Let's Package Milk

Now the milk is ready to be packaged for delivery to the stores where they will be sold. The milk travels through pipes to the automatic packaging machines that will fill and seal the milk into paper cartons or plastic jugs. As the containers move through the assembly line, a date is printed on each of them to show how long the milk will stay fresh. Compared to other foods such as cereals which can stay good for months, milk is sold to a more local market due to its limited freshness and costs of shipping to other areas. After packaging, the milk is finally ready for the customers, and it is stored in a big, refrigerated room until it is delivered to the stores to be sold.
