The special pouch is manufactured exactly the same as all the other sealed-rim pouches, from a composite film on a roll. Manufacturing of the pouch is carried out on the pouch manufacturing machine. The feature here is the type of pouch manufacturing. Through specific design before sealing, pockets, envelopes, etc. can be attached to the pouch. For example, kangaroo pouch. After sealing the vertical and bottom seams, the finished pouch is transferred to the rotary  filler for filling. Here, sealing the crown is also carried out, either thermally or optionally using ultrasonic. The most common application for this type of pouch is as a flat pouch or double pouch.
