Packaging Thick Products Like Sauces, Oils, and Lotions Efficiently

Packaging high viscosity products like sauces, oils, creams, and lotions present unique challenges to businesses that are not typically seen with free-flowing products. Managing thick products to ensure clean, consistent fills means relying on precision-engineered machinery built specifically to handle high viscosities while maintaining product quality and process efficiency. At Liquid Packaging Solutions, we design and build filling systems for these products that simplify even the most demanding applications and help businesses package with confidence.

The Challenges of Packaging Thick Liquids

Lower viscosity, thin liquids flow freely through product pathways, whereas thicker products often require an additional push and extra control during the filling process. These liquids, due to their viscosity, tend to move more slowly and cling or stick to surfaces, which can cause inconsistent fills if not handled properly. Not designing equipment specifically for their viscosity can lead to dripping or stringing during the fill process, inconsistent fills from product buildup in the pathway, and even increased or unnecessary wear on certain components. To minimize or overcome these issues, the right type of liquid filling machine must be matched to each specific projects unique characteristics.

Choosing the Right Filling Equipment

As noted above, for thick products, a little extra push is often necessary for an efficient filling process. For this reason, pump and piston filling machines are the most-used types of equipment for high-viscosity liquids. Pump fillers will match the pumps used to the specific application to ensure precision and consistency in moving thick products. Pump types may include gear pumps, lobe pumps, or even peristaltic pumps or others where a variety of flavors or colors are run. Piston fillers are also ideal for thick products, especially those that typically have particulates, like salsa, fruit jams, salad dressings, and similar items.

Both pump and piston filling machines offer that extra push that will help viscous products move through the product pathway with efficiency. By analyzing each project, including the liquid, the containers, unique characteristics, the space, and more, LPS ensures each custom machine built for thick liquids is also built to meet the specific needs of each business.

Integrating the Complete Packaging Line

Of course, an efficient filling machine is only one part of an efficient packaging system for thick products. For many businesses, the pump or piston filling machine will work with bottle rinsing machines, capping equipment, labeling equipment and other packaging machinery. Whether integrating with other LPS machinery or OEM equipment, LPS filling machines are built to roll right up to a conveyor and work in conjunction with other machinery.
