Peel Strength Testing For A Flexible Friend

Lloyd Instruments has introduced a new test jig for peel strength testing of laminated layers of standard plastic identification cards to international standards. The use of plastic cards is reaching unprecedented levels, with at least one credit or debit card, driving licence, or loyalty or membership card being found in almost everyone’s wallet or purse.

The new TG113 90° peel test jig includes an upper wedge grip and lower fixture containing rollers, which can be used in conjunction with one of Lloyd Instruments’ low force universal materials test instruments such as the LFPlus tester. The jig allows 90˚ peel tests to be made at forces up to 200 N (44.96 lbf) for the measurement of peel strength between card layers in accordance with ISO/IEC 10373-1:2006 (E).

The strip to be tested on the card is attached to an adhesive tape loop. This is passed through the roller assembly and held securely by the upper clamp so that the face of the card rests on the underside of the rollers. The grip therefore clamps the prepared card test layer so that a peeling angle of 90° is maintained during measurement. Up to four test strips per card may be prepared and tested.
