60gsm - 100gsm Virgin Brown Kraft Paper for Valve Bags 20kg 25kg

Key Features and Characteristics:

High Strength and Burst Resistance:

• • Can hold heavy weight, such as 25kg, 50kg, and the significant impact and static pressure generated during handling, dropping, and stacking.
  • It possesses high tensile strength and tear resistance, ensuring the bag does not easily rupture when filled and lifted.

High Elongation and Toughness (Extensibility):

• Modern heavy-duty paper strongly emphasizes "extensibility," meaning the paper can undergo a certain degree of elastic elongation under force to absorb impact energy.

Good Breathability:

• • Appropriate breathability ensures smooth and safe filling.
  • breathability cannot be too high to prevent dust leakage.
