Alkatuff LL438 is a high performance hexene linear low density polyethylene copolymer designed for a variety of applications requiring enhanced sealing characteristics and toughness. Alkatuff LL438 is formulated with process aid and a process stabilisation package but contains no slip or antiblocking additives

Film Extrusion: Alkatuff LL438 is intended for applications that require enhanced sealing performance, such as lamination and form, fill and seal films. Excellent toughness also makes Alkatuff LL438 ideal for heavy duty and low temperature applications. Addition of a UV stabiliser should be considered where the intended application involves intermittent to extended exposure to sunlight.
