Any product designed to be squeezed from a tube or other flexible container by the user must have one essential characteristic – squeezability.
This might appear obvious; but how can you determine the behaviour of your product and ensure that it meets customer needs?
Ready-made convenience sauces and condiments are often produced in sachet or tube portions for quick and easy 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.
It's not so problematic with the use of a Stable Micro Systems Texture Analyser and, for example, the Sachet/Tube Extrusion Rig, which enables you to quantify the forces needed to propel your product – whether it is a paint, a ketchup, or a conditioner – into the outside world.
