Business Wire
Constar International Inc. (NASDAQ:CNST) today introduced Vertical
Compensation Technology� (VCT�), an innovative, panel-less hot-fill
technology for PET containers. Constar developed VCT technology to
provide its PET bottles and jars with the look and premium feel of
glass and robust in-hand feel, targeting glass-to-plastic and
plastic-to-plastic conversions for hot-fill beverage and food
products. Constar�s VCT technology employs distinctive geometry to
address the natural stresses placed on PET bottles and jars during
the hot-fill process. Designed using Constar�s CONSTruct� advanced
predictive engineering software, the distinctive hoop geometry
eliminates the need for vacuum panels by allowing the bottle or jar
to flex vertically to compensate for the vacuum created in the
hot-fill process. One of its major benefits is improved
productivity during the filling process as the smooth sidewalls and
rigidity facilitate the high-speed application of roll-fed labels.
This also replicates the in-hand feel of traditional glass hot-fill
bottles and jars�no �crinkly� label feel�giving it a sensory
advantage over current six-panel hot-fill PET containers. The end
result is a very strong PET container that has the look and premium
feel of glass. Customers converting from glass to Constar�s PET
containers with VCT technology secure considerable sustainability
benefits. These PET containers are far lighter in weight than
glass, resulting in freight and energy savings. With fuel prices
continuing to rise, this benefit continues to grow. From a consumer
perspective, used PET containers are accepted by curbside recycling
programs. Used PET has a high market demand and recovery value,
finding its way back into bottles and into products like carpet,
clothing and sleeping bags. Commenting on the announcement, Constar
Senior Vice President-Sales and Marketing Dan Ingram said the
market is ripe for hot-fill PET bottles and jars that deliver the
visual aesthetics and tactile experience of glass. �PET offers
significant cost and sustainability advantages for hot-fill foods
and beverages, yet the traditional six-panel design is not entirely
satisfactory for many glass container conversions. The unique
geometry of VCT containers breaks down those barriers; it has the
same robustness and rigidity of glass. And that�s key to companies
looking to convert from glass to PET,� he explained. Constar�s VCT
hot-fill panel-less technology is available in stock and custom
designed bottles and jars. About Constar International Inc.
