Hi : Here is a good web site to start getting some information on some of the properties of various types plastic containers. http://www.plasticbottle.com/techinfo/resin.html . While it does not go into the various chemical compositions of each them you could contact the manufacture for more information. It seems like all of them have strengths and weaknesses .
Though breakable I still like the idea of using glass to store my CS in. It may be that glass especially if it is made from recycled glass may have some problems . Does anyone know? Alan
