HM liner bags are made from high-density polyethylene (HDPE) with a high molecular weight, which gives them remarkable tensile strength. This strength allows them to withstand heavy loads and rough handling without tearing, stretching, or puncturing. In long-term storage, where stability over time is critical, this strength ensures that the bags retain their integrity. These bags offer excellent moisture resistance, which is crucial for long-term storage of items sensitive to water, such as food, electronics, textiles, and chemicals. They create a reliable barrier that prevents moisture from entering and damaging the contents, which is essential for keeping items dry and in good condition over extended periods.
