In this era of fast food, disposable lunch box is closely related to our life, so safety and environmental protection is particularly important. More and more customers and consumers are paying attention to the definition standard between standard lunch box and inferior lunch box, especially when they purchase.

一次性餐盒其材质分类繁多，不同材质的产品其生产工艺也有很大不同，我们如何才能进行辨别他们的区别的呢：

There are many kinds of disposable lunch boxes, and the production processes of different materials are also very different. How can we distinguish them

一材质。

A material.

1、标准餐盒：采用100%PP食 品 级新料，环保安 全 零添加。（纯PP料厚薄均匀，原色通透，弯折有弹力韧性）

1. Standard lunch box: 100% PP food grade new material, environmental protection and safety zero addition（ Pure PP material has uniform thickness, transparent primary color, elastic and toughness when bending

2、劣质餐盒：再生料加非食 品 级填充剂，或是过量添加混合使用。（其多为灰黑色，加入填充剂后色泽不匀，厚薄不一，添加一般为白色或黑色，盖子多为加工成较软薄的透明PS料）

2. Inferior lunch box: recycled materials and non food grade fillers, or excessive addition and mixed use（ Most of them are grayish black. After adding fillers, the color is uneven and the thickness is different. The addition is generally white or black. The cover is mostly made of soft and thin transparent PS material.)

二设计。

Second, design.

1、标准：承重和抗压设计合理、相对的厚、重、硬，注重实用性四角倾斜度小，容量大。

1. Standard: bearing and compression design reasonable, relatively thick, heavy, hard, pay attention to practicality, small angle, large capacity.

2、劣质：材料软且薄，盒子较扁平，（生产简单，看上去大方），四个角倾斜度大，容量小。

2. Inferior quality: the material is soft and thin, the box is flat, (the production is simple, it looks generous), the four corners are inclined, and the capacity is small.

三工艺。

Three processes.

1、标准餐盒：采用有QS认证企业的机械设备，餐盒成型到位，美观有质感，盒与盖密契合度高密封有保证。

1. Standard lunch box: the mechanical equipment of QS certification enterprise is adopted, the lunch box is in place, beautiful and textured, and the fit between the box and the cover is high, and the sealing is guaranteed.

2、劣质餐盒：加工机械简单，为节省成本，工艺一步到位，餐盒成型不规整，边缘粗糙有毛刺，无揭盖半耳，盒盖密封度无保障。

2. Inferior lunch box: the processing machinery is simple, in order to save the cost, the process is in place in one step, the lunch box is irregular, the edge is rough, there is burr, there is no half ear of uncovering the cover, and the sealing degree of the cover is not guaranteed.

那消费者如何保障一次性餐盒的使用安 全？

How can consumers ensure the safety of disposable lunch boxes?

1、选择信誉度好的供应商，对产品出处要详细查证。

1. Choose a supplier with good reputation and check the source of the product in detail.

2、正规产品底部或盖子应拓印有QS认证编号和材质识别符号，如‘’符号，代表PP材质。

2. QS certification number and material identification symbol shall be printed on the bottom or cover of regular products, such as' symbol, which represents PP material.

3、在不了解产品性能的状况下，尽量避免在超过80摄氏度高温状态下使用。

3. If you don't know the performance of the product, try to avoid using it at a high temperature of more than 80 ℃.

4、购买时，选择安 全系数高的原色透明产品。

4. When purchasing, choose primary color transparent products with high safety factor.

5、加热时无臭味，不变形扭曲软化为安 全饭盒。

5. When heated, it has no odor, does not deform and softens into a safe lunch box.
