When you choose PET bottles, have you noticed that there will be some scratches on the surface? What is the reason for this? Generally, we can understand from four aspects, and here is an introduction to you. Check it out if you need to know!
1. After the injection molding of the Pet preform, it may be damaged due to a little residual temperature, and then scratches appear.
2. The prepared preforms may also collide during transportation, which is also one of the reasons for scratches.
3. The preform may be scratched due to kneading during the blow molding process.
4. When using PET bottled products, it may also cause damage if you are not careful. Like the Coke we often drink, it is likely to be scratched during the packaging process.
This is why we usually find scratches on the surface of PET bottles when we buy them. It is because of these reasons that problems occur.
