Clever Milk...

This is Sainsbury's new idea for packaging their milk. This is a bag that would hold milk, and then you could decant it into...well some other milk holding device. The bag would use 75% less packaging, and be more environmentally friendly, though not all local authorities collect bags as part of their recycling schemes. I'm not really sure about this...I mean its all very well and good, but if the milk is going to cost the same then this improvement is just making Sainbury's more money...
