Adhesive, not face material, is why labels fall off
Lifted corners, poor grip, and labels that fall away whole almost always trace back to an adhesive that does not match the surface and temperature. The face material controls print sharpness; the adhesive controls holding power, so the two are specified separately.
The five adhesive families used in industry
| Type | Strength | Typical use |
|---|---|---|
| Permanent | Bonds for good, leaves residue when removed | Product and logistics labels |
| Removable | Peels cleanly | Price tags, temporary tags, restickered stock |
| Freezer and deep-freeze | Stays tacky below zero | Cold stores and frozen food |
| High-tack | Grips curved or rough surfaces | Plastic bins, curved packaging, recycled board |
| Wash-off | Releases with water or a specific bath | Returnable containers that are washed |
Cold store labels depend on application temperature
The rule that matters is the temperature of the label and the surface at the moment of application, not the temperature of the product. If goods are already frozen, either use an adhesive rated for low-temperature application or let the surface return to ambient before labelling.
Four adhesion checks before production
- Apply to the real surface at the real operating temperature and leave for at least 24 hours.
- Pull a corner back at 90 degrees and see whether the adhesive stays on the surface or lifts with the label.
- Chill or freeze for two hours, then check that the face is flat with no lifted corners.
- Wipe with the water or alcohol the site actually uses.
MNARA keeps adhesive samples across these families so the choice can be proven on your surface and temperature cycle before volume ordering.
