LLDPE 3518
LLDPE 3518 is a supreme-performance linear low density polyethylene resin celebrated for its unparalleled combination of optical transparency and extreme mechanical toughness. Boasting a versatile melt flow index of 3.5 g/10min, this premium grade delivers an extraordinary dart drop impact strength of 1000g alongside an immaculate, glass-like ultra-low haze profile of just 3% at 25µm thickness. Engineered with balanced biaxial Elmendorf tearing metrics (TD up to 400 gf/µm) and high tensile elongation capacities, it represents the definitive industrial standard for premium multi-layer stretch wraps, high-clarity surface protection films, electronics packaging, and heavy-duty shrink laminations requiring rigorous abuse resistance.
