There are special considerations for storing and applying PVC (Polyvinyl Chloride) sticker labels to ensure their proper performance and longevity. Here are some important factors to keep in mind:
Storing PVC Sticker Labels:
Temperature and Humidity: Store PVC labels
in a controlled environment with stable temperature and humidity levels. Extreme temperatures, high humidity, or fluctuations in these conditions can affect the adhesive and label material. Ideally, store labels in a cool, dry place.
Protection from UV Exposure: Avoid storing PVC labels in direct sunlight or under UV lamps for extended periods, as excessive UV exposure can cause premature fading and degradation of label colors and materials.
Flat Storage: PVC labels should be stored flat to prevent warping or curling. Storing them on a flat surface, such as in labeled boxes or drawers, can help maintain their shape and adhesive quality.
Protection from Dust and Contaminants: Keep labels in sealed or protective packaging to prevent dust, dirt, and contaminants from adhering to the adhesive surface, which could affect the label's ability to adhere properly when applied.
Inventory Management: If you have a large quantity of PVC labels, practice good inventory management to ensure that older labels are used before newer ones. This helps prevent labels from becoming outdated or less adhesive-effective over time.
Applying PVC Sticker Labels:
Surface Preparation: Ensure that the surface where you plan to apply the PVC labels is clean, dry, and free from dust, oil, grease, and other contaminants. Cleaning the surface with a mild detergent or isopropyl alcohol can improve adhesion.
Temperature Considerations: The temperature of the label material and the surface being labeled can affect the adhesion process. It's generally recommended to apply labels at room temperature (around 70°F or 21°C). In colder conditions, warming both the labels and the surface can enhance adhesion. Conversely, in hot environments, avoid applying labels to surfaces that are too hot, as this can affect the adhesive.
Proper Alignment: Ensure accurate label placement and alignment. Using guides or marking the application area can help you position the labels correctly.
Apply Even Pressure: Apply even pressure across the entire label surface to ensure a secure bond. You can use a squeegee or a similar tool to press out any air bubbles or wrinkles during application.
Avoid Overlapping Edges: Avoid overlapping the edges of PVC labels, as this can lead to premature peeling or lifting.
Cure Time: Allow sufficient time for the adhesive to cure and bond with the surface before subjecting the labels to stress or exposure to moisture. The curing time can vary depending on the adhesive used and environmental conditions.
Label Care After Application: After applying PVC labels, avoid subjecting them to extreme stress or environmental conditions (e.g., excessive heat, moisture, or abrasion) for the recommended curing period to ensure proper adhesion.
By following these storage and application guidelines, you can help ensure that PVC sticker labels adhere properly, look their best, and maintain their performance throughout their intended lifespan. Proper surface preparation and care during application are critical to achieving a long-lasting bond between the label and the surface.
