The Bio Sandwich wedge offers simple and easy erection and loading, and although for day fill use (due to the clever closure used), they extend the shelf life compared to other products in the market. The Bio Sandwich cartons are produced in 400mic Kraft board; we apply a natural coating on the inside to act as a barrier against grease (such as butter or mayonnaise). The film window is produce in PLA and so enabling the whole carton to be compostable.
