In the previous article, I told my friends what are the characteristics of unqualified stainless steel thermos cups. Today, let’s talk about what are the characteristics of poor quality plastic water cups? When you read many of our articles and find that the content is still valuable, please pay attention to our website. When the news is released later, you will receive the information as soon as possible.
Plastic water cups have experienced decades of development to the present. Not only are their functions more diverse, but the development of materials is also changing with each passing day. From the early promotion of polymer materials (AS) to now, there are more than ten kinds of plastic materials used to make plastic water cups. There are AS ones, PC ones, PP ones, PS ones, PCTG ones, LDPE ones, PPSU ones, SK ones, TRITAN ones, resin ones, etc. Today I will not focus on any one type. Materials are explained, and only the common characteristics of poor-quality water cups produced from these materials are explained to friends.
1. Serious odor
Many friends bought plastic water cups and then smelled the odor and thought it would disappear after cleaning and drying it for a while. However, they found that the water cup still had a serious odor after being left for half a month. There must be something wrong with such a water cup. What is the cause of the odor? There are many kinds, but in the final analysis, the plastic materials used in the production of water cups are not purely contaminated, resulting in poor quality and low grade materials.
2. The water cup is seriously deformed.
Deformation not only refers to the appearance of the water cup, such as the cup lid, cup body and various accessories of the entire water cup. Severe deformation will directly affect the use of functions, and particularly severe cases may cause accidental injuries.
3. Cracks.
After purchasing a plastic water cup, friends must confirm whether there are any cracks in the water cup, because some water cups are light in color or transparent, and it is difficult to detect such water cups without inspecting them under a strong light source. To cause cracks in the cup body, the water cup must have experienced a serious impact. will cause this situation. Therefore, after receiving a new plastic water cup, friends carefully look at the empty cup against a strong light source to check whether there are any cracks.
4. Dirty.
Dirt is the most common phenomenon in poor-quality water cups. Dirt includes fingerprint marks, oil stains, plastic residue, dust, printing ink, spray paint particles, etc. Whether a good water cup is a plastic water cup, a stainless steel water cup, or a water cup made of other materials, water cups with these problems will be selected before leaving the factory and will not flow to the market.
5. Impurities.
The impurities mentioned here are not dirt. These impurities will appear in the cup body material and the cup lid material. The specific manifestation is that there will be mainly black dirty spots in the transparent cup body or cup lid material. Cannot be removed by washing. On the colored cup body or cup lid, there will be variegated spots that are obviously different from the color of the cup body or cup lid. For water cups with this kind of phenomenon, the editor recommends that friends return them rather than replace them with the same type of water cup. The reason for this phenomenon is that when producing plastic water cups, some manufacturers add recycled materials to new materials in order to reduce production costs. For the explanation of recycled materials, please read the article previously published by the editor. Since this water cup has recycled materials added during production, you can imagine that if you replace the water cup with the same model, this water cup will still contain recycled materials.
6. The color of the cup body is dark.
The dark color of the cup body is also the most difficult thing for many consumers to detect. The more transparent and colorless the water cup is, the easier it is to find it. The more opaque the color, the easier it is to find. The editor will share a little experience. How to judge whether the color of a plastic water cup is darkened. Where is Wu? Take the transparent and colorless plastic water cup as an example. When looking at the color of the water cup, try to find a clean glass water cup for comparison. If it can achieve the effect of a glass water cup, it means there is no problem with this plastic water cup. If you find that the gloss is obviously not as good as the glass water cup. , that means the color of this water glass is black. In addition to a small number of reasons for the production process, the reason for blackening is mostly caused by adding too much recycled material to the production materials.
