What is LLDPE Film?
LLDPE (Linear Low-Density Polyethylene) film is a type of polyethylene with a semi-linear structure and short branched chains, produced by copolymerizing ethylene with alpha-olefins such as butene and hexene. This film strikes an ideal balance between high flexibility, mechanical durability, and puncture resistance. With the capability of being produced in thinner gauges compared to LDPE, it is considered a more economical and environmentally friendly choice for packaging.
Among the prominent advantages of LLDPE film are its high tensile strength (around 45 MPa), an exceptional elongation ratio (up to 600–800%) during blown film processing, and its resistance to impact and puncturing. Its acceptable transparency, low-temperature toughness, and suitability for various applications—including food packaging, agriculture, industrial use, and stretch films—have helped this film secure an important position in the category of versatile films.
