The difference between plastic packaging PET and PVC

Affected by the “plasticizer” turmoil in Taiwan, consumers are increasingly concerned about beverage safety. PET plastic bottles are safe, while PVC has security risks. According to research, not only the plastic bottle itself, if the outer package uses PVC, it may contain plasticizers, which penetrate into the beverage.

1. The "PET" logo is hard to find

Almost all of my carbonated drinks, milk tea, mineral water, and lactic acid bacteria beverages are plastic packaging.

Most beverage bottles have a triangle with a “1” or “2” number printed on the bottom of the bottle, and letters will be written around it. The number "1" stands for "polyethylene terephthalate" and the English letters for "PET". The number "2" stands for high-density polyethylene, and English for "HDPE". These plastic signs are mainly for convenience of recycling. If they understand it, consumers can use this label to know what materials they use and what they can do. The earliest company to use PET bottles for packaging beverages was the American Coca-Cola Company. They replaced one liter of glass bottles with 1.5-liter PET bottles, resulting in a 27% increase in retail sales. After that, the food and beverages packaged in PET containers have gradually become the mainstream of beverage packaging. According to statistics, at present, the proportion of PET used as a beverage packaging in China is about 57%. Because of its light material, high transparency, resistance to impact, it is not easy to break, and can be printed in text and pattern, so it is widely favored.
