As a supplier of PU Domed Logo Decals, I understand the importance of proper storage for these high - quality products. Whether you're a business that has ordered a large batch of decals for future use or an individual with some leftover decals, improper storage can lead to a range of issues, from reduced adhesive strength to physical damage. In this blog, I'll share some effective ways to store unused PU Domed Logo Decals properly.
Understanding the Nature of PU Domed Logo Decals
Before delving into storage methods, it's crucial to understand what PU Domed Logo Decals are. PU Domed Logo Decals are made of polyurethane resin, which forms a dome - shaped layer over a printed logo or design. The polyurethane layer gives the decals a glossy, three - dimensional appearance and provides protection to the underlying print. The back of these decals usually has an adhesive layer, which allows them to be attached to various surfaces.
The polyurethane resin is sensitive to environmental factors such as temperature, humidity, and light. Extreme conditions can cause the resin to deform, lose its shine, or even crack. The adhesive can also be affected, leading to reduced sticking power when it's time to use the decals.
Temperature and Humidity Control
One of the most important aspects of storing PU Domed Logo Decals is controlling the temperature and humidity of the storage environment.
Optimal Temperature Range: The ideal temperature for storing PU Domed Logo Decals is between 18°C and 25°C (64°F - 77°F). Temperatures outside this range can cause problems. If the temperature is too high, the polyurethane resin may soften, causing the dome to lose its shape. High temperatures can also accelerate the aging process of the adhesive, reducing its effectiveness. On the other hand, if the temperature is too low, the resin may become brittle and crack, and the adhesive may lose its flexibility.
Humidity Considerations: Humidity should be kept at a moderate level, around 40% - 60%. High humidity can cause moisture to be absorbed by the decals, which may lead to the growth of mold or mildew, especially if the decals are stored in a sealed container. Low humidity, on the other hand, can cause the polyurethane to dry out and crack.
To maintain the proper temperature and humidity, you can store the decals in a climate - controlled room. If this is not possible, you can use a dehumidifier or a humidifier in the storage area, depending on the local climate conditions.
Protection from Light
Exposure to direct sunlight or strong artificial light can have a negative impact on PU Domed Logo Decals. Ultraviolet (UV) rays in sunlight can cause the polyurethane resin to yellow and fade over time. The colors of the printed logo or design may also be affected, leading to a less vibrant appearance.
To protect the decals from light, store them in a dark place. You can use opaque storage containers or boxes. If the decals are stored on shelves, make sure the shelves are in a shaded area or use curtains to block out light.
Proper Packaging
The way you package the decals also plays a significant role in their storage.
Original Packaging: If the decals come with original packaging, it's best to keep them in it. The original packaging is usually designed to provide some level of protection during shipping and short - term storage. However, if you need to store the decals for a long time, you may need to consider additional protection.
Separate Sheets: When storing multiple decals, it's important to keep them separated. If the decals are stacked directly on top of each other, the adhesive on one decal may stick to the dome of another, causing damage when you try to separate them. You can use sheets of wax paper or parchment paper between each decal to prevent sticking.
Sealed Containers: Place the decals in a sealed plastic container or a ziplock bag. This helps to protect them from dust, moisture, and other contaminants. Make sure to remove as much air as possible from the container or bag before sealing it.
Avoiding Physical Damage
During storage, it's important to avoid physical damage to the decals.
Flat Storage: Store the decals flat to prevent the dome from being deformed. If the decals are rolled or bent, the polyurethane resin may crack or lose its shape. You can use a flat storage box or a drawer to keep the decals in a flat position.
Avoid Pressure: Do not place heavy objects on top of the decals. Pressure can cause the dome to flatten or the adhesive to spread unevenly. If you need to stack storage containers, make sure the decal containers are on top or in a position where they won't be crushed.
Special Considerations for Different Types of PU Domed Logo Decals
There are different types of PU Domed Logo Decals, such as Die Cutting 3M Adhesive PU Resin Stickers and Clear Polyurethane Coated Dome Labels. Each type may have some special storage requirements.
Die Cutting 3M Adhesive PU Resin Stickers: These stickers have a precise die - cut shape, which makes them more vulnerable to physical damage. When storing them, pay extra attention to keeping them flat and avoiding any sharp objects that could cut or damage the edges. The 3M adhesive is known for its high - quality, but it can still be affected by temperature and humidity, so follow the general storage guidelines mentioned above.
Clear Polyurethane Coated Dome Labels: The clear coating on these labels is particularly sensitive to scratches and abrasions. When storing them, use a soft, non - abrasive material to separate the labels. You may also want to use a padded storage container to provide extra protection.
Long - Term Storage Tips
If you need to store the PU Domed Logo Decals for an extended period, here are some additional tips:
Regular Inspection: Check the decals periodically, at least once every few months. Look for any signs of damage, such as cracks, discoloration, or reduced adhesive strength. If you notice any problems, take appropriate action, such as adjusting the storage conditions or using the decals before they become unusable.
Documentation: Keep a record of the storage conditions, including temperature, humidity, and the date of storage. This can help you troubleshoot any issues that may arise and ensure that the decals are stored under optimal conditions.
Conclusion
Proper storage of unused PU Domed Logo Decals is essential to maintain their quality and performance. By controlling the temperature and humidity, protecting them from light, using proper packaging, and avoiding physical damage, you can ensure that the decals remain in good condition for a long time.
