Development of optimized one-way vent valves for coffee packaging

In this project, the intern will tackle the production challenges currently faced by the industrial partner. Specifically to overcome inconsistent open/close pressures of a low profile vent valves intended for active packaging of roasted coffee. Vent valves, made of multiple layers of polymeric materials, are capable of relieving the internal pressure of a coffee package due to gradual degassing of CO2 from the roasted coffees, effectively preventing package failure and product staling. The intern will investigate the performance of production and prototype valves, study of the material properties of the polymeric membranes and sealing liquids, and develop methodologies to resolve the production issues. The findings will allow the optimization of open/close pressure of the vent valve, in order to meet CCL’s customers specifications and ensure successful production scale up, enabling the company to capture Canadian and world-wide market.
