The use of disposable packing box is very common. The high quality secondary lunch box will not affect people's health and life in the process of use. So how do we determine its quality?

1、 從顏色的角度來看，一次性餐具的透明度是玻璃制品的幾倍，表面光滑。而劣質(zhì)的一次性餐具由于采用了再生原料，導致透明度低，表面光澤暗淡。

1. From the perspective of color, the transparency of disposable tableware is several times that of glass products, and the surface is smooth. And inferior disposable tableware due to the use of recycled raw materials, resulting in low transparency, dull surface luster.

2、 硬度方面，兩個一次性打包盒倒放，可承受一個成年人(約130-140斤)的重量。

2. In terms of hardness, two disposable packing boxes are placed upside down, which can bear the weight of an adult (about 130-140 Jin).

3、 從清潔的角度來看，由于一次性打包盒是一次性的，使用前只需檢查是否有水漬、殘留物和指紋，就可以確定是否是二次使用的餐具。

3. From the point of view of cleaning, since the disposable packing box is disposable, it only needs to check whether there are water stains, residues and fingerprints before use to determine whether it is a second use tableware.
                  

4、 區(qū)別于氣味，高品質(zhì)的一次性打包盒無毒無味。開水時不會有異味。這是消費者的保證。劣質(zhì)一次性打包盒會有刺鼻的氣味，對人體健康危害很大。

4. Different from smell, high quality disposable packing box is non-toxic and tasteless. There is no peculiar smell when boiling water. This is the consumer's guarantee. Inferior disposable packing box will have a pungent smell, which is very harmful to human health.

5、從原材料的角度來看：1、標準打包盒：100%聚丙烯食品 級新材料，環(huán)保安全零添加。(純PP材料厚度均勻，原色透明，彎曲有彈性和韌性)2、劣質(zhì)餐盒：回收材料加入非食品級填料，或過量添加和混合。(多為灰黑色，加入填料后顏色、厚度不均。一般情況下，填料為白色或黑色，蓋子加工成軟而薄的透明PS材料。)

5. From the perspective of raw materials: 1. Standard packing box: 100% polypropylene food grade new material, zero addition of environmental protection and safety（ Pure PP material thickness uniform, primary color transparent, bending elastic and toughness) 2, inferior lunch box: recycled materials added non food grade filler, or excessive addition and mixing（ Most of them are gray black, with uneven color and thickness after adding filler. Generally, the filler is white or black, and the cover is made of soft and thin transparent PS material.)

6、從設(shè)計的角度來看：1、標準：合理的承壓設(shè)計，較厚、重、硬，注重實用性，四角傾角小，承載能力大。2、質(zhì)量差：材質(zhì)松薄，箱體平整，(制作簡單，美觀大方)，四角傾角大，容量小。

6. From the design point of view: 1. Standard: reasonable bearing design, thick, heavy, hard, pay attention to practicality, small angle, large bearing capacity. 2. Poor quality: the material is loose and thin, the box is flat (simple to make, beautiful and generous), the angle of four corners is large, and the capacity is small.

7、從技術(shù)的角度來看：1、標準打包盒：采用QS認證企業(yè)的機械設(shè)備，打包盒到位、美觀、有質(zhì)感，盒蓋密封度高。2、劣質(zhì)打包盒：加工機械簡單，為節(jié)省成本，一步到位，打包盒成型不好，邊緣粗糙有毛刺，無蓋半耳，盒蓋密封程度不保證。

7. From the technical point of view: 1. Standard packing box: the mechanical equipment of QS certification enterprise is adopted, the packing box is in place, beautiful and textured, and the sealing degree of the box cover is high. 2. Inferior packing box: the processing machinery is simple, in order to save the cost, the packing box is not well formed, the edge is rough, there is burr, there is no cover half ear, and the sealing degree of the box cover is not guaranteed.
