PLA has a very good lifetime in use 'on the shelf' it doesn't begin to breakdown until it is kept in the warm, wet, and dark though it has a relatively short lifetime in the direct sun of some many months so you would not want to make an inflatable back yard wading pool for your children... on the other hand it would likely last the summer splashing season then fall to pieces :)

All of the worlds PLA plastic needs could be met using a sustainable harvest of a small fraction of the sargassum seaweed that fills the Sargasso Sea! Just take care of the ocean pastures that cover 72% of this Blue Planet and we can make the planet great again! This trumps other ideas with ease ;) Yes, but how long will the plastic last on the pantry shelf? Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
