Sustainable resin in Sealed Air’s inflatable film

Cardia Bioplastics helped Sealed Air develop its innovative Fill-Air inflatable packaging, based on renewable and recycled content, plus reduced, re-used and re-cycled product.

As Cardia Bioplastics managing director Dr Frank Glatz explains, the main design goals were to reduce the need for petroleum-based resins and to maintain the packaging integrity of the Fill-Air protective void fill cushions.

“First, our Cardia Biohybrid resin enabled Sealed Air to reduce their dependency on non-renewable petroleum-based resins by 10% and the incorporation of 10% pre-consumer recycled content, meant that this new film reduced the need for petroleum-based resins by 20%, as compared with the Fill-Air Select and Ultra films,” he says. “The second aspect of Sealed Air’s performance standards presented a greater technical challenge. The Cardia Biohybrid resin had to meet precision performance standards during both the manufacture of the film and later at the point of use, when the film is inflated and used as void fill.”

At the point of use for Sealed Air customers, this sustainable film delivers robust performance in demanding conditions. It must provide high speed processing on the Sealed Air range of Fill-Air packaging systems and excellent sealability to ensure good air retention, while protecting the packaged goods in transit.

Cardia Biohybrid resins combine renewable thermoplastics with polyolefin material to reduce dependence on finite oil resources, and to reduce carbon footprint. The renewable material is derived from corn crop grown for industrial use that will be replenished in the next growing season.
