1. The purpose.
The cup body of the water cup is marked with a purpose, so the water cup should be selected for "food use", and the cups marked with other purposes should not be purchased and used, otherwise it will have an adverse effect on health. Do not buy plastic cups that are not marked for use.
2. Material.
The material of the water cup determines the quality of the water cup. Generally speaking, silicone resin is better, followed by polypropylene particles (pp). This type of material has strong resistance to high temperatures and low temperatures. The temperature range of the former is- 40 degrees-200 degrees, the latter is -20 degrees-120 degrees.
3. Smell.
Good plastic water cups will not smell very special even if they are new, but some low-quality plastic cups can smell pungent inferior plastic or rubber smell as soon as they are close, indicating that the quality of the cup is very poor, try not to Buy.
4. Production license sign.
Before the production of water cups, a special agency is required to issue a license. Therefore, 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, only water cups with this mark can be considered for purchase. And the color of the logo should be pure and clear, and beware of fakes.
5. Look at the manufacturer, address and contact information, etc.
The water cups produced by regular manufacturers will clearly indicate the specific manufacturer, production address, distributor, and specific contact information. The above-mentioned information for inferior water cups is often ambiguous, or there is no similar information at all.
6. Observe the number on the bottom of the cup.
Generally, plastic products have clear numbers on the bottom. The ones that are used as water cups are more assured that the number 5 or 7,5 is PP polypropylene, with a melting point of up to 167°C. It is the only plastic product that can be placed in a microwave oven and can be cleaned carefully. Repeat afterwards. 7 is other types of PC, common water bottles, space cups, baby bottles, etc. However, the design of this kind of water cup is not good, and it is easy to release the toxic substance bisphenol A after heating, which is harmful to the human body. Therefore, it is safer to choose the water cup numbered 5 at the bottom.
7. Price.
Good quality plastic water cups are not cheap, costing tens of yuan at every turn, so the quality of very cheap plastic cups with a few yuan is difficult to guarantee. You can buy it when the plastic cup is on sale, and it can be cheaper. For our own health, we still choose high quality and low price.
