Cap Seal Label – PET Bottles
PET bottle caps are frequently tampered with or loosened during transport, retail handling, or storage. Basic stickers do not provide reliable tamper indication—they tear irregularly, peel cleanly, or fail to show whether the seal was broken. PET bottles also present a smooth, low-energy surface that many adhesives struggle to bond to. Anaika’s Cap Seal Labels for PET Bottles use engineered films and high-tack adhesives that fracture or stretch visibly upon opening, ensuring clear tamper evidence and secure sealing from filling line to end-user.
