In the 1970's, milk was available to buy in these plastic sachets shown above. A quick snip of the top corner, either using scissors or your teeth, and you had access to the contents. In addition, you could get plastic holders to place the sachets into which were designed to make it easier to pour and store at home. People used sachets a lot for their breaks at school and workplace.
I remember at Craigie High School we used to chuck them at each other in the playground. The idea was to catch the sachet without it bursting. Needless to say there were occassions when the bag did burst, resulting in sour blazers!!
