  For many products, the impact of packaging on shelf life and product safety is critical to success. Packaging technical teams will carefully specify packaging material characteristics in terms of functional and barrier properties, for example Oxygen Transmission Rate for an oxygen sensitive product. Despite this, the highest risk to pack integrity and shelf life can be failures in the pack heat seals or closures.

  Heat Seal parameters are easily measured; Heat Sealability = Temperature + Pressure + Time. Yet maintaining optimum heat sealing conditions in production and recognising the true cause of poor sealing remains a challenge. Learn More...
