High-Density Polyethylene (HDPE) bags are stronger, more rigid alternatives to LDPE bags. They offer improved puncture resistance and lower moisture permeability, making them suitable for heavier or more abrasive products such as granulated chemicals, bulk drugs, and metal powders.
HDPE bags are often used where a higher level of durability is required during handling or transport. They are also commonly employed as drum liners or overwraps in industrial packaging.
