Recently, after drinking Nongfu Spring, I found a triangle number on the inside of the bottle cap, which should mean recyclable. What does it mean to have a 02 in the triangle?
The triangle represents recyclable. "02" stands for HDPE (high density polyethylene), which is the material of plastic containers or plastic bags commonly used in shopping malls to hold cleaning supplies and bath supplies. It can withstand the high temperature of 1 10℃. If it is marked as edible, it can be used to hold food. Plastic containers containing cleaning products and bath products can be reused after careful cleaning, but they often leave residues because of poor cleaning, thus becoming a hotbed of bacteria. Different from other beverage bottles, the bottle bottom of 4L Nongfu Spring is marked with 02.
