nonwoven storage guide

  Dear Valued Customers and Partners, did you know that proper storage is a critical factor in preserving the superior performance of our polypropylene (PP) spunbond nonwoven fabric?    Incorrect storage conditions can lead to product aging, reduced fabric strength, or even render the material unusable, ultimately disrupting your production process and final product quality. To help you maximize the potential of our high-quality non-woven products, we have prepared this detailed scientific storage guide.   Core Storage Principles:   1. Palletize and Keep Off the Ground   Use Pallets: Always place all rolls or sheets on sturdy, flat wooden or plastic pallets. This not only prevents packaging damage but also effectively isolates moisture from the floor.   No Direct Ground Contact: Never stack products directly on the ground, as even concrete floors can become damp under certain conditions, posing a latent threat to the non-woven fabric.   2. Provide an Ideal Indoor Environment   Control Temperature & Humidity: The warehouse or storage room should be kept cool and dry. We recommend an ambient temperature between 15°C - 30°C and a relative humidity of 50% - 65%.   Ensure Good Ventilation: Maintain adequate air circulation to prevent stuffiness and moisture buildup. Ensure that vents do not introduce external dust.   3. Protect from UV Light and Heat   Avoid Sunlight/UV Rays: Ultraviolet (UV) light is the primary cause of polypropylene degradation. It is essential to store nonwoven fabric in a location completely shielded from direct sunlight. Windows should be covered with blackout curtains or UV-blocking film.   Keep Away from Heat Sources: Store products away from any heat sources such as radiators, boilers, or heaters, as sustained high temperatures can cause material deformation or performance degradation.   4. Follow Stacking Guidelines   Limit Stacking Height: Adhere to the maximum number of stacking layers indicated on the packaging. Over-stacking can exert excessive pressure on the bottom rolls, causing permanent deformation and issues in subsequent processing.   Practice FIFO (First-In, First-Out): Establish and strictly follow a FIFO inventory management system. This ensures that the oldest stock is used first, preventing natural aging due to prolonged storage.   Conclusion: By following these simple storage principles, you can significantly extend the service life of your PP spunbonded nonwoven fabric, and ensure its consistent performance.   Proper storage is not only a protection for the product but also a safeguard for your production efficiency.
