How to choose plastic cups correctly- Yuyao Sanfeng Plastic Mold Co., Ltd.

1. Look at the materials

The first thing to look at when choosing a plastic water cup is the material of the water cup. The material of the water cup determines its quality of the water cup. Generally speaking, the silicone resin is better, followed by polypropylene particles (pp). This type of material is resistant to high temperatures, The low-temperature resistance is very strong, the temperature resistance range of the former is -40 degrees --- 200 degrees, and the latter is -20 degrees --- 120 degrees.

2. Look at the purpose

The water cup body will be marked with the purpose, so the water cup should be selected as "food use". Try not to buy and use cups marked with other purposes, otherwise, it will have adverse effects on health. It is also recommended to buy plastic cups without marking purposes.

3. Smell

A good plastic water cup will not have a very special smell even if it is new, but some inferior plastic cups can smell a pungent inferior plastic or rubber smell as soon as you get close to it, which means 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 needs to issue a license, so the bottle of the water cup will be marked with a "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. Moreover, the color of the logo should be pure and the pattern clear, and beware of fake and shoddy ones.
