is a concentrate of high molecular weight Polyisobutylene tackifier in linear low-density polyethylene. It is used as a cling agent to make stretch wrap films from LLDPE or LOPE. It is a dry free-flowing pelle
is designed to produce a stretch film from LLDPE, LOPE, or other polyolefins for the applications of pallet wrap, silage wrap, and food wrap. It can be used in both blown or cast film process. Polymers used with Pure Polymers Cling MB must not contain any slip or antiblock additives or have a density higher than 0.923 as this will prevent the migration of the cling additive. Migration time for good cling properties fs 72-24 hours.
For monolayer blown films 8% by weight should be added to LLDPE (or resin mix).
For monolayer cast films 3 and 4%.
On multilayer film lines, is often added to the skin layers only. Addition rate depends on which layer is used and the layer thickness.
Pure Polymers Cling MB masterbatch range is based on Polyisobutylene technology and It can be used in both blown and cast film processes with mono & multi-layers structures. It delivers cling strengths such as Peel cling Strength, Lap cling Strength, or Retack ability.
