Found a very simple and great concept for a take out packaging in thedieline.com:
"Using banana leaves as a new material to create new ecological packages for take away. Banana leaves are a product which exists in many regions around the world. This material has a wax-like surface which is ideal for wet and greasy foods. It is flexible and therefore can be adapted to many types of packaging. The leaves last long after they are cut o ff the trees. The packages are cut to form using die cutting technology. No glue is used. The unique qualities of this material allow packages to be opened simply by tearing the banana leaf along its natural perforation.
Today the majority of disposable goods are wrapped in man-made, often petro-based materials that usually last far longer than the items they protect. With many companies spending millions on R&D searching for more sustainable alternatives, an Israeli designer named Tal Marco has taken a decidedly low-tech and refreshing approach to package design with his use of natural banana leaves.
Banana leaves are highly flexible, easy to open and have a naturally waxy surface that is ideal for food applications. Although not a completely novel idea, Marco's design uses die-cut leaves that can be folded into numerous forms and lend themselves well to many retail applications. His design was showcased in Designboom's "Dining in 2015" design competition and the concept puts many of the most "environmentally friendly" packages on the market today to shame.

Green Marker
found another "green concept" design which by yuruliku, not really environmental friendly, but very lovely, simple and beautiful.
