The EarthSafe™ dispensing system was unveiled May 6 by Crown Holdings,
) to provide consumer packaged goods companies
with an alternative to traditional aerosol technology that uses
hydrocarbons as a propellant. The new package, Crown says, is a direct
response to a mandate by the California Air Resources Board
) to reduce the volatile organic compounds in certain
consumer products. The directive, which now has been adopted by nine
other sates, is on track to become law by Jan. 1, 2010.
According to Crown, the personal care products market, and shaving gel
products, in particular, will be drastically affected by CARB’s
mandate. The EarthSafe system targets these gel products, replacing the
hydrocarbon typically used in aerosol cans with compressed air that not
only reduces the product’s overall VOCs, but also allows for complete
evacuation of the gel product at a consistent flow rate.
The system has been under development for the past 12 to 18 months, in
cooperation with Ultramotive Corp. (www.ultramotive.com
), the patent
holder for the technology, relates Bradley J. Dahlgren, vp of sales and
marketing for Crown Aerosol Packaging USA. The system depends upon
three main innovations, he relates. The first is a patented, universal,
tamper-proof grommet that creates an airtight seal to enable the use of
lower pressure to discharge the product. The second is a newly
designed, multilayer barrier piston using Eval’s (www.eval.be
vinyl alcohol. This eliminates primary and secondary gas permeation,
extending the product shelf life. Third is an advanced valve technology
that allows total evacuation of the product at consistent flow rates
from start to finish.
The package is available in a 52-mm-dia size, in several heights, and
is fully recyclable. The package can also be decorated with unique
finishes to enhance the product’s on-shelf impact.
EarthSafe technology, unveiled at the Consumer Specialty Products
) 2008 Mid-Year Meeting in Chicago, is expected to
be commercial in 2009.
