Measure Firmness


Measurement of firmness and related properties using the TA.XTplus Texture AnalyserFIRMNESS/HARDNESS/SOFTNESS are textural properties that are on the same general property spectrum. 

A soft product is one that displays a slight resistance to deformation, a firm product is moderately resistant to deformation, while hardness describes a product which shows substantial resistance to deformation. 

However, it is also likely that, depending upon the particular industry, one of these words may be more favourable or pertinent to a specific product.

Sticky standards for your adhesive tape testing


Application of heavy duty silver tapeAdhesiveness / Tackiness / Stickiness are key to perceived product quality, performance and effectiveness of such products as sealing tapes, adhesive plasters and labels used in the pharmaceutical, food, medical and packaging sectors.

These properties 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.

However, a measurement principle needs to be adopted so that these properties can be monitored either during the development stage or at the point of quality control.
