Which I couldn't get from your Brief word file - that is
How the Bag looks like ?
Is it a Top sealed Stand up Pouch ? made of Poly(LD) ?
or Top & Bottom sealed general Pillow Pouch.
I need these information and any example of the Bag you are looking for..
to create concepts on actual mockup base with Matte & Gloss effects
and other treatment.
You see Packaging designs are successful when those are created considering
all technical aspects of final output.

Waiting for the informations......
