Borstar FB4250T Borealis Polyethylene, Linear Low Density

Product Description

Borstar FB4250T is a high molecular weight linear low density polyethylene grade combining good extrusion properties, excellent draw down properties and good mechanical strength. Film made from Borstar FB4250T exhibits a good balance between dart impact combined with excellent yield and tensile strength and improved stiffness. Its toughness also remains in cold climate conditions. The film has good seal strength, wide sealing window and good hot tack force. In addition to the well know Borstar properties,

Borstar FB4250T also give good optical properties
