As a supplier of 90gsm Sticky Sublimation Paper, I understand the importance of proper storage to prevent curling. Curling can significantly affect the usability of the paper, leading to misfeeds in printers and poor transfer quality in sublimation processes. In this blog, I'll share some scientific and practical ways to store 90gsm Sticky Sublimation Paper to keep it in the best condition.
Understanding the Causes of Curling
Before we delve into the storage methods, it's crucial to understand why the 90gsm Sticky Sublimation Paper curls. The primary reason is the imbalance of moisture content. Sublimation paper is hygroscopic, which means it can absorb and release moisture from the surrounding environment. When one side of the paper absorbs more moisture than the other, it expands, causing the paper to curl. Temperature changes can also exacerbate this problem. For example, if the paper is stored in a place with high humidity and then suddenly moved to a low - humidity area, the moisture will quickly evaporate from the paper, leading to curling.
Ideal Storage Conditions
Temperature
The ideal temperature for storing 90gsm Sticky Sublimation Paper is between 20°C - 25°C (68°F - 77°F). This temperature range helps to maintain a stable moisture level in the paper. Extreme temperatures can cause the paper to expand or contract unevenly. For instance, in a hot environment, the paper may dry out too quickly, leading to curling, while in a cold environment, the moisture in the paper may condense, also causing the paper to curl.
Humidity
Humidity is another critical factor. The relative humidity should be maintained between 40% - 60%. At this humidity level, the moisture content in the paper remains stable. If the humidity is too high, the paper will absorb excess moisture, becoming soft and prone to curling. On the other hand, if the humidity is too low, the paper will lose moisture rapidly, resulting in curling as well. You can use a hygrometer to monitor the humidity in the storage area. If the humidity is not within the ideal range, you can use a dehumidifier to reduce humidity or a humidifier to increase it.
Storage Containers and Methods
Sealed Plastic Bags
One of the simplest and most effective ways to store 90gsm Sticky Sublimation Paper is in sealed plastic bags. These bags can prevent the paper from coming into contact with the outside environment, thus reducing the risk of moisture absorption or loss. When placing the paper in the bag, make sure it is flat and not folded. You can also add a small packet of silica gel to the bag. Silica gel is a desiccant that can absorb excess moisture, helping to maintain a stable moisture level in the bag.
Cardboard Boxes
Cardboard boxes can also be used for storage. However, it's important to choose a high - quality cardboard box that is resistant to humidity. Line the box with a plastic sheet before placing the paper inside to provide an extra layer of protection. Stack the paper neatly in the box, and close the box tightly. Keep the box in a dry and cool place.
Vertical Storage
Storing the 90gsm Sticky Sublimation Paper vertically can also help prevent curling. When the paper is stored vertically, the weight is evenly distributed, reducing the pressure on the edges and corners of the paper. This can prevent the paper from curling due to uneven pressure. You can use a paper rack or a filing cabinet to store the paper vertically.
Additional Tips
Avoid Direct Sunlight
Direct sunlight can cause the paper to dry out quickly, leading to curling. Therefore, it's important to store the paper in a place away from direct sunlight. A storage room with opaque curtains or in a cabinet is a good choice.
Limit Exposure to Air
When you need to use the paper, try to limit its exposure to air. The longer the paper is exposed to air, the more likely it is to absorb or lose moisture. Take out only the amount of paper you need for immediate use and keep the rest properly stored.
Comparison with Other GSM Papers
We also offer 120gsm Sticky Sublimation Paper, 100gsm Sticky Sublimation Paper, and 80gsm Sticky Sublimation Paper. Generally, thicker papers like the 120gsm are less likely to curl compared to the 90gsm and 80gsm papers. However, the basic storage principles are the same for all these papers. They all need to be stored in a stable environment with proper temperature and humidity control.
Conclusion
Proper storage of 90gsm Sticky Sublimation Paper is essential to prevent curling and ensure its optimal performance. By maintaining the right temperature and humidity, using appropriate storage containers, and following the additional tips mentioned above, you can keep your paper in excellent condition.
