Important Factors in Filling Process of Liquid Packaging Industry
Whether you need to package gels, thick creams, or semi-liquids, flexible packaging offers several benefits. Modern, flexible packaging machines have made the process of liquid packaging easy, quick, and clean. The following are three factors about product filling and automated liquid pouch packaging.
Keep viscosity in mind
Viscosity refers to the resistance of a fluid to flow. It describes a moving fluid’s internal friction.
Therefore, a more viscous liquid moves slow, as it’s resistant to flow. A less viscous fluid has less internal friction and will flow more smoothly.
Viscosity is an essential factor to consider when it comes to liquid packaging since it affects the speed with which the liquid travels through the pip, sets, and dries, and is dispensed into the packaging. Be sure to measure viscosity accurately for proper packaging. Viscosity will also determine the kind of product filler you need. It will have to supply enough force to encourage flow, but not so much that there will be overfill.
Consider the fill temperature
The temperature your fluid product is filled at is critical to the packaging process, especially where the product filler is concerned. Liquid products will flow more easily when heated, as it causes viscosity to decline and they become freer flowing. Make sure to provide the right fill temperature to assure the correct packaging of your product.
Particulate size matters
Certain liquid products have particulates. These particulates could settle at the bottom, or they may remain suspended within the fluid. It’s important to measure and describe accurately the average size of these particulates, as well as their general properties, which will affect what kind of product filler you will need.
