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, or as an alternative to it. 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).[1]

In the Baltic rim countries and some Eastern European countries, similar bags may also be seen used for packaging yogurt or kefir.

Benefits

edit

For producers, it is easier to vary portion size when sealing bags than cartons, as well as lowering the cost of packaging. Milk bags also take up less space in the garbage. For consumers, bags typically allow for smaller portion sizes. This theoretically reduces the risk of spoilage, as well as the space and location of storage in the fridge.[2]

Recycling

edit

While milk bags use less plastic than standard plastic bottles or jugs, empty bags are often not accepted for recycling when mixed with other plastics.[3] In Canada, where recycling services are municipally or regionally managed, milk bags may not always be recycled. In some municipalities milk bags are required to be discarded as garbage[4] and in others they are recyclable.[5]

By country and region

Canada

Neilson Dairy milk bags and cartons in Ontario, Canada

In Canada, milk was packaged in heavy, reusable Imperial unit glass milk bottles, cardboard cartons and plastic jugs until 1967, when DuPont, using European equipment, introduced plastic bags to store and sell milk; these bags gained widespread acceptance due to 1970s Metrication in Canada, when bottles, jugs, and cartons had to be redesigned and manufactured in metric units; milk bag packaging machines could easily be resized.[6][7][8]

The consumer public preferred plastic jugs for years, but largely accepted the new containers in parts of Ontario, Quebec and the Maritimes in the 1970s.[9] Regulation in Ontario that required retailers to collect a deposit on milk jugs, but not bags, also motivated the practice.[10]

Milk bags are sold in parts of Ontario, Quebec and the Maritimes, but no longer widely sold in western Canada, in Newfoundland and Labrador, or the territories.[9]

Israel

Israeli milk bags

In Israel, milk in a bag is the most common type of packaging for milk. They became the standard form of milk packaging in the 1960s, with the discontinuation of glass bottles. In Israel, the milk bag is a regulated product, which means that its price is controlled by the state. Therefore, there are price differences between the milk bags and the other alternatives available for marketing milk — plastic bottles or milk cartons. Due to the price differences, a relationship was observed between the socioeconomic status of the consumer and the type of milk container that they customarily purchased. The higher the socio-economic status of the purchaser, the more likely they are to buy milk in cartons rather than in bags, despite the higher price of cartons. Based on these differences, Blue Square Network created a way to measure the socioeconomic status of an area based on the sales ratio of milk cartons versus bagged milk. The higher the ratio of the former to the latter, the higher the status of the region in Israel.[11] For religious Jews, opening a bag of milk can be considered problematic on Shabbat, because the action requires cutting. Eli Yishai, Israel's former minister of internal affairs, used empty milk bags in the Knesset as props to complain about price-hikes in the cost of milk.[12]

South America

Milk bags are also commonly used in Colombia, Ecuador, Argentina, Bolivia, Brazil, Chile, Paraguay, Peru, and Uruguay.[13]

United Kingdom

edit

In the United Kingdom, Sainsbury's began a pilot experiment on distributing milk in bags in 2008 in conjunction with Dairy Crest.[14] It was originally targeted at 35 stores at the same price as a regular 2-imperial-pint (1.1 L) plastic bottle of milk.[15] The product was expanded nationwide in 2010, at which point the bags retailed at a discounted price compared to traditional containers,[16][17] but stopped in early 2015.[18]

United States

edit

DuPont introduced milk bags to American schools in 1989; by 1993 three million pouches a day were being served in 24 states.[19] However, the popularity of them waned. There appears to only be one verified school district, in Omaha, NE, using bagged milk as recently as 2015.[20]
