Paper cups have a shelf life, ranging from 1 to 5 years. If the shelf life is exceeded or the storage and transportation conditions are improper, it will cause the aging of the film, resulting in the overflow of microplastics. There may be problems such as excessive heavy metal ions.


Unqualified paper cups do pose health risks. For example, raw materials are moldy or contaminated during transportation and storage, the quality of printed inks is not up to standard, and chemical additives are not used in the surface treatment of paper cups, which may bring health risks, such as chemical components, inks, microplastics, etc. directly or indirectly endanger the user.


Avoid vinegar and wine


Qualified disposable paper cups are light, hygienic, and odorless. If you want to buy paper cups, you should choose the ones that are sealed in plastic bags, have the QS logo, and are within the shelf life.


When using all paper cups, the following 2 types of food should be avoided:


Vinegar and soda. Experiments have shown that acetic acid may leach some chemicals out of polyethylene films. Therefore, try not to use disposable paper cups to hold vinegar. Try not to use them for a long time to drink juice or carbonated beverages.


Alcohol and alcoholic beverages. Some studies have found that using a paper cup to hold alcohol with a concentration of more than 45% for more than 2 hours will greatly increase the content of chemical substances in the wine. Moreover, alcohol may also dissolve some components in the ink on the surface of the paper cup, which is not good for health.


In addition, there are two types of disposable paper cups: paper cups made of cardboard and waxed paper cups. The former is mainly used to hold dry things and cannot be used to hold water and oil. The latter is waterproof because it has been coated with wax, but it cannot hold hot water. No matter what kind of paper cup, it is recommended not to reuse it. Try not to heat it in a microwave oven, so as not to cause the local temperature in the cup to be too high and the precipitation of chemical substances. Therefore, if the outer packaging of the paper cup doesn't indicate that it can be microwaved, don't heat it.
