With growing demand for packaging that supports a greener, more
energy efficient world, Constar International (NASDAQ:CNST) scored
a major victory when its DiamondClear� PET bottle for ConAgra
Foods� Hunt�s Ketchup was recognized by the Institute of Packaging
Professionals (IoPP) as the top sustainable package of 2007. Today,
the IoPP announced Constar as the recipient of the prestigious 3M
Sustainable Packaging Award, one of the overall awards of the
AmeriStar competition in 2007, and the only one recognizing
sustainability. Constar also won the 2007 AmeriStar Food Category
Award for the same package. ConAgra Foods converted its 46-ounce
Hunt�s Ketchup product to Constar�s DiamondClear� PET bottle in
2007, a revolutionary package that offers exceptional clarity and
barrier performance in a lightweight PET bottle, and other sizes
followed shortly thereafter. Commenting on the award, Constar CEO
and President Mike Hoffman said, �It is tremendously gratifying to
be recognized by our industry in this way. The AmeriStar 3M
Sustainable Packaging Award is a tribute to ConAgra, who saw the
value of our technology, and to our people, who pushed the
boundaries of materials science and engineering to bring
DiamondClear� to life. It is a privilege to be able to offer a
package that meets the goals of sustainability, product protection,
and merchandising.� The winner of the 3M Sustainable Packaging
Award is selected from all entries to the annual competition.
Scoring is based on efficient energy usage, recycling efforts,
effective use of packaging materials, and/or eco-friendly raw
materials. Constar�s DiamondClear PET bottle for Hunt�s Ketchup was
selected from more than 100 entries, earning high marks for being
lightweight and compatible with current recycling practices. PET is
among the easiest of all plastics to recycle and reuse. The
DiamondClear� material is an active oxygen scavenger that is
blended directly into PET in a monolayer structure. The technology,
in this application, was a replacement for multi-layer PET with
EVOH, a passive barrier material. The monolayer structure of
Constar�s DiamondClear� PET has a number of advantages over
multi-layer PET including better integrity (no delamination), as
well as lower manufacturing complexity and cost. DiamondClear� PET
facilitates light weighting of a package through a combination of
factors. Its high capacity for scavenging oxygen allows for thinner
walls without appreciable loss of barrier. At the same time, the
reduction in wall thickness can be realized without risk of
delamination, an important factor for any bottle, but especially a
squeezable ketchup bottle. For Hunt�s 46-ounce ketchup bottles,
these factors provided a weight reduction of nearly 12 percent, a
significant sustainability gain. DiamondClear� provides glass-like
clarity, a real breakthrough for an oxygen scavenging material that
is blended directly into PET. Its exceptional barrier performance
preserves the vibrant red color and flavor of Hunt�s Ketchup, while
delivering optimum presentation on the shelf. Once the product is
gone, consumers can place the empty bottle in a curbside-recycling
bin. About Constar International Inc. Philadelphia, Penn.-based
