Recently, I had two customers with issues of the labels adhering to
their containers.

| Labels Adhering Improperly |
In the process of investigating these adherence issues, I learned
something about labels that I wanted to share.
As background, both of these labels were made of paper. Plus both were
being applied in relatively cool warehouse temperatures as it is winter. Also, these labels were relatively large;
some over 11” long. Lastly, the paper
and adhesive (a true high performance adhesive) is a very large selling label
product, with a large volume production.
It’s used across the world.
After learning of the issues, we contacted the original manufacturer of
the paper labels; and had them test the adhesive. During the tests, they learned the adhesive
was applied consistently; no issue.
However, they asked, “how was the label applied?” From this question, I learned how you apply
the label makes a difference in adhesion.
According to the manufacturer, “In the photos, it looks like it is the
same corner is lifting. One or two corner edge lift is often caused by how the
label is removed from the liner. Believe it or not there is a correct and
incorrect way to remove a label from the liner.”
Continuing, the manufacturer said, “The incorrect way to remove a label
from the liner will break the paper fibers resulting in one or two corners
of the label lifting away from the application surface over a period of time. Do not pull the label back against itself,
this results in a tight curl which breaks
paper fibers and induces label edge lift – see photos.”

“The correct way to avoid label adhesion issues is to remove the liner
from the label.
Adequate pressure needs to be applied across the entire label to ensure
adhesive contact with the surface of the substrate being labeled”, stated the
manufacturer.
Once we learned of this application technique, we were able to
replicate the adherence issue ourselves:
To help further, we found a video from Datamax O’Neil on the proper way to separate the liner from the paper.
Who knew this technique could make such a big difference!
Please know; I’m not saying application will solve all
adhesion/adhesive issues involving labels.
But you can improve the look and function of labels with proper
application.
