Top Three Factors that Play the Game in Liquid Packaging

Whether they are thick creams, sauces, gels, or even water, the packaging of these liquid products is quiet tricky to deal with. Manufacturers that are involved in producing liquid type products should opt for best and ideal packaging method that uses modern flexible packaging machines. This makes the entire packaging process clean, quick, and stress-free. In the present times, the liquid packaging market is gaining enormous fame due to significant rise in the demand for liquid packaging from the food & beverage and pharmaceutical industries.

If you are someone who is looking to simplify and automate your liquid packaging process, you have come to the right place. Here are 3 main factors you or your packaging machine manufacturer should understand to choose or offer the best liquid packing equipment for your liquid products.

1. Viscosity of the Liquid Product

Viscosity is nothing but a measure of the resistance of a liquid to flow. It defines the internal friction of a liquid in motion. In simpler terms, it denotes the liquid product's 'thickness'.

When a liquid has greater viscosity, such as syrups or icing, it restricts itself from flowing easily as its molecular formula gives it lots of internal friction. On the other hand, when a liquid has lower viscosity, such as corn oil or water, it does not restricts itself from flowing as its molecular formula gives it a much less friction and allows it to flow easily.

So what does the viscosity of the liquid have to do with packing, anyhow?

Experts say that in the world of the Consumer Packaged Goods (CPG), viscosity impacts the degree at which a liquid flows through a pipe, the time it needs to set or dry, and the period it needs to pour the liquid inside the packaging pouch or container.

While choosing a liquid packing equipment, the liquid product’s viscosity is an important thing to be measured and should be precise. Viscosity helps in deciding the type of product filler that should be used in packaging equipment to enable proper packaging of the liquid product.

2. Temperature of the Liquid Product while Packaging

While heated, most of the liquid items flow more easily than their original capacity. When liquid products are heated, their viscosity gets affected. For instance, the steadiness of motor oil gets affected when it is heated; this is because its viscosity is reduced considerably, which helps the liquid to flow more readily.

When liquids are heated, their surface tension also decreases, thus decreasing their viscosity.

So, what does the temperature of the liquid product have to do with its packaging?

Considering the accurate temperature of the liquid product at the time of packaging is extremely vital for setting the configuration of the packaging equipment, mainly in the case of product fillers.

Inaccurate temperate consideration of the liquid product can lead to breakdowns and frustrations in the overall packaging process.

3. Size of Particulates in Liquid Products

Liquid products such as soups, salad dressings, and pastes usually have particulates. These particulates are generally pieces of spices and flavor add-ons such as tiny pieces of vegetables. In liquid products, particulates usually get suspended or settle towards the bottom of the liquid.

While packing liquid products with particulates, extra care should be taken to correctly define and measure the average size as well as basic properties of the particulates.

The size of particulates will help in determining the type of product filler that should be used in the liquid packaging equipment for easy and unhindered product distribution in the packages.

Key Takeaway Message for Liquid Product Manufacturers!

Ensure that your next liquid packaging equipment is built in a way that satisfies your products’ needs taking into consideration factors such as product’s viscosity, temperature while packaging, and size and properties of particulate. Keep an eye on these key factors and your liquid product packaging will be a success and stress-free.
