Is it true that plastic containers do not have a shelf life as they do not have a marked expiration date? It is reported that in March of this year, a survey report found that nearly 30% of plastic lunch boxes that can be heated in microwave ovens release plasticizers. This also means that plastic container products have a shelf life and will age after expiration. In addition, plastic bottles made from PET raw materials have previously been exposed to contain carcinogens - heavy metal antimony, and PET raw materials are now commonly used as packaging materials in beverage transportation. Even if the product is qualified, there is a potential risk of adding antimony to the human body if it is used beyond the expiration date.

Actually, it's not that plastic bottles have no shelf life, but the shelf life changes with people's usage methods. It is common for plastic containers to remain unchanged for several years until they are damaged. Let's take plastic trays as an example to illustrate their shelf life.

I only heard that the production date is indicated, but I haven't heard of the shelf life. During the visit, some plastic product sellers took several products, whether it was water bottles or washbasins, none of which had a shelf life. Subsequently, the manufacturer was contacted and the staff responded that the country only requires labeling of materials, uses, production dates, precautions, etc., without a shelf life.

When asked how long plastic products can be used in shopping places such as supermarkets in the city, most salespersons give the answer: "If they break down, replace them, and if they don't break down, continue to use them. We really don't know how long they can last

How long is the shelf life of a plastic product? The different usage conditions and cleaning methods of plastic products have an impact on their "lifespan". Although there is currently no clear regulation on the shelf life of plastic materials, the industry has a general idea that the shelf life of most plastic products is between three to five years.

Food grade plastic products in daily life should be replaced every two years. After using them for a period of time, it is necessary to check whether they have changed color, become brittle, and whether there are any bumps or depressions inside. If such conditions occur, they should be replaced in a timely manner. However, plastic tray manufacturers advocate replacing them every year, as the safety hazards that exist after a year of use have already existed.
