This accessory is a device for testing the contents of extrusion packaging bags. This design of physical property tester (physical property analyzer, texture analyzer) can provide manufacturers of medical, cosmetics and personal skin care products with the ability to quantify the difficulty of such packaging extrusion products. Applications include ointment, cream and colloid. In this device, the product is clamped at the upper end of the assembly, perpendicular to two rollers. Assemble by pulling the sample upwards with a roller to test the force required for extrusion.

The physical property tester (physical property analyzer, texture analyzer) evaluates the applicability of packaging materials and structures by designing the appearance of the packaging and changing the concentration of the product.
