Abstract
An apparatus for forming a seal (40-44) along an edge portion of a flexible package (10) that is made from a sheet of flexible material (137) includes an elongated film folding member (102) and at least one heating and/or sealing member (104), the at least one heating and/or sealing member (104) extending along a first heat/seal axis parallel to a lengthwise axis (108) of the film folding member (102). A first engagement end (112) of the film folding member is adapted to contact a portion of the sheet of flexible material (137) during a sealing process and the at least one heating and/or sealing member (104) is adapted to heat the portion of the sheet of flexible material (137) during the sealing process such that the contact between the first engagement end (112) and the portion of the sheet of flexible material creates the seal along the edge portion of the flexible package (10).
