1. From the perspective of color, the transparency of high-quality disposable tableware is several times that of glass products, and the surface is smooth. Inferior disposable tableware uses recycled raw materials, resulting in low transparency and dull surface gloss.

2. In terms of hardness, two high-quality disposable packaging boxes placed upside down can bear the weight of an adult (about 130-140 pounds).

3. From a cleaning perspective, since the disposable packaging box is disposable, you only need to check whether there are water stains, residues and fingerprints before use to determine whether it is a second-use tableware.

4. Different from the smell, high-quality disposable packaging boxes are non-toxic and odorless. There will be no peculiar smell when boiling water. This is a consumer guarantee. Inferior disposable packaging boxes have a pungent smell and are very harmful to human health.

5. From the perspective of raw materials: 1. Standard packaging box: 100% polypropylene food-grade new material, environmentally friendly and safe with zero additions. (Pure PP material has uniform thickness, transparent original color, elasticity and toughness when bending) 2. Inferior lunch boxes: recycled materials are added with non-food grade fillers, or excessively added and mixed. (Mostly gray-black, the color and thickness are uneven after adding fillers. Generally, the fillers are white or black, and the cover is processed into soft and thin transparent PS material.)

6. From the design point of view: 1. Standard: reasonable pressure-bearing design, thicker, heavier, harder, focusing on practicality, small inclination angle of the four corners, and large load-bearing capacity. 2. Poor quality: The material is loose and thin, the box is flat (simple to make, beautiful and elegant), the four corners have large inclination angles, and the capacity is small.

7. From a technical point of view: 1. Standard packaging box: Using mechanical equipment from QS certified companies, the packaging box is in place, beautiful and textured, and the lid is highly sealed. 2. Inferior packaging boxes: The processing machinery is simple, and in order to save costs, it is done in one step. The packaging boxes are not well formed, the edges are rough and have burrs, there are no lids and half ears, and the sealing degree of the lids is not guaranteed.

How can consumers ensure the safety of disposable packaging boxes?

Choose a reputable supplier and verify the origin of the product in detail.

The QS certification number and material identification symbol should be printed on the bottom or cover of regular products, such as the "symbol" of PP material.

Without understanding the performance of the product, try to avoid using it at high temperatures above 80°C.

When purchasing, it is best to choose primary color transparent products with a high safety factor.

After heating, it has no smell, no deformation, and softens into a safe packing box.
