Know your consumer: Spitz International shrink-wraps its sunflower seed package with a wax-lined paper cup that doubles as a spittoon for seed hulls. It fits in car cup holders.

An 8-oz. bag of sunflower seeds is packed in the spittoon — which is a wax-lined paper cup — and the package is shrink wrapped. The spittoon is proportioned for car cup holders.

Spitz is addressing convenience in other ways, as well. “Currently we are the only sunflower seed company that offers resealable packages on all our large single-serve and take-home items,” says Chris Tamillo, national sales manager at Spitz. In addition, “We have expanded our product line to include a 2.25-oz., convenient tube size that fits easily into a briefcase, purse or pocket for today’s on-the-go crowd.”

Green initiatives

Snack processors are taking sustainability to heart in both processing and packaging. Frito-Lay purchases renewable energy certificates (RECs) to offset the electricity it uses to produce SunChips snacks in the U.S., and the company uses its packaging to communicate the effort.

Specifically, Frito-Lay includes the Center for Resource Solutions’ Green-e symbol on SunChips packaging to show it supports green energy through the purchase of RECs. SunChips is one of the first national brands in any category to use the symbol on its packaging.

The Frito-Lay RECs are part of the PepsiCo RECs purchase, announced last year, that matches the electricity use of all Frito-Lay U.S.-based facilities, including the manufacturing sites that produce SunChips snacks. (Electricity is one of several energy sources used to produce SunChips.)

 

Note to Marketing 
The best way to sell some snacks is to let them sell themselves—by making them visible through the package.
Taking this tack with the Balance Organic Bar, which is bursting with chunky ingredients such as soy crisps, nuts and fruit, Kraft Foods Inc., Northfield, Ill., uses a transparent film to package the bars. The film, supplied by Alcan Packaging, Chicago, provides high optical clarity and robust barrier properties.
A window onto the product also plays a key role in a redesigned club-store package for Crunchmaster Rice Crackers from TH Foods Inc., Loves Park, Ill. In creating the redesign, Design North, Racine, Wis., recognized a window would be an important component of the package because rice crackers are a new category for club stores, and consumers want to know what the product looks like.
Although the packaging puts a strong emphasis on product photography, the window showing the crackers is necessary to fully convey the product’s attributes. “From a textural standpoint, the window delivers. It communicates texture and crispiness that you might not get in the photo,” explains Design North’s president, Lee Sucharda III. “Seeing is believing.”

Other green approaches include lightweighting packaging materials and structures. For the form-fill-seal bags in which it packages its all-natural potato chips, Kettle Foods Inc., Salem, Ore., recently switched from plastic-coated paper to all-polyethylene film bags.

Making packaging more environmentally friendly is difficult for snacks like chips, which require high-barrier, oil-resistant packaging. “You reach a limit where technology puts up the barricade, and this is as green as you can get,” says Jennifer Hauge, Kettle’s marketing communications manager. However, she adds, “We want to be on the forefront of whatever technology exists to have greener packaging.”

Switching to the polyethylene bag, which uses 20 percent less material than the paper-based package, is a step in that direction. “We’ve reduced [the package] on the whole, which is the most we can do in terms of making it greener,” Hauge says. She explains that currently there are no recyclable or biodegradable films that can sufficiently protect the freshness and flavor profile of Kettle chips.

Michael Osborne Design, San Francisco, designs the graphics for Kettle’s packaging, and Printpack Inc., Atlanta, supplies the bags.

Taking a different green approach, Clif Bar & Co. Berkeley, Calif., is sponsoring a program to keep energy bar wrappers out of landfills. Clif Bar has created the initiative, called the Wrapper Brigade, with TerraCycle Inc., Trenton, N.J., which provides wrapper collection and reuse expertise.

Wrapper Brigade participants receive four collection bags that hold 200 energy bar wrappers each. They mail the filled bags back to TerraCycle, designating the charity they want to support with their wrapper donation; the program will donate two cents to charity for every used wrapper. All shipping fees are covered by the program to encourage people to collect as many wrappers as possible.

The collected wrappers will be fused and woven into a material that will be used to make backpacks, gym totes and other products. These items are expected to be available at major retailers by early 2009. Free sign-up for the Wrapper Brigade is available at www.terracycle.net/brigades.

Clif Bar also uses non-toxic inks and recycled-paperboard in its packaging, has eliminated shrink wrap and has developed litter-reducing innovations like the stay-attached tear top on Clif Shot gel packets.
