Help with homework - food packaging

[MrsMom]

Homework this week - On food packaging what does the 'e' mean after the weight of the product. Any ideas?
Thanks

I always thought it meant that's the net weight of the food - i.e. just the food, not the packaging. Am ready to be corrected though...

whose homework is it we're doing?

I've just noticed it's on toothpaste, shampoo etc as well.
My daughter is only in year 1!! The teacher said she will give a sticker to anyone who finds out. Guess she doesn't know herself!

Found on the Birdseye website, here is your answer:

"Net weight
This is the weight of the food minus all the packaging. The e mark after the weight means that we've packed the food to meet the average weight legislation - a set of rules that ensures that all manufacturers' product weights have a common standard. "

here at the food standard agency
gosh, that took me 20 minutes to find!

Thank you SO much everyone. Stickers all round!
