The modern pasteurization process requires heat, which in turn poses a challenge to today’s producers of dairy products.

Most people don’t think about how we get the milk that we drink every day and pour on top of our cereals. We simply buy it. But for one modern dairy producer, the dilemma presented by the pasteurization process proved to be an enormous threat to his company’s profit and efficiency.

The heating and cooling process of the dairy requires significant time. Dairy producers know that pasteurization is a vital process. It ensures that the dairy is safe and fit for consumption. Producers are also aware that the time it takes to heat and cool cream is extremely costly. The loss of time lends to decreased production volumes and causes dairy companies to lose profit. One specific dairy producer located in the UK was determined to find a solution to the predicament caused by the pasteurization process. Desperate to find a solution to his loss of profits, the dairy producer contacted IPS Packaging. IPS suggested the use of stretch film.

The dairy producer soon learned the benefits of using stretch film. Because of the stretch film, the product now only needed to be chilled for one hour. Individual cartons were stacked into pallet loads while the cream was still between 20°c-30°c. They were then wrapped using a regular stretch film and placed into a blast chiller. Two hours later, once the cream had fallen to less than 5°c, the load was moved, the stretch film removed, and the individual cartons shrink wrapped into multiple product units. Unfortunately, due to this process, the product then needed to be placed back into the chiller in order to cool it down again. Only when the products’ temperature was back below 5°c was it ready to once again be wrapped in stretch film so that it could finally be dispatched.

As a result of the utilization of stretch film, the dairy producer’s production line became less congested, improving production volumes by 100%. Since the product was permanently aerated, the load could also be cooled when it was in transit which also caused great production savings!
