Easy way to test quality of tube products
Stable Micro Systems has launched a new quality control device that quantifies the force required to extrude the contents from either tube or sachet style packaging.
Stable Micro Systems has launched a new quality control device that quantifies the force required to extrude the contents from either tube or sachet style packaging.
The Sachet/Tube Extrusion Rig is designed for use with the company's TA.XTplus texture analyser and allows manufacturers to gauge the ease of removal and application of products such as ointments, creams and gels.
Products packaged in tubes and sachets need to remain viscous or squeezable throughout their shelf life to enable the customer to obtain the product easily. But some products can become less viscous and get harder to remove over time.
This device allows manufacturers to test the force required to extrude the contents of a sachet or tube at regular intervals over a long period of time, throughout its shelf life and adapt formulations accordingly.
The new attachment also enables pharmaceutical manufacturers to assess the suitability of a packaging material and its construction.
The 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.
