The new pasta sauce pouches from Unilever are being marketed to consumers as more convenient than their glass jar predecessors. Yet, if you consider the energy required to produce, fill, seal, label, pack and transport the pouches its evident there is a huge sustainability play at work here. The energy needed to produce glass jars, metal vacuum caps and paper labels is significantly greater than that required to convert polypropylene and polyethylene terephthalate into printed flexible film and subsequently into stand-up pouches. And, the energy needed to ship a truckload of glass containers from wherever they were produced - we think they come from Mexico) to the facility where they're cleaned, filled, capped and labeled is very likely greater than that needed to convert the requisite raw materials into film, ship the rolls to wherever they're made (and probably filled and sealed) into pouches. The lighter shipments of pouches from point of filling to distribution centers and grocery outlets no doubt consumes less energy than that required to transport an equivalent volume of tomato sauce in glass jars. Traditionalists will see the switch from glass jars to flexible pouches as a decision made for marketing and economic reasons. What's sustainability got to do with it?, they might ask. But the truth of the matter is that anything you do to extend your ability to continue is a sustainability initiative. And Unilever's migration into flexible pouches for sauce is an effective sustainability packaging strategy. Whatever the motivation, the move to lighter packages will definitely be seen as a positive sustainability play.

Since the first Earth Day (April 22) in 1970, it's often passed almost without notice. Not this year. The flurry of announcements from consumer packaged goods companies, packaging converters, trade associations and others show what a strong increase there has been in concern about the environment. In fact, figures from the Grocery Manufacturers Association indicate 75% of consumer goods companies say that sustainable packaging is more important this year than last, 62% expect to change their packaging within the next year with sustainability being a key consideration.

Another telling indicator of the importance sustainable packaging has gained is the shift by DuPont to instruct judges of the 20th DuPont Awards for Packaging Innovation to select winners based solely on sustainability criteria. It appears to be time to go green.

Cosmetic eye masks aren't the first product that comes to mind when someone says "recloseable stand-up pouches" but that's a category breakthrough for aluminum foil, and probably the underlying reason for Quies Sarl's "Beauty Purse(R)" eye masks pouch being honored by the European Alumininium Foil Assocition with the 2008 EAFA Trophy. The pouches, and other winners in the annual competition will be on display at this week's Interpack show in Duesseldorf, Germany. If you're there, stop by the PMMI stand in Hall 12, F01. See you there!
