Dairy products
Milk
A food product that, due to processing technology, packaging material and method, is able to extend its shelf life from hours into weeks and months
Shelf-life of bottled fluid milk is reported to average between 10 and 21 days when stored at 4-8°C.
The shelf life varies depending on:
raw milk quality, processing conditions, microbial growth, packaging materials, exposure to light and temperature abuse.
The dairy industry able to achieve a 45-day shelf life through the use of ultrapasteurisation (UP) processes, while ultra-high temperature (UHT) processed products achieve a shelf life of three months to one year with no refrigeration.
Liquid packaging cartons

Combine paperboard with an additional moisture and product resistant heat sealable material
