Imperm®
Application:

 
 

 
 
 
 

Goals:




 

Details:

The customer produces multi-layer ketchup bottles and was experiencing a higher than acceptable level of rejects, due to difficulties in processing EVOH as the barrier layer. The customer is looking to replace the EVOH with a more cost effective material that allows for easier processing, maintains barrier properties, and is cost effective.
  • Replace EVOH with Imperm®
  • Reduce percentage of rejects due to delamination
  • Maintain current level of barrier
  • Maintain costs

The customer successfully completed the barrier layer replacement. In addition, Imperm eliminated the need for tie-layers, lowering the reject rate by 71%, while maintaining the barrier properties, and the same cost, even before calculating the cost savings of lower reject rates.

Advantages:

The customer met all of their original expectations including lowering reject rates, maintaining barrier properties, and keeping the project cost competitive. Further, the customer determined that there is no longer a need for tie-layers, and the actual barrier properties were further improved in high humidity testing. Finally, Imperm provided a cost savings due to a significant reduction in reject rates.

Customer Completion:

The customer was able to complete a trial with Imperm, and move to commercial status without any changes in processing conditions.
