The technical specifications of packaging paper directly affect its protective performance and durability. Tensile strength (typically ≥3.0 kN/m) determines the paper's ability to resist stretching, ensuring it is not easily torn during transportation; bursting strength (≥400 kPa) reflects its compressive strength, effectively preventing damage caused by heavy impacts; tear strength (≥600 mN longitudinally, ≥500 mN transversely) ensures the integrity of the packaging under friction from sharp objects; folding endurance (≥50 times) reflects its durability after repeated folding, suitable for packaging scenarios requiring multiple folds. These parameters together ensure that packaging paper effectively protects goods during logistics, warehousing, and other processes.
Water/Oil Resistance: Food packaging paper must possess water barrier properties and comply with food safety standards such as GB 4806.8.
Antibacterial/Mildew Resistance: Required for some food or medical packaging.
Breathability: Used for packaging tea, fruits, and vegetables that require breathability.
Printability: Recommended resolution ≥ 300 dpi, high-end products can reach 600 dpi.
