Correctly analyze the bottom numbers of chemical plastic drums

If you observe it yourself, it is not difficult to find the number at the bottom of the chemical plastic bucket. So what do these numbers imply? What are the differences between different numbers? We will provide a detailed introduction in the following content for everyone.

The number 1 represents that the plastic is made of PET. It has the characteristics of high transparency, acid and alkali resistance. It is currently the most widely used beverage bottle, but it cannot be placed in a car to bask in the sun, let alone contain substances such as alcohol and oil.

The number 2 represents that the plastic is made of HDPE. This material is resistant to various corrosive solutions and is commonly used in cleaning and bathing products. It is often used in white medicine bottles and opaque shampoo bottles. But these containers are usually not clean, and residual substances can become a breeding ground for bacteria, so it is best not to recycle them.

The number 3 represents PVC material, which can only withstand heat up to 81 ℃ and is prone to producing harmful substances at high temperatures. Currently, it is rarely used in food packaging. If PVC material is used for food containers, it is best not to purchase it.

The number 4 represents LDPE material. It is commonly used for packaging plastic wrap, toothpaste, or facial cleansers in flexible tubes, but it can melt when the temperature exceeds 110 ℃. Therefore, before putting food into the microwave, the wrapped plastic wrap must be removed first. Above, we mainly introduced the situation of numbers 1-4 at the bottom of chemical plastic drums. We hope the above introduction is useful to everyone.
