Nylon tea bags

The latest marketing push for tea will be nylon mesh teabags (according to the Patent Search Blog). The idea is that nylon teabags allow the tea leaves to unfurl within the bags (which paper-based bags don't) and experts claim that the taste is considerably improved. However, this will increase the cost of the teabag; apparently an average paper teabag 2 pence whereas a nylon one will cost about 8 pence - a 300% price increase - and the bags are also not biodegradable. It appears that 96%of tea drunk in Britain is in the form of teabags. Maybe we should return to using a teapot and loose tea for the sake of our health, our wallets and the environment!
