LL0209AA and LL0209KJ are linear copolymers of low-density polyethylene containing butene-1 as a comonomer. LL0209KJ offers a high-slip film with easy opening when used in pure form in the 35-100 micron thickness range. The addition of other polymers, masterbatches, and pigments, or the use of a different thickness, may affect the film's sliding and anti-adhesive properties.
