A PET cap is essentially a bottle cap made of polyethylene terephthalate (PET)-the same lightweight, transparent material used for mineral water bottles. Its key features include:
Resistance to acids and alkalis, and immunity to deformation-making it suitable for carbonated drinks and fruit juices
Excellent sealing performance-no leaks even when turned upside down or shaken
Availability in a wide range of colors, plus the option for laser-engraved anti-counterfeiting markings
