A fixture designed to test the peel strength of heat sealed plastics film covers on food containers has been developed by materials testing specialist Lloyd Instruments.

The TG 5093 is designed to help both food and packaging industries develop quality seals on food containers.

It comprises a small spring loaded wedge grip to hold the film cover and a horizontal sliding bed with a ‘dish holder’. A vacuum system is used to grip the food container in position.

Originally developed for an international food manufacturer, the system handles containers measuring 120mm diameter, however additional holders can be designed to accommodate other shapes. TG 5093 has a 112lb forces capacity and fits onto Lloyd’s LF, LR or Plus low force testing machines.
