Key points of liquid pouch packing machine: 3 important details you must know

Whether it is sauce, thick cream, gel, even water, liquid package can be fast, clean and easy to use modern flexible liquid pouch packing machine for packaging. If you want to automate liquid bag packaging, packaging equipment manufacturers or integrators need to know three things to provide the best liquid pouch packing machine for your application.
Viscosity is another name of liquid packaging, viscosity is defined as the measurement of fluid flow resistance. It describes the internal friction of a moving fluid. Liquids with higher viscosity, such as frosts or molasses, prevent movement because their molecular composition causes a lot of friction inside them. Fluids with lower viscosity, such as water or corn oil, are easy to flow because their molecular composition moves with little friction.
For packaging users, the calculation of viscosity requires too much mathematics, and can be measured most easily with special equipment. However, the simplified formula for measuring viscosity is as follows:
Viscosity = shear stress / shear rate.
It is usually expressed in centipoise (CPS). Water is the standard of 1 CPS. Liquid products like honey have a viscosity of 2000-3000 CPS. Condiments such as ketchup or mustard have a viscosity of 50000-70000 CPS.
In the world of packaged consumer goods (CPG), viscosity affects the speed of liquid products through the pipe, the time of solidification or drying, and the time. The fluid needs to be distributed into its packaging. In the selection of liquid packaging machine, the viscosity of the product is a crucial detail, must be accurate. Viscosity determines the type of product filler used: it must provide the appropriate force to cause flow, but not so large that the package is overfilled.
1. The filling temperature affects the viscosity of the liquid
The filling temperature of liquid products is very important to the packaging project, especially in the product filling. After heating, most liquid products flow more easily. Describe the degree of frost or oil consistency when heated; Its viscosity is significantly reduced and it becomes more free flowing. In order to provide the most effective packaging solution for liquid packaging machine, it is necessary to provide accurate filling temperature.
Size is very important
Liquids such as salad dressings, soups and sauces usually contain particles. These particles are usually spices and flavorings, such as small pieces of vegetables. The particles may be suspended in the liquid product or may settle to the bottom of the liquid.
When packing liquids with particulates, special attention must be paid to the accurate description and measurement of their average size and general properties. The presence of particles will determine the type of product filler your liquid packaging solution needs to achieve the most accurate and unobstructed distribution.
