Milk packaging machines can be manual or automatic. Manual packaging machines are relatively cheaper than their automatic counterparts. The automated machines will sometimes pack up to 200 milk packages per minute. When using pouches, they will move intermittently to stations where they are filled and then sealed before packing them for distribution. Automatic pouch filling machines can have single, double, or four-lane configurations.

An operator will load the preformed pouch onto the machine, and then a roller will transport it to a section where it is gripped. A proximity sensor will detect this pouch and load it to the vacuum loader. When you need the packaging printed, you can get a machine to do so before the pouch is moved to the filling section. After filling the pouch, a deflator will squeeze out all air from it before sealing it using a hot seal bar. This binds the sealant layers using pressure, heat, and time to make a strong seam.
