Have you ever stopped to think about the packaging of milk? Most of us take it for granted, grabbing a carton or bag from the fridge without a second thought. But have you ever wondered why some milk comes packaged in a bag inside a carton, or why some cartons have a peculiar square shape? In this post, we'll explore the fascinating world of aseptic packaging, specifically focusing on the phenomenon of milk inside a bag of milk.
One of the pioneers in aseptic packaging was the Swedish company Tetra Pak, which introduced its iconic Tetra Brik carton in 1951. The Tetra Brik design featured a square shape with a flat, rectangular base, which allowed for efficient packaging and transportation. But what makes Tetra Brik cartons truly unique is the presence of a plastic bag inside the carton, which contains the milk. milk inside a bag of milk free download
So, why is milk packaged in a bag inside a carton? The reason lies in the process of aseptic packaging. When milk is packaged aseptically, it's first sterilized using ultra-high temperature (UHT) processing, which involves heating the milk to a high temperature (usually around 135°C) for a short period, followed by rapid cooling. This process kills off any bacteria and extends the shelf life of the milk. Have you ever stopped to think about the packaging of milk
