It might interest you to contact some Uk charities who are using China and some other third world countries to supply them plastic bags at next to nothing prices these certainly are being packed in small polythene envelopes in sweat shops. They would not be able to do the price otherwise.
Scope Shops - Croydon, England
British Heart Foundation Shops - Northampton England.
Peoples Dispensary for Sick Animals Shops Telford England -
I am sure they will say they are supporting the local economy
(and their profits).
My relatives happen to do home work for these organisations.
You might also care to seek a FREE video from CAFOD in respect to fair pay for the poor. They are in South West London England.
Good Luck in the search of pictures.
