The Enviroclear Barrier Coating Technology was developed by the CSIR to extend product shelf life by significantly reducing the penetration of oxygen and the loss of carbon dioxide through plastic packages. When applied to a 500ml PET or polypropylene bottle, the Enviroclear technology provides an oxygen (O2) barrier of .001cc/pkg/day (42 x's uncoated PET) and .0025cc/pkg/day (25 x's uncoated PET) respectively. When applied to a PET 12oz carbonated soft drink bottle, the barrier improvement factor (BIF) is 6.4 times for carbon dioxide (CO2) retention compared with a standard PET bottle.
Enviroclear's recycling and sustainability benefits are a superior alternative to current materials based barrier technologies, which can pollute recycling streams. In addition, and because Enviroclear is applied to the outside surface of the package, the technology has a zero impact on product sensory performance.
The Enviroclear Barrier Coating Technology has been successfully applied to plastic closures, thermoformed tubs and other forms of packaging with the same superior results as when applied to plastics bottles.
Hot fill oxygen sensitive bottles for single serve juice and other glass and can replacements are a core objective of the Enviroclear Barrier System.
The cost of the finished barrier bottle has proven to be the most cost effective of any other alternative in the market today with better barrier results.
Combined with Container Corporation of Canada's Enviroclear Technology, which can produce a two stage injection stretch blow mold clarified polypropylene bottles and wide mouth jars, that are as clear as glass, results in a viable, economical alternative for hot fill barrier packaging.
As the chemistry is benign it does not change the resin identification number designation on the bottom of the bottle.
Norman Gottlieb, CEO of Container Corporation of Canada, says that this achievement demonstrates the company's commitment to providing the marketplace with a superior barrier technology, which is environmentally friendly and cost effective.
Container Corporation of Canada also supplies the bottle blowing equipment and application equipment for the Enviroclear Barrier System and is pleased to license the technology.
