溫度和忌用條件，注意不同的食物成分對餐盒有要求。

The temperature tolerance and avoidance conditions of different materials of plastic should be noted, and different food ingredients have requirements for the lunch box.

高油脂、高糖分的食品不適合裝入塑料餐盒。

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

因為油的沸點容易超過塑料耐熱極限，食品中的油、糖及餐盒中的塑化劑等化學物質容易發生化學反應，使得有毒物質發生遷移，造成人體損傷。

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.
