Abstract: Apparatus for forming bags of desired length from flattened plastic tubular stock material and subsequently sealing them at the open end thereof. The apparatus includes housing means having supporting means within the housing means for rotatably mounting a supply roll of the flattened stock material, with guide means in vertically spaced relationship to the supporting means cooperating with advancing means including a pair of rollers for engagement with the stock within the housing means in vertically spaced apart relationship to said guide means. Base means and heat sealing means form a pair of transversely extending seals. Dual cutting means cuts the bag to any desired length and a vertical slot between the seams is formed as a pouch for inserting a label to identify the contents. The apparatus also includes means to seal the open end of the bag with the contents therein.
