Effect of LDPE Content on Properties of LLDPE/LDPE Blend

Linear low density polyethylene(LLDPE)/low density polyethylene(LDPE)blend film was prepared through melt blowing by Brabender extruder.The crystallization behavior and crystal morphology of the blend were characterized byDSC and POM.In addition,mechanical properties and melt rheological properties of the blend film were investigated.The results indicate that the comprehensive mechanical properties of the blend film can still keep fine after adding appropriateamount LDPE.The crystallinity and grain size of the blend decrease and melt rheological properties are improved with the increase of LDPE.
