| DINALEN® 55 is low density polyethylene containing slip and anti-blocking additives. It is primarily intended for blow and cast film extrusion while other processing techniques can be used to a lesser extent. DINALEN® 55 exhibits very good draw-down with good balance of stiffness, mechanical and optical properties of extruded film. DINALEN® 55 is extruded at recommended melt temperature range between 160°C and 180°C. Recommended film thickness: 0.25 to 0.05mm. Application Thin slippery film of high gloss and transparency Production of film for lamination Production of film for a variety of primary flexible packaging like FFS for foodstuffs, sanitary articles, chemicals Film production for a many kinds of carrier-bags, like airport security bags, DTK bags, cooler-bags, T-shirt-bags, shoulder-bags Blending with DINALEN 50 to obtain a less slippery film Mixing and co-extrusion with suitable i-polybutene-1 grades to produce film for peel systems Mixing and co-extrusion with suitable polyolefin grades&& |
