Contemporary packaging design research

I have designed the apple packaging and am reasonably happy with the colours, stock  and shapes.  I am struggling slightly on which fonts, sizes and layout to use on the packaging.  Some of it looks clumsy and cluttered.  So I have decided to go back to the drawing board and look at some Contemporary packaging which appeals to me:

Brown definitely connotes sustainable!  The 'USE ME' is strong.

The simplicity of these labels really appeal to me.  I was avoiding Serif fonts for the rest of the descriptions as the main logo is serif however I think this works and adds a certian history and authenticity

The layout of the description which us aligned left in the left corner is visually appealing.http://www.packagingoftheworld.com/2009/12/jamie-oliver.html
