Tamper-Evident Seal – VOID Film (Pharma)
Pharmaceutical packs must show clear evidence of tampering. Standard labels peel cleanly or reseal without visible disruption, creating a compliance and safety risk. VOID films, when engineered correctly, transfer a hidden pattern onto the surface upon removal—but only if the adhesive and film chemistry are tuned for pharma substrates. Anaika’s VOID Tamper-Evident Seals are designed for pharmaceutical cartons, bottles, and blister packs, ensuring irreversible, visible tamper indication without damaging the pack or interfering with regulatory printing.
Key Features
VOID film transfers a tamper message when lifted, preventing resealing.
Engineered adhesive ensures reliable pattern transfer on coated cartons and bottles.
Film resists moisture, heat, and routine handling before activation.
Clean initial application with no bubbling or silvering.
Available in partial-transfer or full-transfer VOID formats.
Suitable for top lids, side flaps, bottle caps, and induction-seal overlays.
Printable surface compatible with batch codes, barcodes, and branding.
