This is the tea I use. Like Coffee needs to be stored in freezer, are there any storage restrictions for loose tea leaves also?
Tea needs to be kept away from heat, light, air, and moisture. The best way to store tea is at room temperature in an opaque, airtight container.
Your container should not be plastic, because odors from previous uses (even if its only been used solely for tea) could contaminate your current tea.
Do not store tea in the freezer or refrigerator. Opening and closing of the door causes rapid humidity changes that cause moisture to seep into the container and degrade the flavor of the tea.

Personally, I would go for one with a twist or latching cover rather than a slip cover, just to ensure that it's airtight.
In my opinion the best way is if you take the tea into a hermetically sealed box (that can be found in almost every supermarket), the tea won't lose their smell and taste in a long time. But don't forget everything will go bad sooner or later.
The freezing isn't recommended, because the micro ice cristalls do harm the fibers of the foods, that's why the freezing makes more tastles the frozen foods (but not very much). This is the reason why the meets can be frozen only once.
You must buy teas from some reputed shops .It should be placed in a very dry place with out any strong smells.Green tea requires more preservation than other teas If you keep it with vacuum sealer then it will be preserved for more days.
