I moved to US recently from India and I am looking for Plastic jars for storage,
Run a search for something called "Snap-Ware." Tough, durable, airtight, and very stable plastic. It's even recommended by David Suzuki as a storage medium. Granted, a lot of people consider him alarmist, but he knows his stuff when it comes to bisphenol-A and neoestrogens. I've been using the same Snap-Ware containers for 13 years, and not one has broken, discolored, degraded or had its seal fail.
