Each roll is wound on a 76 mm (3-inch) inner diameter paper core, fully wrapped in stretch film, stacked vertically or horizontally on pallets and re-wrapped with stretch film. Every roll carries a label listing specs, item code, roll weight, width, serial number and production date for full traceability; each pallet is also labeled with full traceability data.

For optimal performance, store fiberglass materials in cool, dry warehouses at 15℃–35℃ and 35%–65% RH. Keep away from heat and water to prevent damage and contamination. Use rolls promptly after unpacking. Repack unused material tightly and avoid open-air exposure to preserve shelf life.
