Several polyethylene grades are used to manufacture PE Film, with LDPE (Low-Density Polyethylene), LLDPE (Linear Low-Density Polyethylene), and HDPE (High-Density Polyethylene) being among the most common. Each material provides different characteristics, allowing manufacturers to select the appropriate resin according to the intended application. LDPE Film is known for its flexibility, softness, transparency, and excellent heat-sealing characteristics. It is widely used for packaging bags, liners, shrink applications, agricultural films, and protective packaging where flexibility is important. LDPE Film generally offers a strong combination of tensile strength, puncture resistance, elongation, and flexibility. It is commonly used for stretch film, industrial packaging, heavy-duty bags, agricultural films, and applications where high mechanical performance is required. Its excellent toughness allows manufacturers to produce thinner films without necessarily sacrificing required performance. HDPE Film has greater stiffness and tensile strength compared with LDPE, while typically providing a more opaque or translucent appearance. It is suitable for applications requiring strength, dimensional stability, and resistance to puncture or tearing.
