Abstract
A form-fill-seal method and apparatus for wrapping food items. A form-fill-seal apparatus includes a shaped seal member and a shaped cutting knife, for example, a curved seal member and a curved cutting knife. Wrapping film is provided to the form-fill-seal machine, e.g., as a flat shape, and formed into another shape. A food item is fed into a pocket of the formed wrapping film. A shaped seal is formed in the wrapping film along a first end of the food item using the shaped seal member and cut adjacent to the shaped seal with the shaped cutting knife.
