從顏色上看，合格的產品顏色均勻，質地相對細膩；不合格的產品顏色較深，著色不均勻，有些還添加了熒光物質，導致白色的外觀不太自然。

From a color perspective, qualified products have uniform colors and relatively delicate textures; Unqualified products have darker colors, uneven coloring, and some even add fluorescent substances, resulting in an unnatural white appearance.

2.從口味道的角度來說，合格的產品沒有太多的味道；劣質產品通常有明顯的氣味。

From the perspective of taste, qualified products do not have too much flavor; Poor quality products usually have a noticeable odor.

3.從手感上看，合格的產品用手揉捏時相對柔軟，不易碎；不合格產品的表面比較粗糙，柔韌性較差，用手反復折疊容易碎裂。

3. From the perspective of hand feel, qualified products are relatively soft and not easily broken when kneaded by hand; The surface of unqualified products is relatively rough, with poor flexibility, and it is easy to break when folded repeatedly by hand.

由PS材料制成的食品盒堅硬且容易破裂，因此適合存放冷藏食品。把食物放在微波爐里一起加熱是不合適的。PP制成的食品盒具有良好的耐熱性，熔點約為170攝氏度4.，可以在微波爐中加熱。

Food boxes made of PS material are hard and prone to breakage, making them suitable for storing refrigerated food. It is not appropriate to heat food together in the microwave. The food box made of PP has good heat resistance, with a melting point of about 170 degrees Celsius. It can be heated in a microwave.

5.然而，值得注意的是，為了節省成本，一些企業可能會使用不同的材料制作餐盒蓋。因此，建議再次確認蓋子上是否有PP標志。

However, it is worth noting that in order to save costs, some companies may use different materials to make meal box covers. Therefore, it is recommended to confirm again whether there is a PP mark on the lid.

6.應注意不同材料的塑料的溫度耐受和避免條件，不同的食品成分對餐盒有要求。

6. Attention should be paid to the temperature tolerance and avoidance conditions of plastics made of different materials, and different food ingredients have requirements for meal boxes.

7.脂肪和糖分含量高的食物不適合用塑料一次性餐盒包裝。

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

8.由于油的沸點往往超過塑料的耐火上限，食物中的油、糖和飯盒中的增塑劑等化學物質容易發生化學反應，導致有毒物質遷移，造成人體傷害。

8. Due to the fact that the boiling point of oil often exceeds the fire resistance limit of plastics, chemical substances such as oil, sugar, and plasticizers in food are prone to chemical reactions, leading to the migration of toxic substances and causing harm to the human body.

如何實現一次性餐具的質量？

How to achieve the quality and safety of disposable tableware?

1.衛生清潔：產品透明度高，質地晶瑩剔透。產品的質量可以通過肉眼直接觀察雜質、污漬、指紋和劃痕以及二次使用來確定。它是干凈可見的。

1. Hygiene and cleaning: The product has high transparency and a crystal clear texture. The quality of the product can be determined by direct observation of impurities, stains, fingerprints and scratches with the naked eye, as well as secondary use. It is clean and visible.

2.一次性使用：一次性水晶餐具是一次性產品，不重復使用，可以防止循環使用的交叉感染，從而很好地保護自己。

2. Disposable: Disposable crystal tableware is a disposable product that is not reused and can prevent cross infection from repeated use, thus protecting oneself well.

3.：一次性航空水晶餐具采用食品級PS材料，耐酸、耐堿、耐高溫；無菌和性能等特點。

3. Safety: Disposable aviation crystal tableware is made of food grade PS material, which is acid resistant, alkali resistant, and high-temperature resistant; Characteristics such as sterility and antibacterial properties.

4.按照標準生產：采用精度高的自動化設備，高溫一次性注塑，紫外線，自動流水線無菌包裝；完全實現從生產到包裝的無菌無塵操作。

4. Production according to standards: using high-precision automated equipment, high-temperature one-time injection molding, UV disinfection, automatic assembly line sterile packaging; Fully achieve sterile and dust-free operation from production to packaging.

5.快速消費品：具有消費周期短、補充消費大、產品服務周期短、市場大的特點；

5. Fast moving consumer goods: characterized by short consumption cycles, large supplementary consumption, short product and service cycles, and a large market;

6.廢棄物回收：將廢舊一次性餐盒回收用于工業原料，造粒銷售，增加雙向收益，變廢為寶。

6. Waste recycling: Recycling discarded disposable lunch boxes for industrial raw materials, granulation sales, increasing two-way revenue, and turning waste into treasure.
