Stable Micro Systems has announced the launch of its new Sachet/Tube Extrusion Rig - a device which quantifies the force required to extrude the contents of tube and sachet style packaging
Designed for use with the TA.XTplus texture analyser, the innovative attachment allows manufacturers to gauge the ease of removal and application of products such as ointments, creams and gels.
A large proportion of pharmaceutical, cosmetic and personal care products are often produced in sachet or tube portions for quick and convenient use, as well as to facilitate long-term storage.
Removal of the contents relies on the consumer's ability to squeeze the packaging, and on the consistency of the product, assuming the aperture of the tube/sachet remains constant.
By testing the force required to extrude the contents of a sachet or tube at regular intervals over a long period of time, product developers can analyse changes in a product's consistency throughout its shelf-life and adapt formulations accordingly.
The new attachment also enables manufacturers to assess the suitability of packaging material and its construction.
Stable Micro Systems's new rig positions the product vertically between two rollers, clamping the closed end with a grip at the top.
The grip then pulls the sachet/tube upwards through the rollers, forcing the contents out.
The higher the force recorded during this test, the more difficulty a consumer would experience in squeezing out the required amount.
As the contents' consistency is fundamental to effective extrusion, the new instrument can help manufacturers create optimum product formulations.
The Sachet/Tube Extrusion Rig is the newest addition to Stable Micro Systems's comprehensive range of testing instrumentation.
It can be used to produce accurate analysis of a wide range of pharmaceutical, cosmetic and personal care products including ointments, lotions, gels and creams as well as toothpaste, shampoo and make-up.
