The recyclable paper cups sold in general supermarkets now have the production date and shelf life printed on them, and the shelf life of different paper cups is also different. Some paper cups can have a shelf life of up to 5 years. So how should we choose when buying paper cups?
First of all, we need to see whether the information marked on the packaging is complete, whether the production license number and QS logo are marked. Secondly, the outline of the printed pattern on the outside of the good quality paper cup is clear, the color is uniform, and there is no obvious color spot. Qualified paper cups cannot have printed patterns within 15 mm from the mouth of the cup and 10 mm from the bottom of the cup to the body of the cup. Third, pay attention to the production date and shelf life.
We can also gently squeeze the sides of the paper cup to roughly know the quality of the cup's body. Generally, high-quality paper cups can be filled with water for 72 hours without leakage, while the poor quality will see water in half an hour.
Finally, we can smell the pungent smell of the paper cup, especially the smell of ink or moldy smell. Please do not buy the smelly paper cup. The quality of disposable paper cups on the market is uneven, and most households are improperly stored, which makes the cups susceptible to dampness and mold, causing the growth of bacteria and fungi. If used at this time, it will cause certain harm to the human body. The moldy and damp paper cups should be replaced and discarded in time.
