PIB-Masterbatch

PIB masterbatch-- stretch film machine INTRODUCTION ZN-2 is a concentrate of high molecular weight Polyisobutylene tackifier in Linear Low Density. It is used as a cling agent to make stretchwrap films from LLDPE or LDPE.The high PIB content achieves its excellent cling property.FEATURES appearance Lightly powdered opaque dry pellets %cling agent 60% density 0.902 moisture <0.5% USAGE ZN-2 is designed to produce stretchwrap films from LLDPE, LDPE orfor the applications of palletwrap and silagewrap. It can be used on either blown film or cast film process.Polymers used with ZN-2 masterbatch must not contain any Anti blocking additive, slip agent as this will prevent the migration of cling additive. Migration time for good cling properties is usually 24 to 72 hours. Note: during production, the speeder the film get cool,means stronger adhesion the film surface is; and the more ZN-2added in, the stronger adhesion get. Production thereafter, should keep the film in a high temperature to enhance the the adhesion as the storge time goes. RECOMMENDED ADDITION On monolayer blown film lines,6 to 8% ZN-2 by weight should be added to resin mix.On monolayer Cast lines ,3 to 4% ZN-2.On multiple-layer film lines, ZN-2 is usually added to the skin layers only. Addition level depends on which layer is used and the thickness of layer.PACKAGING & STORAGEPacked in 20kg/bag, 25kg/bag and 1000 kg/bag or be palletized. Keep the place dry with good ventilation.
