As a packaging designer I come across lots of different packaging from around the world. Most of the time, I design packaging for US-based companies, which have their packaging standards. The FDA and USDA regulate food packaging guidelines relating to nutrition, net weight and product claims. The standards in Europe are less familiar to me. One device I’ve seen on packaged products is a little ‘e’ symbol alongside the net weight statement. I never knew what it stood for and was curious. I finally did discover its name and purpose.
It’s called the Estimated Sign.
