The Aggressive White Matte (AT) has a very strong adhesive and is recommended for cardboard surfaces. There is a wide range of factors that can contribute to how well a label adheres to the surface it’s being applied to so we’ve included some recommendations below. -It’s important to ensure that the surface is clean and free of any debris, dust or moisture before attempting to apply your label. -Applying the center of the label first, and then continuing to apply pressure outward will ensure a nice, even application that should promote better adhesion. -Be careful when handling the label before application. Oil from your fingers can negatively affect the strength of the adhesive - try to hold the labels by the edge and touch the adhesive as little as possible. -Remember, our labels are pressure sensitive, so be sure to use some force when applying them to your surface or container. If you’ve followed the suggestions listed above and are still experiencing issues please feel free to send us a support ticket at the link below with details on the surface and method of application.
