Occasionally, we receive feedback from our customers about labels not adhering as expected to their assets. While this is a rare occurrence, it’s crucial to understand the reasons behind it and learn some tips to ensure the best label adhesion. In this guide, we will explore why poor adhesion can happen and provide practical suggestions to optimize label adhesion.
Material Quality Assurance
Adhesion issues are seldom linked to the quality of materials used in label production. Over our two-decade history in label production, we’ve encountered this problem only a handful of times. Moreover, material suppliers have consistently improved the quality and reliability of their products. If there were ever a problem with the material batch, it would likely affect multiple customers, leading to swift resolution.
Factors Influencing Adhesion
Now, let’s delve into the primary factors that can impact label adhesion, falling into three categories: asset type, asset surface, and application.
Asset Type
For labels to adhere optimally, they require a suitable surface. Materials like glass, plastic, and flat-box assets offer ideal, smooth, and consistent surfaces. However, materials such as cardboard, fabric, or tightly curved surfaces may not provide the same level of adhesion. At Custom Labels, we’re pleased to offer label samples for testing, which can typically be dispatched the same day via next-day delivery.
Surface Condition
The condition of the surface to which labels are applied is critical. Contaminants like dust, oils, or residue from cleaning products can compromise label adhesion. Prior to label application, assets and products should be thoroughly cleaned to remove any residue from cleaning products or other contaminants.
Application Method
The manner in which labels are applied also significantly affects adhesion. Hand-applied labels can absorb oils from the skin, creating a barrier that prevents proper adhesion. To ensure an ideal bond, minimize label handling before application. Additionally, many of our permanent labels require a curing time of 48-72 hours, so refrain from testing the bond before the label has fully cured.
Quick Tips for Optimal Label Adhesion
Surface Preparation:
Clean the area where the label will be applied. Ensure it is free from dust, dirt, or greasy residue.
Use a small amount of methylated spirits or a similar cleaner and a lint-free cloth to clean the application area.
Ensure the surface is completely dry before applying the label, as this promotes strong adhesion.
Proper Application:
When removing the protective backing, hold the label by the edges, avoiding contact with the adhesive side.
Apply the label firmly to the clean surface.
Avoid attempting to reposition the label after application, as this can reduce the label’s cured adhesion.
By understanding the factors affecting label adhesion and following these simple guidelines, you can ensure that your labels adhere correctly, maintaining the integrity of your assets and products.
