Label Application
Storage:
Surface Preparation:
Application Temperature: There are many methods of application depending on the size of the label, the type of adhesive, the number of splits in the liner and the shape of the container.
Hand application: Small labels are usually applied by removing the entire liner, aligning the label so it is straight and press the label to the surface. Any bubbles or wrinkles can usually be worked out from edge to edge or center to an edge. Large labels will sometimes have multiple slits in the liner to allow partial exposing of the adhesive. This allows the labels to be applied by removing part of the liner to start the application. For this type of label, remove part of the liner, align the label so it is straight then with a slight curl attach the middle of the label to the surface, then work any bubbles or wrinkles to the edges. If the liner was not completely removed carefully remove the balance of the liner and work any bubbles or wrinkles to the edges. Some adhesives are highly aggressive and will not allow repositioning or removal of bubbles and wrinkles. If you find it difficult to get a smooth application you can use a hair dryer to soften the adhesive, then lift and reposition. Another method is to VERY LIGHTLY mist the application surface with a ammonia-based liquid glass cleaner before applying the label. This is only recommended if the label is very large, the adhesive is aggressive and/or the surface irregular. Use a label squeegee to ensure good contact with the surface. Finally, with firm pressure moving across the label to the edges to exclude air from behind the adhesive. Repeat this process two or three times to insure 100% adhesive contact to the surface. It is important that the adhesive “flow” or “wet-out” flowing into all the surface cracks and crevices. Adhesives will achieve maximum adhesion within 24 - 48 hours post application. During this period the label should be kept at the recommended application temperature. |
