Imagine this: you’ve ordered your favorite pasta dressing. It arrives, only dripping from the sides. Yes, we know what you’re thinking. Gross, right? That’s what happens when a liquid food product with particulates comes with a poorly done seal. And, that’s one instance. The point is: robust packaging is at the core of packaging liquids.
But, it’s easy to lose the way, given the amount of expertise that’s floating on the web. We are here to narrow it down for you, tell you what’s best, and about the only things that you need to know for now.
Liquids can get messy and stale quickly, and therefore, it is imperative that we accurately define the viscosity of the product. Once that is done, it will be easy to zero in on the kind of packaging and filling solutions one needs to aim at.
However, that’s not everything you need to focus on. One must pick machines based on the product’s foaming nature, temperature, and particle size as well.
Also, having access to appropriate filling machines also = keeping contamination and wastage at bay.
Gravity and pressure filling machines
Water-thin liquid food products such as milk, soda, juices are filled into tetra packs, boxes, pouches, using these fillers. These machines can either run by operators, who judge the volume of product that is to flow into each container, or one can go for the ones that control the volume without the operator present, which makes it more precise and fast.
They help fill up containers/ packets with liquids of low to high viscosity. Sauces, pickles, and jams – liquid products that don’t flow that smoothly – are filled using a machine that is run by a moving piston that pushes contents from the cylinder to the container.
Low-viscosity liquids are best suited for these kinds of fillers. They are designed to provide consistent fill levels.
It’s not as complicated as it sounds. These different types of machinery will not only help (those interested) in reducing waste but also increase accuracy.
But this alone is not enough to get your liquid food business going. If you’d like more customers haranguing you for that lip-smacking lip that just sold out from the display shelf at the supermarket then this is what you must keep in mind too.
If your food is not sealed properly, it’s going to go to waste. Liquid food products turn bad in a matter of days if not secured correctly. And for that to happen one will need access to machinery that helps to ease this. However, you must also keep in mind that the cappers you rent/ buy should be compatible with your packaging (pouch/ bottles/ tetra packs) material or, else it will not deliver consistent results.
Snap cappers, Automatic vertical wheel pluggers, spindle cappers, and chuck cappers are some of the crucial equipment to look at.
Product filling is surely a challenge but it’s followed by another massive task – packaging. The choice of containers, the characteristics of the product, and such will all come into play. If not thought about ahead of time, these factors could pose serious problems in the manufacturing process, resulting in huge losses.
Nature of products
Food products are highly corrosive but they can be reactive. Therefore, clear glass bottles are best suited for such products. Once the nature/ characteristics of the product are determined, it’s easier to assess and finalize packaging solutions.
Types of seals
Bottle and jar closures can be grouped into three categories: Pressure seals, which are mostly used for carbonated beverages such as cold drinks and such. Crown caps, steel caps, twist-off steel caps, and vacuum seals are some of the other options.
Two cents: Please remember to thoroughly assess your liquid products before you invest in any filling or capping machines.
Lastly, consider the look and feel of your final products that have been filled, sealed, and packaged. The functionality of your containers matters but so does the look. Therefore, be very wary of the kind labeling, font type, and size you are going for because that would make a huge difference to the year-end numbers.
