Applications of Polyethylene Blends

PE films are usually produced by the blown film extmsion method. The alternative method is sheet extrusion followed by passing through chilled rollers. Blown film is more economic biaxial orientation is introduced by the draw-off and blow ratios. Bubble stability is critical to the blown film process. Bubble stabihty is provided by the melt strength and rheological characteristics of the PE. Long [Pg.65]

HDPE LDPE Toughened HDPE with improved processing, especially melt strength HDPE and LDPE are immiscible [Pg.65]

HOPE LLDPE (or LDPE) Pipe grade HDPE required rheology for extmsion rigidity and impact resistance for pipes [Pg.65]

LLDPE LDPE Typical film combination for increased melt strength, elasticity combined with LLDPE strength. These are the most widely used PE blends [Pg.65]

LLDPE mLLDPE or mVLDPE Packaging films with improved melting and flow character for heat seal [Pg.65]
