    Abstract: Provided herein are apparatus and methods for film sealing dies, and in particular, to apparatus and methods for film sealing dies in form, fill and seal (FFS) processes. An apparatus for sealing plastic film materials includes a heating mechanism, the heating mechanism including a heating lip (110) arranged such that when a plastic film (120) is contacted with the heating lip (110), the heating lip (110) forms a hot seal on the plastic film (120); and a cooling mechanism, the cooling mechanism comprising a gas jet duct oriented to contact the hot seal on the plastic film (120) at a contact angle between 0 and 60° such that the hot seal formed on the plastic film (120) is cooled to a temperature of less than or equal to 40° C. in less than or equal to 5 seconds to form a sealed plastic film.
