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.

Key Features

  • Strong adhesive designed for PET cap and neck surfaces.

  • Tamper-evident tear or stretch behavior upon cap rotation.

  • Film conforms to curved bottle shoulders without lifting.

  • Moisture- and scuff-resistant for distribution and shelf handling.

  • Compatible with high-speed applicators and manual sealing.

  • Suitable for branding, batch codes, and safety messaging.

  • Durable synthetic construction maintains integrity during transit.
