Cortec’s Extrusion Capabilities

The first step in manufacturing is the extrusion process, where raw resin is transformed into film. Our blown film extrusion lines can produce flat tubing, gusseted tubing, single-wound sheeting, J-sheeting, centerfold, and other configurations. We can add color concentrates, VpCI ®, and other specialized additives such as static dissipatives, flame retardant, and ultraviolet inhibitors to exactly match your individual needs. We are capable of extruding linear low blends up to 100%. Sizes range from a 3” (76 mm) minimum lay-flat width up to a 30’ (9 m) maximum width depending on film configuration and film thickness.
