Sabic 118WJ is a butene linear low density polyethylene resin typically used for general‐purpose packaging. It is easy to process and has good tensile properties, impact strength and optical properties. So the films produced from this resin are tough with good puncture resistance, high tensile strength and good hottack properties.

The LLDPE 118WJ contains slip and antiblock additives. However, this LLDPE resin is not intended for and must not be used in any medical applications.

Main Applications of LLDPE 118WJ

Shipping sacks, ice bags, frozen food bags, stretch wrap film, produce bags, liners, carrier bags, garbage bags, agricultural films, laminated and coextruded films for meat wrap, frozen food and other food packaging, shrink film (for blending with LDPE), industrial consumer packaging, and high clarity film applications if blended with (10~20%) LDPE.
