UHT = (Ultra High Temperature pasteurization and packing) P>
It is called UHT milk, which stands for Ultra Heat Treated. During preparation it is brought almost to boiling point, which kills more bugs than pasteurisation, so the milk 'keeps' for longer than pasteurised milk.
The shelf life of boxed milk is typically around 6-9 months. It can be stored for this period before it expires.
The reasons for processing milk is 1. to prolong the shelflife of the milk and 2. to eliminate the pathogens (bad bacteria) that may be present.
In 1856 by Gail Borden as an alternative to fresh milk which couldn't be kept for long without refrigeration.
The batter can keep for about a week under refrigeration because the milk in the batter will spoil.

Of course, ANY milk product or milk based product needs refrigeration
Fresh milk and any sterilized or tinned milk once it has been opened.
Refrigeration can cause the fat in breast milk to separate and rise to the top, making it easier to see and remove before feeding the baby.
Kept under refrigeration, milk should not spoil at least until after the expiration date on the top of the bottle or carton. Usually a week to 10 days, tops.
Fresh, pasteurised or extended shelf life milk has to be refrigerated because the processing does not remove all spoilage bacteria from the product. Refrigeration slows down the growth of spoilage bacteria and ensures that the product stays fresh longer.UHT treated or sterilised milk has a long shelflife and does not need to be refrigerated before being opened. This is because all spoilage bacteria is destroyed during the processing (typically a very high temperature for a short time). Only once opened will spoilage bacteria contaminate the product and start growing.
Refrigeration will slow down the growth of bacteria in the milk, but not kill the bacteria. This will slow down spoilage.
