1. Hot water test
You can rinse the plastic cup first and then pour hot water into it. If deformation occurs, it means the plastic quality of the cup is not good. A good plastic cup will not show any deformation or odor after being tested in hot water.
2. Smell
You can use your nose to smell the plastic cup to see if there is any obvious odor. If the smell is strong, it means that the plastic of the cup is of poor quality and may release harmful substances. High-quality plastic cups will not smell or produce harmful substances.
3. Shaking test
You can first pour some water into the plastic cup and then shake it. If the cup is obviously deformed after shaking, it means that the plastic quality of the cup is not good. A high-quality plastic cup will not deform or make any noise due to shaking.
