Benefits of Coextruded LLDPE / LDPE Film vs. Blended LLDPE / LDPE Film, 1999 Polymers, Laminations & Coatings Conference Proceedings

Joe Taylor, Jae Jin Baik--The benefits of three-layer coextrusion versus a mono-layer blend of the same resins are explored. Good design considerations of the coextruded structure can allow a processor to take advantage of the performance characteristics of the resins and the equipment. These performance characteristics can be compromised in a mono-layer blend of the same materials. Expected benefits of coextrusion can be improved physical properties and reduction in additives required for good processing. These are accomplished by eliminating blends of LDPE and LLDPE, reducing the draw-down ratio and taking advantage of the rheological differences between LDPE and LLDPE.
