On very rare occasions, we hear from one of our customers that their labels are not adhering properly to an asset. There are several reasons this may happen, but here we’ll go through a few reasons this may occur and some quick tips on how to ensure your labels best adhesion.
Firstly, poor adhesion would not normally occur due to a bad batch of material used in the production process. Yes, this can happen but over more than 20 years of label production we’ve seen this happen less than a handful of times and material vendors have only improved the quality and reliability of their products during this time. Also, if your labels were part of a bad batch of material we would know almost immediately, as this would affect many of our customers who would quickly contact us if this were the case.
So, now we’ve dealt with material most other causes for poor adhesion will fall into three other categories; asset type, asset surface and application. For best adhesion results labels must have a good surface to adhere to. Surfaces such as glass, plastic and other flat box type assets are ideal and offer a smooth and consistent surface, but cardboard, fabric or tightly curved surfaces may not achieve the same level of adhesion. At Custom Labels we’re happy to provide samples of your label to test and in most cases, these can be dispatched the same day via next day delivery.
Another factor in adhesion quality is the condition of the surface it’s applied to. Contamination such as dust, oils or degreasing residue such as cleaning products will affect the labels bond. Assets and products must be cleaned before application including any residue leftover from any cleaning products.
The way in which the label is applied can also greatly affect adhesion. When labels are applied by hand, they can pick up oils from our skin which can create enough of a barrier to prevent proper adhesion, so minimising the amount of label handling prior to application can ensure an ideal bond. Also, many of our permanent labels require a curing time of 48-72 hours, so avoid testing the bond before the label has fully cured.
Some quick tips to applying your label for best adhesion:
Clean the area where the label is to be applied. The label needs to be applied to a clean surface to ensure the best adhesion. A surface can appear clean but may have dust, dirt or even a greasy finish (from human hands).
Using a small amount of methylated spirits or similar and a lint-free cloth, clean the area where the label is to be applied. Make sure the area is dry before applying the label. This will help the label to stick well to a clean surface, free of any grease or dust. Once the surface is clean, apply the label. Once the protective backing is removed, hold the label by the edges, be careful not to touch the exposed adhesive. Apply the label to your clean surface and press down firmly. Once applied please do not try to reposition it as this will reduce the labels cured adhesion.
