Invera Flexibles Invests in Retrofit Technology from W&H

Modernizing Blown Film Production for Greater Performance.

Two Invera Flexibles production facilities in Quebec, Canada, are investing in the future of blown film production through a retrofit project designed to increase output, improve film
quality, and address equipment obsolescence.

The project encompasses two three-layer blown film extrusion lines installed in 2011 and 2014, serving plants in Laval and Montreal. By combining targeted equipment upgrades with the latest automation technology from Windmöller & Hölscher (W&H), the retrofit aims to extend machine life while delivering measurable improvements in production performance and reliability.

“Our customers count on us for consistent film quality, reliable supply, and the ability to support their growth,” said Amir Karim, CEO of Invera Flexibles. “This investment is designed to strengthen all three. By pairing our extrusion expertise with advanced technology from W&H, we are expanding the capabilities of our existing assets and reinforcing our commitment to being a long-term partner to our customers.”

The scope includes replacing obsolete electrical components, including drives and programmable logic controllers (PLCs), alongside upgrades to key extrusion components. These include a new automated ARCTIS II air ring, die, and air blowers, as well as new extruder components. The addition of Easy2 Run, W&H’s latest automation feature, further enhances the lines’ operational capabilities.

The expected benefits span quality, productivity, and reliability. Improved profile control and film flatness are anticipated to deliver higher-quality film, supporting consistent production and demanding customer requirements.

Output improvements are also projected to be significant. Depending on the application and operating conditions, production increases of approximately 15% to 24% are
estimated for linear low-density polyethylene (LLDPE) and low-density polyethylene (LDPE) recipes. For high- density polyethylene (HDPE) recipes, output gains of approximately 30% or more are projected, depending on the application and
operating conditions.

Replacing discontinued components and upgrading critical machine systems will also help improve reliability and reduce obsolescence-related risks.

Together, these upgrades demonstrate how strategic retrofits can unlock additional capacity, strengthen production reliability, and extend the useful life of existing blown film assets, helping Invera meet evolving customer requirements and support
future growth.
