Pharmaceutical Films — Texture Application Note

The strength of a film material can be quantified using the CT3 Texture Analyser by a penetration test using a 3 mm cylinder probe to determine the strength (rupture point) of the film material. A force is applied to the sample to deform the sample to rupture point. This is a common method also used to measure points of weakness in a film or seal during manufacturing, simulating circumstances whereby the material may burst during packaging and transport.

The CT3 Texture Analyser can also quantify the elasticity of the film by measuring the deformation at hardness.
