What's up with plastic in tea bags?

I stopped buying tea bags because either the boxes were wrapped in plastic or, even worse, each  tea bags was. Did you know that the tea bags themselves contain plastic, so they can't be composted?

According to the blog, Treading My Own Path, tea bag sheaths contain reinforcing plastic. Read Lindsay's post here: Plastic Free Tea. 

If you'd like to do something about this, join her campaign. Oh, and use loose tea, which tastes better anyway!
