Instructions for Adhesive Bar Code Label Application and Storage

To ensure maximum performance of the pressure sensitive labels from storage through application, we recommend the following procedures:

Storage

Labels should be stored at 72°F (22°C) and 50% relative humidity. Storing labels at higher or lower temperatures may not provide the level of adhering performance you desire.

Surface Preparation

The surface the label stock will be applied to must be dry, dust free, and cleaned of all oil, grease and oxidized materials. Surfaces may be cleaned with an industrial cleaning solution (which your organization may already be using), or Isopropyl Alcohol (rubbing alcohol). Stronger solvents are required to remove process oils from bare materials. It is important to check the durability of the surface to be cleaned in an unseen area or on the backside with available solvent before cleaning in label area. Wipe dry with clean rags or absorbent paper towels. Commercial re-washed shop towels are not recommended.

Application

The label stock should be allowed to condition at room temperature (70°F to 100°F) before application is attempted. The surface must be at least 50°F. Below this temperature the adhesive becomes too firm to adhere readily.

Remove the liner from the label stock being careful not to touch the adhesive with your fingers. Do not allow the adhesive to become contaminated with dust or dirt.

For thin labels (.005″ and thinner):
Apply the label stock to the surface with firm thumb pressure starting from one side of the label and moving across the label to the opposite side to exclude air from behind the adhesive. When using a roller, select the softest roller possible and do not use excessive pressure. Using firm pressure, repeat the process two or three times to insure 100% contact of the adhesive to the surface. In this situation, “more is better”. More application contact provides a higher immediate bond. This allows the adhesive to “flow” into the cracks and crevices of a substrate thereby achieving more intimate contact between the adhesive and the surface.

For .012″ and thicker labels:
Apply the label stock to the surface with a rolling motion to exclude air from behind the adhesive. Use a soft roller or a clean cloth to firmly press the label stock down to insure 100% contact of the adhesive to the surface. In this situation, “more is better”. More roll down provides higher immediate bond. This allows the adhesive to “flow” into the cracks and crevices of a substrate thereby achieving more intimate contact between the adhesive and the surface.

Adhesives will meet maximum holding power after 72 hours.

We cannot anticipate all of the different surfaces and contaminants that may exist. We recommend that the user conduct a test of surface preparation and label adhesion before ordering labels or adhering thousands of production labels. In addition, when there are changes in plastics, on paint formulations or supplies of these materials, it is advisable to run another evaluation.
