Should I choose PC or PP for plastic water cups?

There are various types of plastic water cups, and it is inevitable that we will be dazzled when choosing plastic water cups.

In order to let everyone know more about plastic water cups and be able to choose their favorite plastic water cups, let me focus on introducing to you the differences between PC and PP in plastic water cup materials.

PC is the English abbreviation of polycarbonate, one of the most common plastics. This material is non-toxic and is especially used to make baby bottles, space cups, etc. Because it contains bisphenol A, it has been controversial.

In theory, as long as 100% of the bisphenol-A is converted into a plastic structure during the manufacturing process of polycarbonate, it means that there is no bisphenol-a in the product at all, and there is no risk to health. However, if small amounts of BPA are not converted into the plastic structure of polycarbonate, it may be released into food or beverages, threatening the health and safety of users, especially teenagers.

PP is the English abbreviation of polypropylene and has good heat resistance. The product can be sterilized at temperatures above 100 degrees Celsius and will not deform at 150 degrees Celsius without external force.
Polypropylene is one of the most commonly used plastics in microwave ovens. However, after careful investigation, we will find that polycarbonate on the market is often more expensive than polypropylene products, and customers tend to follow the concept of “the more expensive, the better the quality”. In fact, the price difference is because the current price of a ton of polycarbonate on the market is much higher than the price of a ton of polypropylene.

Comparing the two materials, it can be found that polypropylene has worse wear resistance than polycarbonate, so when making transparent cups, polycarbonate is generally used as the material. Polycarbonate products are more beautiful than polypropylene products. However, from a safety point of view, the processing temperature of polypropylene plastic reaches 170 ~ 220 degrees Celsius, so boiling water cannot decompose it, so polypropylene is safer than polycarbonate.
