Trouble Shooting

1) How quickly will the tamper evident feature be functional?
For the recommended surfaces and an application temperature of 20C (or higher), the tamper evident feature (OPENED) should function within 10 seconds, but we recommend to allow 2 minutes.
Applying labels at temperatures less than 20C may require more cure or wetting out time on the surface,

2) After 1 minute, the security label can be removed cleanly and it does not show the tamper evident message (VOID OPENED). What's the problem?

Let's work through the checklist...

  1. Confirm the surface is on the "RECOMMENDED SURFACES" list for the label you purchased.
  2. When applied, the surface must be a MINIMUM of +5C. To confirm if temperature is an issue, temporarily move to a location where the surface can achieve a higher temperature (ideally +20C or higher) and test again.
  3. The surface must be dry. Moisture of any kind can cause a problem. Dry thoroughly with a clean paper towel and repeat the test.
  4. The surface must be clean. Wipe with a clean cloth or paper towel to remove dust or other loose particles, and then repeat the test.
  5. If there are any possible chemical contaminants (oil, lubricants, 11release agents, waxes, etc.), clean the surface with 100% iso-propyl alcohol or acetone. Wipe the solvent dry with clean dry cloth or paper towel, and then repeat the test.
  6. If the surface has a clear coat or clear varnish, confirm if the varnish is still present after the label is removed. It is possible for the label to remove the clear coat if it is not bonded well to the underlying surface. If the varnish was removed, we recommend testing our low residue seal, which features a less aggressive adhesive.
  7. The surface may require a longer cure time. Smooth surfaces usually only require a 1 minute cure. Rough and textured surfaces usually require more cure time. Plastic and powder coated paint usually require more cure time. (I would not add this Jan)If you cannot identify the problem from the above steps, the label selected will not meet your needs. Please contact us for next steps.

3) I purchased low residue security seals, but it leaves an adhesive residue on the surface. What is the problem?

  1. When removing, to minimize any potential adhesive residue, peel the label at a sharp angle (180 degrees).
  2. For some "high energy surfaces" (like glass, uncoated stainless steel, etc.), the low residue may not function as a low residue seal.
  3. "Low residue" generally works in temperatures ranging from (Our low residue adhesive will only work at around zero degrees...possibly as low as minus 5 degrees, but would then need some time to wet out. We have a permanent hot melt adhesive that can be applied on frost free surfaces to maximum minus 10 degrees and then our new sub-zero permanent acrylic adhesive that is good up to minus 20 degrees) to 50C. For temperatures outside of this range, the low residue feature may be impaired and you may have to revert to a conventional security label that leaves an adhesive residue.
  4. If the labels remain on the affixed surface for more than 90 days, the low residue feature may be impaired and revert to leaving a residue, but due to the inherent characteristics of the adhesive, it can easily be rubbed off with a finger or cloth.
  5. If leaving an adhesive residue is a continuing issue, we have a "Low Residue" seal which leaves virtually no residue, depending on the surface that it is stuck onto.

4) How can I clean up the adhesive residue?

  1. Sometimes, if you rub the adhesive residue with your finger, it will roll up into a ball and it can be removed in a few seconds NB: only low residue adhesive. Permanent adhesive will not rub off).
  2. If the adhesive is more stubborn, you will need an adhesive solvent. An option is iso-propyl alcohol (100%) or acetone. Avoid using rubbing alcohol and nail polish remover-- it can leave an oily coating that will interfere with adhesion for the next label It is not easy to remove ‘dry peel’ residue as the adhesive is covered by a layer that is impervious to most solvents.

5) While applying the label, I touched the adhesive with a finger and it accidentally activated the VOID feature. How do I prevent ruining my security seals before they are affixed?

  1. If your fingers are dry, they may activate the VOID feature. Apply a small amount of hand moisturizer to your hands and fingers before handling the security seals.
  2. Minimize handling the label. Peel back the paper backing to "flag" the seal and expose the adhesive. Then apply to the surface without touching the adhesive.
