Pharmaceutical and Health Products

Tamper-evident bands, full-body sleeves, and unit-dose wraps for medicine and supplements.

Pharmaceutical and nutraceutical packaging uses PETG shrink film in two roles: tamper-evident neck bands that tear visibly once opened, and full-body sleeves that carry dosage text and barcodes on compact bottles. Low machine-direction shrink (MD ≤3.0%) keeps band height stable, so the perforation tears cleanly and the band cannot be reseated.

Where the pack must stay recyclable in the PET stream, CPET (TD 74±2%, RIC 1, melting point 230°C) lets the band or sleeve be recycled together with the PET bottle. The film is halogen-free and certified to GRS, REACH, and RoHS; the band wraps the closure exterior only and never contacts the medicine.

Frequently Asked Questions

What makes PETG suitable for tamper-evident shrink bands?

PETG's controlled, uniform shrinkage produces a clean perforation tear, so the band cannot be removed without visible damage — giving consumers proof the pack is unopened. Applied over the cap and neck, the band shrinks tight at 95-100°C. The CPET grade additionally lets the finished bottle recycle in the PET stream.

How do I size a tamper-band film to my bottle cap?

The film's layflat width is set from the cap-and-neck diameter the band must cover, plus a shrink allowance. Because we supply film in rolls slit to 200-2000 mm and cut to your layflat, you specify the finished band dimensions and we slit accordingly. Send cap diameter and neck profile for a recommendation.

Can the sleeve be recycled with a PET medicine bottle?

Yes, with the CPET grade. CPET carries Resin Identification Code 1, the same as PET bottles, and its 230°C melting point survives standard PET recycling, so the sleeve is recovered with the bottle instead of contaminating the stream.
