1. Introduction #
Adhesive labels are widely used in various industries for identification, instruction, and branding purposes. The effectiveness and longevity of these labels are influenced by the correct application methods. The application process involves numerous factors, such as label material, the adhesive surface on the back of the label, the material of the target surface, and environmental conditions.
2. Pre-application Preparations #
2.1 Cleaning the Application Surface #
The surface to which the label is applied must be free from oil, dust, and moisture. These contaminants can affect the adhesive strength of the label and hinder its ability to adhere effectively.
2.2 Choosing the Appropriate Label #
Selecting a label suitable for the specific item and environment is crucial. For example, labels to be used in low-temperature conditions should have appropriate temperature tolerance, and labels intended for rough surfaces might require a stronger adhesive.
2.3 Test Application #
Conducting a test application before large-scale labeling helps to confirm the adhesive strength and adherence of the label to the intended surface.
3. Application Process #
3.1 Positioning #
The application position of the label should be determined based on the specific needs. If precise positioning is necessary, markings on the surface can be done before applying the label.
3.2 Peeling Off the Backing #
The label’s backing needs to be carefully peeled off along the edge to avoid damaging the label.
3.3 Smooth Application #
Labels should be applied smoothly at the predetermined position to minimize bubbles and wrinkles. For larger labels, starting from one side and sliding towards the other can help reduce air bubble formation.
3.4 Pressing #
After application, an even pressure should be applied to the label to ensure it adheres more closely to the surface. This can be done with hands or a hard object.
4. Precautions #
4.1 Temperature Influence #
Environmental temperature can affect the stickiness of the label. The adhesive surface of the label may lose its stickiness in overly cold or hot conditions. It’s essential to ensure that the environmental temperature is within the label’s tolerance range.
4.2 Time Factor #
The adhesive strength of most labels increases over time, meaning the label’s adherence will gradually improve after application.
4.3 Avoid Touching the Adhesive Surface #
During application, direct contact with the label’s adhesive surface should be minimized to maintain its stickiness and adherence.
4.4 Storage Conditions #
Unused adhesive labels should be stored under optimal conditions – in a dry, light-protected, and normal temperature environment. Avoiding direct sunlight and humid environments helps to maintain the label’s stickiness and print effect.
