Proseal has launched a unique seal quality testing system that enables food manufacturers and processors to determine the ideal seal and peel strength for individual products. The ProTest solution allows users to create the best seal each time, combining effective protection of the contents with the right level of ‘peelability’ that ensures maximum consumer convenience.

The compact and easy-to-use ProTest unit is an automated lid-peeling device that measures and reports the resistance offered by the film as it separates from the tray during the moment of lid peeling.  This provides the user with the relevant data to determine if the seal strength is the most user-friendly while remaining suitable for the product’s life cycle.

ProTest is capable of retaining, displaying and outputting test data, allowing the user to export the information.  Up to five test results can be compared at any one time.  The unit is flexible enough to handle the vast majority of trays currently used in the market with diagonal diameters from 25mm up to 380mm in any shape.

Reports are generated on the machine’s 12” high-definition touchscreen and can be exported via Ethernet or USB device. This provides users with traceability records and the information to monitor peel strengths throughout production. 

The ProTest unit requires only 1200mm x 400mm of bench space and a 3 pin 230v power supply, offering a highly cost-effective means of providing in-house seal integrity analysis without the need for costly, off-site third-party testing.
