1. Smell the taste first, the taste of PET is different from ordinary plastic. Use a lighter to burn it, and then you will smell a very aromatic and comfortable taste (just burn a bottle to smell), if the PET contains other ingredients, the taste will be very pungent .There are kinds of bottles containing SEBS ingredients that cannot be used.
2.Look at the burned part. If it is distributed black or the oil drops quickly, most of the melting points are abnormal, which is often found in PET film.
3.Draw the silk. When it is burning, pull the silk on the lighter to see if the length of the silk is long, and then break the pulled silk, see the break point in the middle, whether the silk is rolled into a small circle, the more the roll is It often means that the melting point is high. However, in general, if it is a bottle flake, there should be no big problem. The most important point is to distinguish whether it contains PVC, which is a fatal injury to PET.
4. Take more samples and spread them in a sunny place. The PVC will be light blue in the sun. If you fold in half, there will be white creases.
