Plastic water bottles are popular among people of all ages because they are convenient to use and carry. However, there is a concern that the chemicals in the plastic may seep into the water and be harmful to our health. Then we should pay attention to the following points when purchasing plastic cups.
1. Look at the material. The first thing to look at when purchasing plastic water cups is the material of the water cup. The material of the water cup determines the quality of the water cup. Generally speaking, the silicone resin is better, followed by polypropylene particles (pp). This kind of material has strong resistance to high temperature and low temperature. The temperature resistance range of the former is – 40 ℃ – 200 ℃, and the latter is – 20 ℃ – 120 ℃.
2. See the purpose. The body of the water cup will be marked with the purpose, so the water cup should be “for food”. The cup marked with other purposes should not be purchased as far as possible, otherwise it will have adverse effects on health, and it is also not recommended to buy plastic cups without marked purposes.
3. Smell. A good plastic water cup will not smell very special even if it is new, but some inferior plastic cups can smell pungent inferior plastic or rubber smell as soon as they are close to it, which means that this cup is of poor quality and should not be purchased.
4. Look at the production license sign. Before the production of the water cup, a special agency needs to issue a license, so the bottle body of the water cup will be marked with the “QS” production license mark. Although this mark does not determine the quality of the cup, the water cup with this mark can be considered for purchase. In addition, the color of the logo should be clear and beware of fake and inferior.
5. See the manufacturer. The water cups produced by regular manufacturers will clearly indicate the specific manufacturer, production address, dealer, specific contact information, etc., while the above information of inferior water cups is often ambiguous, or there is no similar information at all.
