Do plastic water cups have a shelf life?(Second)
Hello everyone, "Dong Dong Talks About Cups" is here. In yesterday's article, due to space constraints, Uncle Dong shared with you part of the content about whether plastic water cups have a shelf life. http://www.zhanyict.com/en/ProductsDetail-VB-10146.htmlToday I will continue to share with you the rest.
Some consumers use them for more than 5 years. It is precisely because of these situations that administrative agencies do not list the shelf life of plastic water cups. In addition, the shelf life we traditionally understand is that the texture of the product will change after the shelf life requirement, which will affect the safety of the product. http://www.zhanyict.com/en/ProductsDetail-VB-10146.htmlTherefore, there is currently no clear requirement for plastic water cups. However, as a water cup practitioner, based on my understanding of the performance of various plastic materials, plastic water cups actually have a shelf life in the strict sense. This shelf life includes the service life of the material, the material's bearing limit, and some factors that cause the material's performance to deteriorate, thus causing safety issues.
Since plastic water cups have no shelf life requirements, neither market managers nor consumers care much about the production date of the water cups. http://www.zhanyict.com/en/ProductsDetail-VB-10146.htmlAs a result, some plastic water cup manufacturers will wipe the water cups that have been in stock for many years and repackage them for sale. However, consumers cannot tell the difference, especially for water cups made of PP materials. In some places with high temperature and humidity, the products will become moldy after being stored for a long time, but this cannot be distinguished after being processed again by the factory.
The appearance of mold is the shelf life of the material. For example, PP material will usually begin to mold in a year in a hot and humid environment. For example, plastic material AS will quickly crack in areas with distinct seasons. http://www.zhanyict.com/en/ProductsDetail-VB-10146.htmlOnce this happens, it will not be possible to clean it thoroughly after each use, and there will be tiny residues in the cracks. In an environment with plenty of sunlight and frequent exposure, various plastic materials will age faster. For example, PC will be catalyzed by long-term exposure to ultraviolet rays in 8-12 months, greatly reducing safety.
After understanding the above content, I believe that friends will also enrich their judgment ability and safety awareness when using plastic water cups. http://www.zhanyict.com/en/ProductsDetail-VB-10146.htmlRegardless of the material of the plastic water cup, the editor recommends replacing it with a new one after 6-18 months of use. This way you can protect yourself more safely and healthily.
