Recently, after the Internet celebrity Big Belly Cup was criticized by many bloggers, many readers left comments below our video, asking us to identify the quality of the water cup in their hands and whether it can hold hot water. We can understand everyone’s thoughts and behaviors and answer your questions one by one. At the same time, we have singled out the most popular questions and shared them with you. The question is, what about the plastic water cup with the number 7+TRITAN on the bottom?
There are many types of plastic raw materials. The plastic materials used in the production and processing of water cups must be environmentally friendly, such as PP, PS, AS, PC and other plastic materials.
Products processed with different properties of plastic materials are also different. Even food-grade materials have requirements for use environment, material and temperature. The above-mentioned materials will not cause problems when drinking drinks with cold water or water cups not exceeding 60°C. The materials do not release any harmful substances. But breaking their physical requirements and being uniformly dissolved in a certain amount of water, a large amount of bisphenol A is released.
At the same time, due to the high hardness of some plastic materials and poor resistance to temperature differences, they may cause cracks during use. After being used for a long time like this, the cracks in the water cup will inevitably absorb some dirt in the water, and such a water cup cannot be used for a long time. Especially for disposable water bottles, please check the bottom label. Most of them cannot be used multiple times.
Due to the above-mentioned problem that plastic materials cannot hold hot water, a new type of plastic material, tritan, has appeared on the market. It has been greatly improved in every aspect. First of all, there is no bisphenol A, and secondly, it has higher transparency, high temperature resistance and excellent impact resistance. We once conducted a test. Boiling hot water was poured into a training cup made of tritan. It did not release any toxic substances and the cup did not deform.
In some European countries and regions, due to plastic bans, there are very clear regulations on the sales of plastic water cups. Water cups that can enter the market must meet food grade and be environmentally friendly and pollution-free. Therefore, as we pursue health, manufacturers have begun to use better and safer materials for processing.
Water cups made of Tritan material have been put into the plastic water cup market for many years. In recent years, they have become popular in the domestic market. Many plastic water cup merchants have produced tritan materials, which are odorless and non-toxic. However, in order to win the market, the price of the cups is very cheap, but The price of tritan raw materials has always been very expensive, so when consumers buy plastic water cups, they should carefully identify the styles and materials online to avoid buying fake tritan material water cups.
