Peel Back Heat-Sealed Food Lids Without Strain
BOGNOR REGIS, UNITED KINGDOM – Lloyd Instruments, a market leader in the field of
materials testing instruments, has developed a fixture specifically to test the peel strength of
heat sealed plastic film covers on food containers. The peel fixture fits the company’s food
texture analyzer and single column testing machines and is designed to help both food and
packaging industries develop quality seals on food containers to the benefit of end users.
This precision engineered fixture consists of a small upper 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 securely into position. This advance capability not only ensures
accurate results and data reproducibility, but also safety during testing.
The peel fixture was designed specifically for a major international food company. It has 500 N
(112 lbs) force capacity and fits easily onto AMETEK’s TA1 texture analyzer or LS series of
low-force universal testing machines. The peel testing system currently handles containers
measuring 120 mm (4.724 in) in diameter. Additional holders, however, may be designed to
accommodate containers of other shapes and dimensions.
