Polyethylene Terephthalate (PET) is a high-performance thermoplastic polymer widely used in holographic security labels, synthetic labels, stickers, and bags. Known for its durability, clarity, and resistance to moisture and chemicals, PET provides an ideal surface for holographic embossing, printing, and metallisation. Its versatility allows for tamper-proof labelling, high-gloss branding, and protective packaging solutions, ensuring security and premium presentation.
