Closures provide the boundary between your product on the inside of the package and the outside world. When it fails, you face the wrath and disappointment of the consumer when the "leaker" dispenses product all over the outside of the package and everything around it. Those who have experienced this problem understand the complexity and challenges of designing a good sealing closure system for high-volume or commodity-level packaging/sealing applications.
By building on sealing expertise originally gained in the early 1980?s for high-pressure/high-temperature applications in the petrochemical industry, Stress Engineering has fine-tuned methods for engineering sealing performance for plastic closures. These methods take into account critical design and process related-parameters such as:
Using this information as input to the analysis, we can optimize the performance of gasketed, plug, claw and nub-style closure systems. These techniques are also used to guide the development of new proprietary closure systems that may be needed for your application.
