Bottle supplier Constar International Inc. has introduced Vertical Compensation Technology, a panel-less hot-fill design for PET containers. Constar developed VCT to provide its PET bottles and jars with the look and premium feel of glass, targeting glass-to-plastic and plastic-to-plastic conversions for hot-fill beverage and food products.
Designed using Constar's CONSTruct advanced predictive engineering software, VCT's 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.
VCT is available in stock and custom-designed bottles and jars. Constar is based in Philadelphia.
