Packing parameters are carefully engineered based on extensive international shipping experience and standard logistics requirements. The number of sheets per pack and volume of each unit are balanced to ensure efficient use of cargo space, load stability during transportation, and compliance with standard weight limitations. Sheet count per pack is adjusted according to thickness, which helps prevent overloading and ensures safe and convenient handling during loading, unloading, and multiple relocations.
