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

In the last article, the editor shared the way of "checking" to judge whether the plastic water cup is qualified or not. So today editor shares other ways to identify whether the plastic water cup is a substandard product.

In addition to the way of seeing, we also need to use the way of smelling, this editor recommends that you use the three-way method.

First, when you open the box of the water bottle, smell it to see if there is an unpleasant odor. I believe that the plastic water cups purchased by some friends will have a pungent smell when opened. If there is a serious taste after opening the package, it can basically be judged that there is a problem with the material of this water cup and it does not meet the food-grade standard.

There is no obvious smell after opening the package, we can open the lid of the water cup and smell it. If there is a pungent smell after opening, it also means that there is a problem with the material of the water cup, and the pungent smell is usually caused by the material not meeting the standard. This includes the poor quality of the material itself, or the addition of too much return material in the raw material, or the material pollution caused by the negligence of material management in production management.

Some friends couldn't help but ask, opened the lid of the cup and smelled it, and found that there was a smell, but it was not very pungent, and some still had a faint smell of tea and other smells. In this case, how to judge whether the water cup material is suitable and qualified, and whether it can be used normally?

Then we will smell the third time, some manufacturers know that their products have problems. In order to prevent consumers from discovering that the products are unqualified by smelling the smell, these factories will dry the water cups produced for a long time, and evaporate the smell through drying. In order to further cover up the packaging, a "tea bag" type desiccant with a tea-like aroma is added to the empty cup, and the unpleasant taste is covered by the volatilization of the aroma. The water bottle with no problem with the material is usually filled with odorless desiccant.
