Texture Analysis in Action: the Film Support Rig

Film Support Rig test using the TA.XTplus Texture AnalyserThe Film Support Rig (HDP/FSR) provides a biaxial extension approach to the measurement of burst strength of thin, film-like samples such as the increasingly popular breath strips, nori, leaf gelatine, wafer thin meats or rice paper. 

The sample is supported between plates which expose a circular section of the sample allowing a spherical probe to be pushed through to perform extension and elasticity measurements. During a test, the maximum force to rupture the sample (burst strength) is recorded.

Texture Analysis in Action: the Blister Pack Rig

Bister Pack test using the TA.XTplus Texture Analyser The BLISTER PACK RIG* (A/BP)
There are a range of tests available which quantify the characteristics of blister packs. Perhaps the most important test is to measure the force required to remove the tablet from its blister pack. 

This simple imitative test, which can be quickly performed on a complete strip of tablets, enables the average extraction force as well as the maximum and minimum extraction forces to be determined. 

Adhesive Product Physical Characterisation

Applying silver tapeAdhesiveness (often referred to by consumers as ‘stickiness’) is key to perceived product quality, performance and effectiveness.

It can be influenced by many factors, including temperature, liner material, moisture level and repeated use. By matching adhesive performance to functional and consumer requirements, manufacturers can identify the ideal adhesive composition.
