In March this year, the Hong Kong Consumer Council released an investigation report that nearly 30% of plastic lunch boxes that can be heated by microwave ovens will release plasticizers. This also means that plastic container products have a shelf life and will age after expiration. In addition, the plastic bottle made of PET has previously been exposed to the carcinogen heavy metal antimony, and PET is currently the packaging material used in drinks. Even if the product reaches the standard, the potential risk of antimony to human body may be increased if the product is used beyond the time limit.
How many years are plastic cups commonly used?
Recently, Xiao Bian interviewed more than 20 citizens randomly, none of whom could tell the shelf life of plastic container products. In the survey, common food grade plastic products have been used for more than three or four years.
"I only heard about the production date, but I haven't heard about the shelf life." During the visit, some sellers of plastic products showed the reporter several products. No matter the cups or washbasins, they had no shelf life.
Later, the reporter contacted the manufacturer according to the contact information on a plastic water cup, and the staff replied that at present, the country only requires to mark the material, purpose, production date, precautions, etc., and there is no warranty period.
In shopping places such as supermarkets in urban areas, when the reporter asked how long the plastic products could be used, most of the shopping guides replied: "Change one if it is worn out, and continue to use it if it is not worn out. We really don't know how long it can last."
Remind me to use it frequently. It is recommended to change it every two years
How long is the shelf life of a plastic product? Experts said that the use and cleaning methods of plastic products are different, which has a certain impact on the "life" of plastic products. Although there is no explicit stipulation on the plastic shelf life of which material, there is a general statement in the industry that most plastic products have a shelf life of three to five years.
Experts suggest that food grade plastic products in daily life should be replaced every two years. After using them for a period of time, it depends on whether they change color, become brittle, and whether there are bumps in the interior. If there is such a situation, they should be replaced in a timely manner.
