What are the characteristics of plastic cups with poor quality?

In the previous article, Editor told friends about the characteristics of unqualified stainless steel insulation cups.Today, let's talk about the characteristics of plastic water cups with poor quality?If you like this article, please click like it to encourage editor to continue to bring you practical content related to water cups.When you watch the small articles and find that the content is still useful.Please pay attention to the editor. You will receive the information as soon as the new article is released.

After decades of development, plastic water cups are not only more versatile in function, but also rapidly changing in material development.From the early publicity of polymer materials (AS) to today's plastic cups, there are more than ten kinds of plastic materials, including AS, PC, PP, PS, PCTG, LDPE, PPSU, SK, TRITAN, resin, etc.Today's editor does not explain a certain kind of materials, but only the common features of the poor quality water cups produced by these materials.

1. Severe odor

Many friends bought plastic water cups and then asked about the smell. They thought it would disappear after a period of washing and drying.It was found that the cup still had a serious odor after half a month of storage, so there must be something wrong with the cup.There are many reasons for the odor, but in the final analysis, the plastic material used to produce the cup is not pure and polluted, resulting in low quality.

2. The water cup is severely deformed.

Deformation not only refers to the appearance of the cup, such as the cup cover, the cup body and all the accessories of the entire cup.Serious deformation will directly affect the use of functions, and especially serious deformation will cause accidental injuries.

3. Cracks.

Friends must confirm whether the plastic water cup has cracks after buying it.Because some water cups are light or transparent, it is difficult to find such water cups without checking against a strong light source.The crack on the cup body must be caused by severe impact on the cup.So after receiving the new plastic water cup, the friends carefully looked at the place where the empty cup was facing the strong light source to check whether there were cracks.

4. Dirt.

Dirt is the most common phenomenon in poor quality water cups.Dirt includes fingerprints, oil, plastic residue, dust, printing ink, spray paint particles, etc.Good cups, whether plastic, stainless steel or other materials, will be selected before leaving the factory and will not go to the market.

5. Impurities.

The impurities mentioned here do not belong to dirt. These impurities will appear in the cup body material and also in the cup lid material.The specific performance is that there will be black stains in the transparent cup body or lid material, which cannot be removed by cleaning.There will be variegated spots on the colored cup body or lid that are obviously different from the color of the cup body or lid.For water cups with this kind of phenomenon, I suggest friends return them rather than replace them with the same type.

This phenomenon is caused by the fact that when producing plastic water cups, some manufacturers have added recycled materials to the new materials in order to reduce production costs. Please refer to the previous articles published by the editor about the recycled materials.Since this water cup has been added with recycled materials during production, you can imagine that whether you replace the same water cup or add recycled materials.

6. The colorless transparent cup body is black.

It is also the most difficult for many consumers to find the colorless transparent cup body with dark color.The more transparent and colorless the glass is, the easier it is to find it. The more opaque the glass is, the easier it is to find it.editor shares a small experience, how to judge whether the color of the plastic water cup is black?

Take the transparent and colorless plastic water cup as an example. Try to find a clean glass water cup for comparison when watching the color of the water cup.If it can achieve the effect of glass water cup, it shows that this plastic water cup is no problem.If it is found that the luster of the glass cup is obviously inferior to that of the glass cup, it indicates that the color of the glass cup is black.In addition to a small part of the production process, the cause of blackening is more due to the addition of too much recycled materials in the production materials.
