How to identify unqualified plastic water cups “at a glance”? (two)

Here, I would like to emphasize again that there are many styles of plastic water cups and different structures. The editor can only try to find common points. If the editor must identify a certain type of water cup, friends, you can send the water cup that needs to be identified to the editor, and the editor will write a highly targeted article separately.

After reading the lid of the cup, we need to look at the body part of the cup. Many plastic drinking cups are transparent, translucent or frosted opaque. We need to look at the cleanliness of the transparent cup body, the closer it is to glass-level transparency, the better. Of course, different plastic materials have different transparency in the final product.

Here, the editor is talking about identifying whether the water cup is qualified or not, and does not evaluate other properties of the material, such as whether it contains bisphenol A or whether it can be used for high-temperature hot water. The transparency of the cup body will decrease after adding back material, and the more added, the worse the transparency. Although some water cups are new, it is found that the colorless and transparent appearance is indeed a bit foggy when you get it in your hand, which is mostly caused by adding a lot of recycled materials.

Most of the translucent plastic water cups are colored, so when we buy them, we try to make them lighter in color, which is also based on the standard of cleanliness and transparency.

For opaque water cups, the editor recommends buying light-colored ones. Because the darker the plastic water cup, the more it can't be seen after adding the recycled material, especially the black plastic water cup, even if a large amount of recycled material is added, it cannot be seen from the surface. However, the lighter the color and the more transparent the plastic water cup, the easier it is to arrange whether there is any added material in the cup body. The most obvious manifestation is that you will find the appearance of variegated colors in the material of the cup body, or the appearance of black spots.

As for how to identify after spraying paint on the surface of plastic water cups, this is the most difficult, and it is also possible to identify. Open the lid of the cup and look in from the mouth of the cup at the place where the light is strong. Usually the water cup itself with paint sprayed on the surface of the plastic water cup is transparent. Through the strong light, it is easy to find out whether there are impurities in the wall of the water glass.

Tomorrow, the editor will continue to share with you how to identify unqualified plastic water cups with one glance.
