The proper resin selection for heat sealant layers is critical to ensure closure hermeticity and commercially acceptable heat sealing production rates. A mathematical model for heat sealing can be employed to design quality heat seals for flexible packaging films. This mathematical model and computer simulation describing the constant heat sealing process for linear, semi-crystalline polymer films has been applied to heat sealing process optimization related to the issue of sealant resin selection. The results of process design computations using this model for sealant selection and specification will be explored.
