As a seasoned supplier of blister white cardboard, I've witnessed firsthand the challenges that come with preventing this versatile material from deforming. Blister white cardboard is widely used in various industries, from packaging to display, due to its excellent printability, stiffness, and cost - effectiveness. However, deformation can significantly impact its functionality and aesthetic appeal. In this blog, I'll share some practical tips and scientific insights on how to prevent blister white cardboard from deforming.


Understanding the Causes of Deformation
Before we delve into prevention strategies, it's crucial to understand what causes blister white cardboard to deform. There are several factors at play, including environmental conditions, handling, and storage.
Environmental Conditions
Humidity is one of the most common culprits. Blister white cardboard is hygroscopic, meaning it absorbs and releases moisture depending on the relative humidity of the surrounding environment. When the cardboard absorbs too much moisture, it can become soft and lose its shape. On the other hand, in low - humidity conditions, the cardboard may dry out and become brittle, leading to cracking and warping.
Temperature also plays a role. Extreme heat can cause the cardboard to expand and lose its structural integrity, while cold temperatures can make it more prone to cracking.
Handling
Improper handling during transportation and assembly can lead to deformation. Rough handling, such as dropping or crushing the cardboard, can cause dents, creases, and bends. Additionally, if the cardboard is not cut or folded correctly, it may not fit together properly, resulting in an uneven or deformed final product.
Storage
Storing blister white cardboard in an inappropriate manner can also contribute to deformation. Stacking the cardboard too high or unevenly can put pressure on the lower layers, causing them to warp. Exposure to direct sunlight or other heat sources during storage can also cause the cardboard to deform.
Prevention Strategies
Control the Environment
- Humidity Management: Maintaining a stable humidity level is essential. Aim for a relative humidity of around 40% - 60% in the storage and working areas. You can use dehumidifiers or humidifiers to achieve this. For example, in a warehouse with high humidity, a dehumidifier can remove excess moisture from the air, preventing the cardboard from absorbing it.
- Temperature Control: Keep the temperature in the storage and working areas within a reasonable range, typically between 18°C - 24°C. Avoid storing the cardboard near heaters, radiators, or other heat - generating equipment. If the temperature is too high, use air - conditioning to cool the space.
Proper Handling
- Gentle Handling: Train your staff on proper handling techniques. Encourage them to lift and move the cardboard carefully, avoiding dropping or throwing it. Use appropriate equipment, such as forklifts or pallet jacks, to move large stacks of cardboard.
- Precision Cutting and Folding: Invest in high - quality cutting and folding equipment to ensure accurate and clean cuts. Use templates or guides to ensure that the cardboard is cut and folded at the correct angles and dimensions. This will help the cardboard fit together properly and reduce the risk of deformation.
Correct Storage
- Proper Stacking: Stack the blister white cardboard evenly and avoid over - stacking. Use pallets or racks to support the cardboard and distribute the weight evenly. Make sure the stacks are stable and do not lean or tip over.
- Protection from Light and Heat: Store the cardboard in a dark, cool place away from direct sunlight. If possible, cover the stacks with a protective sheet to shield them from light and dust.
Product - Specific Considerations
Quality of the Cardboard
The quality of the blister white cardboard itself can also affect its resistance to deformation. When selecting a supplier, look for high - quality products. For instance, our Blister White Cardboard Sheet is made from premium materials and undergoes strict quality control measures. It has excellent stiffness and durability, making it less prone to deformation.
Thickness and Density
Thicker and denser cardboard generally has better resistance to deformation. Our High Stiffness 300GramWhite Blister Packing Paper For Blister Package is a great example. With a higher gram weight, it offers enhanced stiffness and can withstand more pressure without deforming.
Coating
Some blister white cardboard is coated on one or both sides. A coating can provide additional protection against moisture and improve the cardboard's resistance to deformation. Our White Blister Packaging Paper Card 300gsm One Side Coated Paperboard has a special coating that not only enhances its appearance but also makes it more resistant to environmental factors.
Conclusion
Preventing blister white cardboard from deforming requires a combination of environmental control, proper handling, correct storage, and the selection of high - quality products. By following the strategies outlined in this blog, you can ensure that your blister white cardboard maintains its shape and functionality, resulting in a better - quality final product.
