从颜色上看，合格的产品颜色均匀，质地相对细腻；不合格的产品颜色较深，着色不均匀，有些还添加了荧光物质，导致白色的外观不太自然。

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.从口味道的角度来说，合格的产品没有太多的味道；劣质产品通常有明显的气味。

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

3.从手感上看，合格的产品用手揉捏时相对柔软，不易碎；不合格产品的表面比较粗糙，柔韧性较差，用手反复折叠容易碎裂。

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材料制成的食品盒坚硬且容易破裂，因此适合存放冷藏食品。把食物放在微波炉里一起加热是不合适的。PP制成的食品盒具有良好的耐热性，熔点约为170摄氏度4.，可以在微波炉中加热。

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，为了节省成本，一些企业可能会使用不同的材料制作餐盒盖。因此，建议再次确认盖子上是否有PP标志。

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.应注意不同材料的塑料的温度耐受和避免条件，不同的食品成分对餐盒有要求。

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适合用塑料一次性餐盒包装。

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

8.由于油的沸点往往超过塑料的耐火上限，食物中的油、糖和饭盒中的增塑剂等化学物质容易发生化学反应，导致有毒物质迁移，造成人体伤害。

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.

如何实现一次性餐具的质量？

How to achieve the quality and safety of disposable tableware?

1.卫生清洁：产品透明度高，质地晶莹剔透。产品的质量可以通过肉眼直接观察杂质、污渍、指纹和划痕以及二次使用来确定。它是干净可见的。

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产品，不重复使用，可以防止循环使用的交叉感染，从而很好地保护自己。

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级PS材料，耐酸、耐碱、耐高温；无菌和性能等特点。

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.按照标准生产：采用精度高的自动化设备，高温一次性注塑，紫外线，自动流水线无菌包装；完全实现从生产到包装的无菌无尘操作。

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.快速消费品：具有消费周期短、补充消费大、产品服务周期短、市场大的特点；

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

6.废弃物回收：将废旧一次性餐盒回收用于工业原料，造粒销售，增加双向收益，变废为宝。

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