Grade of plastic and seal strength is important. I am no chemist, but most plastic containers color and warp over time. This is probably accelerated with the physiology and chemistry in tobacco. It is a living microenvironment with chemical reactions occurring - that is why aging works!
Cheap plastic probably does not work well. Expensive plastic is a waste when jars are so cheap.
