If you're looking to automate your liquid pouch packaging, there are three main things your packaging equipment manufacturer or integrator needs to know to provide the best liquid packing machine for your application.
Planning a liquid packaging machine project?
Viscosity is defined as a measure of a fluid's resistance to flow. It describes the internal friction of a moving fluid. In more informal terms, it's a measure of the liquid product's 'thickness'.
A liquid with higher viscosity, such as icing or molasses resists motion because its molecular makeup gives it a lot of internal friction. It doesn't flow as easily. In contrast, a fluid with lower viscosity, such as water or corn oil flows easily because its molecular makeup results in very little friction when it is in motion.
The mathematics required to calculate viscosity is much too involved for a packaging blog and can be most easily measured with special equipment. However, a simplified formula for measuring viscosity is as follows:
viscosity = shear stress / shear rate
or
μ = τ / γ
The answer is usually expressed in centipoise (cps). Water is the standard at 1 cps. A liquid product like honey would have a viscosity of about 10,000 cps. Condiments like ketchup or mustard have a viscosity of 50,000 - 70,000 cps.
So what does viscosity have to do with packaging, anyway?
CSC Scientific Company Inc., a provider of measuring equipment, explains that in the Consumer Packaged Goods (CPG) world, viscosity affects the rate at which a liquid product travels through a pipe, how long it takes to set or dry, and the time it takes to dispense the fluid into its packaging.
When it comes to selecting liquid packing machines, the viscosity of the product is a vital detail and must be accurate. Viscosity determines the type of product filler used: It must provide the right amount of force to induce flow, but not so much that the packaging will overfill.
When heated, most liquid products flow more readily. Picture the consistency of frosting or motor oil as it is heated; its viscosity lowers significantly and it becomes much more free-flowing.
Here's what's happening: When a liquid is heated, its molecules begin to move faster and faster. This movement is enough to overpower the forces that bind the molecules together, resulting in a more free-flowing liquid. Heat also causes a decrease in surface tension, further reducing viscosity.
How does this affect the packaging process?
The temperature at which the liquid product will be filled into the package is very important to the configuration of the packaging line, specifically when it comes to the product filler.
To provide the most efficient liquid packaging solution, providing an accurate fill temperature is a must. Inaccuracies in this area can result in packaging equipment that isn't specified for your needs, causing malfunctions and frustration.
Liquids like salad dressings, soups, and sauces often contain particulates. These particulates are usually spices and flavor additions like small vegetable pieces. Particulates can be suspended in the liquid product or they can settle toward the bottom of the fluid.
When packaging liquids with particulates, special care must be taken to accurately describe and measure their average size and general properties.
The presence of particulates will determine the type of product filler your liquid packaging solution will require for the most accurate and unimpeded dispensing.

With your requirements clarified, let’s have a look at the comprehensive range of liquid packing equipment:
Filling machines automate the process of filling liquid materials in containers. These liquid packaging equipment work by dispensing a specific amount of liquid into each container, ensuring consistency and efficiency in production lines. Filling machines are critical in industries such as food and beverage, pharmaceuticals, medicines, and cosmetics because they help to streamline production processes.
In addition to its precision and versatility, filling machines provide substantial benefits in terms of efficiency and productivity. By automating the filling process, they reduce the need for manual labor, limit product waste, and boost throughput rates, resulting in cost savings and increased competitiveness for manufacturers.
Overall, filling machines are a critical component of modern production, allowing for the efficient and dependable packaging of a wide range of products across multiple industries. Their contribution to optimizing manufacturing processes and maintaining product quality emphasizes their importance in today’s industrial scene.
Capping machines are vital in the packing business, as they securely seal containers with caps or lids. Capping machines increase productivity by automating the sealing process, which reduces manual work and ensures consistent, tamper-evident seals.
Capping machines serve an important role in industries such as food & beverage, pharmaceuticals, and cosmetics, where product safety and integrity are crucial. They help producers meet regulatory standards and industry best practices by offering tamper-evident seals and reducing contamination.
Capping machines are invaluable assets in modern packaging operations, providing adaptability, efficiency, and dependability. Their importance in the packaging business stems from their ability to ensure product quality, improve operational efficiency, and meet regulatory standards.
Labeling machines are critical pieces of equipment in packing processes, as they efficiently apply labels to diverse liquid packaging equipments, items and containers. Labeling machines improve industrial processes by automating labeling, saving manual work and increasing efficiency. They ensure accurate and consistent label positioning, which improves product presentation and brand image.
Labeling machines are critical in industries such as food and beverage, medicines, and cosmetics for ensuring compliance with regulatory standards such as ingredient lists, nutritional information, and warning labels.
