Proper storage of industrial paper rolls is crucial to preserving cellulose fiber strength, ensuring high-speed corrugating efficiency and box load durability.

1. Handling and Stacking Rules for Kraft Paper Rolls

To shield heavy paperboard rolls from physical damage and ambient moisture absorption, Tien Thanh A&E's warehouse operates under strict storage protocols:

• Vertical Stacking: Giant kraft paper rolls (weighing 1.5 to 2.5 tons) are stored vertically rather than horizontally. Vertical storage distributes the massive weight evenly along the inner core, preventing deformation and flat spots.

• Off-Floor Pallet Storage: Rolls are placed on heavy-duty acacia or pine wood pallets (ISPM-15 compliant), elevating them at least 20cm above the concrete warehouse floor to block capillary moisture rise.

• Wall Clearance: A minimum gap of 50cm is maintained between rolls and warehouse brick walls, ensuring proper airflow and preventing rainwater seepage contacts.

2. Environmental Controls: Humidity and Temperature (Warehouse HVAC)

Relative humidity (RH) is the primary threat to stored paperboard raw materials:

• Optimal Humidity Target: Indoor warehouse humidity is regulated between 50% and 65% RH, with temperature kept at 20 - 30°C.

• Smart IoT Environmental Sensors: Wireless sensors transmit atmospheric humidity statistics to our smart factory system. If moisture levels exceed 70% RH, automatic ventilation fans turn on to purge excess moisture, preventing paperboard mold growth.

• Pest and Vermin Control: Regular eco-friendly biological fumigation is conducted across the warehouse to eliminate rodents and termites that target cellulose fibers.

3. Rigorous Fire Prevention Standards (PCCC)

Paper is highly combustible, requiring Tien Thanh A&E to employ active fire safety measures:

• Automatic wet-pipe sprinkler systems cover the entire warehouse area.

• Thermal fire barriers separate the paper roll storage hangars from the active BHS corrugator production floors.
