Case Study: Enhanced Seal Quality & Manufacturing Efficiency
Packaging Reliability Up 23%:
Adept Transforms Lid-Sealing Operations
A large yogurt manufacturer came to Adept because their paper-based lids were frequently tearing upon opening, with about 25% of lids removing in two or more pieces.
Adept helped resolve the issue by improving single-piece lid opening rates from 75% to 98% across all factories. Through root cause analysis, process optimization, and staff training, Adept enhanced seal quality and machine performance, resulting in a better consumer experience and increased operational efficiency.
By implementing vacuum testing and standardized troubleshooting guides, Adept provided a long-term solution that ensures consistent packaging integrity and improved manufacturing reliability.
Core Challenge Identified: Material Selection and Machine Setup Misalignment
- The material of the lid and the sealing process on the machine.
- The client did not have a good understanding of the principle of the sealing material design.
- There were knowledge gaps in the of the machine and how it created the proper conditions for sealing
Results
- Improved sealing across all factories.
- Tearing performance was improved from 75% single piece opening to 98%.
- Consumer preferred opening of container
- Increased OE as a result of sealing process optimization in the factory.

Steps Taken by Adept
- Root cause analysis was conducted and an in-depth understanding of the lidding material and the sealing process in the factory was developed.
- Factory and R&D staff were trained in the sealing and material technology.
- Troubleshooting and Development guides were developed and presented to the factories as well R&D and Engineering.
- Vacuum testing of seals was implemented on all production lines and is now used to measure seal quality and manage performance in the Factory
- Sealing Optimization was conducted across all factories and machines.
