Details

A packaging manufacturer has developed a new rollstock format incorporating an active oxygen scavenging compound for use in vertical pouch packaging.  For the first time this enables products which are susceptable to oxygen such as avocado, tomatoes and fruit pulps to be packaged in vertical pouch packaging as the oxygen scavenging feature extends the product shelf life and makes it commercially viable to offer these vulnerable products for sale.
 
The resulting film is an active barrier oxygen scavenging film that removes any oxygen inside the pack or that migrates from outside of the packaging. Furthermore, the utilization of polymer film rather than metalized polyester also ensures there are no flex cracks, which otherwise allow oxygen ingress in to degrade the product.
 
The overall effect of blocking oxygen from the product results in maximized product flavor, colour retention, longer production runs and better inventory control for foodservice operations.
 
The film is marketed under the Cryovac®Freshness plus brand by the Sealed air company.

Potential Benefits

This product facilitates longer shelf life for delicate products which had previously been uncommercial to pack and distribute as wastage rates would be too high.  The added shelf life not only decreases food waste but enables consumers to be offered greated choice.

Intellectual Property

The new film is registered as the CryovacFreshness plus® brand by the Sealed air company.

Consultant View

This is another good example of active packaging being used to increase the shelf life of food products.  Not only does this help to reduce food waste but it also enables consumers to enjoy a wider range of products. Producers are also able to offer their products to a wider marketplace given the extended shelf life of the packed goods.
 
Other technologies also offering shelf life extension potential include improved barrier materials and antimicrobial packaging materials. Reviewers interested in this subject should search both the REID database and the wider Internet using terms such as "active packaging"; "antimicrobial", "oxygen scavenging" and "barrier" to identify other relevant technologies.
