Milk bag
A milk bag is a flexible plastic pouch used to package milk and is used in some areas instead of a hardened milk jug. Usually one of the corners is cut off to allow for pouring, and the bag is stored in a pitcher.
A typical milk bag contains approximately 1 L (1.8 imperial pints) of milk in South America, Iran, Israel, and continental European countries, while in Canada they contain 1+1⁄3 L (2.3 imp pt), and in India, 0.5 L (0.9 imp pt).
In the Baltic rim countries and some Eastern European countries, similar bags may also be seen used for packaging yogurt or kefir.
