The cold filling processes is a popular choice for the food, beverage and pharmaceuticals industries because it is not subject to the limitations and restrictions that come with the hot filling process.

What is cold filling used for?

Cold filling is most popular for fresh products like juice and milk because it reduces or obviates the need for preservatives and additives and still protects the products from bacterial contamination. Among the products that are usually cold filled are fruit and vegetables juices, tea and coffee beverages, sports drinks, milk-based drinks, UHT milk, water mixed beverages and flavoured waters.

The benefits of cold filling?

One of the major benefits of the cold filling process is that it assists in ensuring the safety of the product inside but there are many other benefits to note.

  • Lower costs
  • Different plastics can easily be used
  • Space and energy saving
  • Product quality is not affected
  • Nutrients are preserved
  • No change in taste (in the case of food items)
  • No added preservatives means that products are in a more natural condition

It is important to note that the cold fill process needs to be used in a largely sterile environment. Without the right environment, there is risk of product contamination so, air purification and air filtration are important components of the cold fill process.
