Polykar, a North American leader in the manufacturing of sustainable flexible packaging, purchased a complete extrusion line from Reifenhauser Polyrema that will be dedicated to make biopolymer films.

Operating out of its state-of-the-art plant in Montreal, Canada, Polykar has been making compostable films and bags for organic waste collection since 2009. This recent purchase will double its capacity for certified compostable bags to meet growing customer demand.

“Reifenhauser Polyrema has a long history in making extrusion lines that can effectively run various types of biopolymers. This expertise, the well-known reliability of their equipment and the ability to provide a customized solution for our facility made Reifenhauser the most viable partner,” explais Amir Karim, Polykar president and CEO.

Blown Film Extrusion Line for Biopolymers

The new line will be equipped with Reifenhauser’s EVO Ultra Range extruders designed to process all types of biopolymers in addition to the full range of traditional polymers. The EVO Ultra die provides advanced mechanical properties and higher tolerances with an overall lower pressure. The special thermo-element helps to eliminate over-heating of the melt entering the die center.

Reifenhäuser Polyrema worked closely with Polykar to custom fit the line into a location with space limitations and utilize Polykar’s existing tower structure with minimal changes.

    Newly available cast sheet and thermoforming grades of Mirel biobased polymers open up a new range of applications in containers and other formed parts where renewable content and biodegradability are desired.

  • Compounding PLA on Twin-Screws: What Testing Reveals

    Twin-screw extrusion is the preferred method for compounding PLA and other biopolymers. But processing PLA is complicated because it’s sensitive to heat and shear. It’s also prone to hydrolytic degradation if moisture is present in molten PLA. Here’s what one machine builder’s trials revealed.

  • Injection Molding Biopolymers: How to Process Renewable Resins

    U.S. injection molders are still pretty green when it comes to processing the new crop of renewably sourced biopolymers. These biologically derived polymers made from PLA, PHA and starch-based resins are attracting growing market interest as materials with no ties to petrochemical-based thermoplastics.
