The W&H Varex extrusion line is a well-known solution in the field of blown film production and has built a strong reputation for reliability, flexibility, and performance. Manufactured by Windmöller & Hölscher (W&H), one of the leading companies in the packaging machinery industry, the Varex line has been used worldwide by film producers who demand consistent quality and efficiency. W&H has a long history of innovation in extrusion technology, with a focus on advanced process control, precise film properties, and energy efficiency.
This particular extrusion line is designed as a 3-layer system, which allows for the production of multilayer films with different barrier and strength properties. Multilayer extrusion is widely used in packaging applications to combine features such as durability, printability, and product protection. With a working width of 1600 mm, the line is suitable for a broad range of film formats and production requirements. The output capacity of 280 kg per hour provides a balance between productivity and flexibility, making it a reliable choice for medium- to large-scale operations.
An important feature of this line is that the control system was renewed by W&H in 2019. Modern controls improve not only ease of use but also process stability, automation, and integration with other systems. This update ensures that the line continues to meet today’s standards in efficiency and operation. Overall, the W&H Varex extrusion line remains a proven and versatile machine for high-quality film production in the flexible packaging industry.
