Vertical filling: Four-edge seal bag machine for the pharmaceutical industry (intermittent)


The pharmaceutical bag machine PPH produces flat bags and fills them with powder and bulk goods. The packaging film is printed in the machine and linearly transported to the three-edge sealing bag for further processing. The bags are delivered in the round motion machine, following by dosing with a 100% weight inspection as well as final sealing. The bags are fed to the downstream cartoning machine via a stacking station and are packaged specifically by format into folding boxes.

  • Modern construction in GMP-appropriate design
  • Connection to lines and fully automatic production
  • Separate monitoring of all quality-relevant process steps
  • Completely protected production room
  • The ability to manufacture product variants and patient-specific preparations
  • Integration of micro-dosing systems for bulk goods, powder and liquid
  • Fast product delivery through parameterized batch release
  • PPH – Production and filling of four-edge sealing bags for pharmaceutical products

    PPH produces and fills hermetically sealed bag packages for pharmaceutical powder and bulk goods.

  • PPH – Film web folding for production of bags

    Folding the film web.

  • PPH – Sensory inspection and filling in the round motion unit of the bag machine

    Functions in the octagonal round motion unit include transferring the bag, sensory inspection of the bag opening, dosing and subsequent weight inspection.

  • PPH – Cascade feeder for grouping the bag prior to passing it along to the cartoning machine

    After the weight inspection, the packages arrive in the grouping unit. Package stacks are created by the cascade feeder and passed along to the cartoning machine.

  • PPH – Transport of bag stacks to the cartoning machine for secondary packaging

    Transport and pushing over bag stacks into the product chain of the cartoning machine.

Machine features


Product packaging in bags plays an important role in product protection and in ensuring sterility. Sophisticated sealing and cutting components guarantee a high performance packaging process – from small to large format applications.

In-line printing

Products can be coded at various positions during the process. Film components or bag webs are printed with a batch code or information about the product quality. Harro Höfliger uses the popular systems thermotransfer, Inkjet or laser.


Sealing is one of the central processes when connecting several product layers. We apply several technologies for this process. Depending on the material characteristics, we use such applications as platen sealing, roller sealing (hot and cold), pulse sealing, ultrasonic sealing or thermal sealing.

Camera inspection

Position and location accuracy, products in the sealing area, color deviations, damage or soiling to the detection of particles using sensor technology: Powerful camera systems are essential in quality inspection.
