Nova Chemicals (U.S. office in Moon Township, Penn.), and Mitsubishi Gas Chemical America (U.S. office in New York City), regarding their new flexible, shelf-extending packaging technologies. Both companies will showcase these technologies at Pack Expo Las Vegas, Sept. 25-27.  Here’s the scoop:

● Nova Chemicals has developed two easily recyclable flexible packaging film structures: one that is based on a moisture barrier formulation for such dry foods and mixes, frozen fruit,and confectionary; and, one with both a moisture and oxygen barrier formulation for nut mixes, granola bars, meats and cheeses and other snack foods that have traditionally required rigid or nun-recyclable mixed-material packaging. These resin formulations, including LLDPE and HDPE, are based on Nova’s dual-reactor Advanced Sclairtech Technology which produces a broad range of single-site catalyzed octane copolymers. Both base recipes are certified to carry the “In store drop-off” package label from How2Recycle, a rapidly growing program to help consumers understand end-of-life recycling options. Also, the designs are compatible with the #2 HDPE recycling stream.

The new structure designs can be used in a wide variety of package formats, including the popular and fast-growing stand-up pouch, pillow pouch, and flow wrapper. Also, packages can be customized for single-serve or multi-use through addition of zippers or fitments. Processors and converters can work with Nova’s experts at its Centre for Performance Applications to collaborate on film structures for the specific applications. The Centre recently completed installation of its new Effytec horizontal fill seal (HFFS) pouch maker, which will allow creation of prototype packages that can be tested on-site.  

● MGC has developed a technology that potentially doubles shelf life for organic and natural foods. Embedded as a film layer in either LLDPE or PP retort packaging applications, it removes oxygen from within sealed bags and pouches. The technology is based on MGC’s oxygen-scavenging Ageless OMAC technology which is made by compounding an iron powder as the active ingredient and is sandwiched between a barrier layer and a sealant layer. The technology is now available as a resin to North American film producers and converters, and can efficiently run on legacy processing systems.

The embedded film layer has been shown to extend and protect food’s natural characteristics without sachets, added spices or sodium. It is said to be ideally suited for soups, sauces, processed fruit, dips, protein bars, prepared meals and wet pet foods, which are particularly vulnerable to food spoilage. Mitsubishi will provide resin samples to film processors and converters to test run the technology.
