The benefits of consulting with a manufacturer experienced in custom label solutions do not end with shapes, sizes, or materials. Choosing an adhesive specific to your application is just as important, and your consultant should provide possible options and sample materials (based on the described use and requirements) until you find one best suited for the product’s intended use.
Here’s some tips to make your adhesive testing is as effective as possible:
- Test on the Final Material: Adhesive performance varies depending on the application surface. Test the samples on the same surface type that the final label will be sticking to.
- Match the Application Conditions: Clean surfaces, oils, dust, and temperatures all can affect adhesion in different ways. So for example, if the final application environment is dusty and hot, then the test should replicate that.
- Use Pressure: The adhesive is pressure sensitive. Pressure will increase contact with the texture of the surface allowing for better adhesion. You can reduce air bubbles by applying that pressure on one end of the sample and working your way across to the other side.
- Let the Adhesive Cure: Initial tack and ultimate bond strength can be very different. In order for the sample’s adhesive to reach its ultimate bond strength, allow 48-72 hours for curing.
The bottom line: Adhesive testing is critical in determining which type is the best fit for your specific application. Consult with a manufacturer who will continue to provide you samples of various material configurations until you find the best combination for your intended use.
