All W&H OPTIMEX and VAREX blown film lines in 3- to 9-layer configurations have been awarded the energy efficiency certificate from TÜV Süd.

Due to the difficulty of comparing data on different lines, previous studies focused on individual components of a blown film line. This is the first time a complete series of blown film extrusion lines has been audited on its energy consumption and been awarded the "best available technology" in energy efficiency by TÜV Süd. The VISTAFLEX and MIRAFLEX flexographic presses have been also been awarded TÜV certificates. TÜV Süd certification states that W & H machinery completely meets the energy efficiency requirements.
Sustainability has long been a topic of intense discussion in film extrusion; the main focus being reducing energy. Auditing blown film lines involved extensive measurements to determine energy consumption of the OPTIMEX and VAREX lines as well as to define a reasonable scope of the investigation. In a subsequent step, TÜV Süd examined the extent to which W&H strives for energy efficiency in both their corporate orientation and manufacturing processes.
As a market and technological leader, W&H views this certification as documented proof of its commitment to the design of energy-efficient blown film extrusion lines. This independent audit provides customers with the assurance that all components requiring electricity or compressed air on a W&H blown are equipped with the most up-to-date, cutting-edge technology.
This certification can be presented to national agencies as documented proof of energy efficiency of newly purchased W&H blown film lines. In Europe, such documentation is useful for obtaining a certificate according to ISO 50001; the requirement is for the partial exemption from the Renewable Energy Reallocation Charge and future relief of the electricity and energy tax to those companies in the manufacturing sector.
