The problem with existing coffee packaging is one-way-valve operation allows for failure.  Often particles will get caught in the passage ways and thus render the valve in the open position with no way to close. Another problem is inherent in the production process itself where product is either packaged stale or without adequate oxygen barriers. O2i has a comprehensive line of solutions that can allow the coffee roaster to consistently offer fresh product that is easily identifiable as superior to their competition's. Let us evaluate both your product and your process using our own proprietary lab equipment designed and built with the assistance of the University of Guelph Ontario.
