Our human body needs to replenish a lot of water every day, especially after exercise and sweating, we must pay more attention to timely replenishment of water loss. For office workers, or elementary and middle school students, etc., you may have to bring a cup to drink water at your work or school every day. So how to choose plastic cups correctly?
1. Look at the material. The first thing you want to buy a plastic water cup is the material of the water cup. 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 is resistant to high temperature, The low temperature resistance is very strong, the temperature range of the former is -40 degrees-200 degrees, and the latter is -20 degrees-120 degrees.
2. Look at the purpose. The body of the water cup is marked with a purpose, so the water cup should be selected for "food use". Try not to buy and use cups marked for other purposes, otherwise it will have an adverse effect on health. Plastic cups that are not marked for use are also recommended.
3. Smell the 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 this cup is very poor, try not to buy.
4. Look at the production license sign. Before the production of water cups, a special agency must issue a license. Therefore, the bottle body 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. The water cups produced by regular manufacturers will clearly indicate the specific manufacturer, production address, distributor, specific contact information, etc., while the above information for inferior water cups is often ambiguous, or there is no similar information at all.
