Doypack packaging machines for stand-up pouches

Rotary Filling and Sealing Technology for Flexible Pouch Formats

Automated and Flexible Packaging Process

Our Doypack packaging machines fill and seal pre-made stand-up pouches, zip-lock pouches and flat pouches fully automatically. The rotary filling and sealing machines are suitable for food, pet food, dietary supplements, coffee, powders, granules, snacks and chemical-technical products.

The Doypack rotary series processes different bag formats with high cycle rates and reproducible sealing quality. Depending on the application, multihead weighers, linear weighers, screw feeders, liquid fillers or other dosing systems can be integrated.

Thanks to short changeover times, modular expansion options and intuitive operation, the systems are suitable for both medium-sized manufacturers and industrial production facilities.

The DEAP-8BT's 8-station system

The DEAP-8BT is a fully automatic rotary machine for filling and sealing pre-made stand-up pouches, Doypacks, and flat pouches, as well as, optionally, zipper pouches.

The 8-station system guides the pouches step by step through the entire packaging process—from automatic pouch retrieval to opening and filling, through to secure sealing and discharge.

The eight process steps:

  • Bag pickup: Automatic retrieval from the bag magazine.
  • Zipper opening (optional): Opening existing zipper closures.
  • Bag opening: Opening and erecting the bag using an air supply.
  • Opening check: Verification of correct bag opening; optional inert gas flushing.
  • First filling station: Product-specific dosing and filling.
  • Second filling station (optional): Additional dosing or use for further process modules.
  • Heat sealing: Thermal sealing of the bag opening.
  • Cold sealing and discharge: Cooling and stabilizing the seal, as well as discharging the finished bag.

Thanks to various dosing systems, the machine can be adapted to powders, granules, liquids, and pasty products. The exact configuration, station layout, and capacity are determined on a project-by-project basis.

Technical details

The DEAP-8BT Doypack packaging machines process stand-up pouches, zip-lock pouches and flat pouches fully automatically. The machines are suitable for food, pet food, dietary supplements, coffee, powders, granules and other bulk goods, and can be customised to suit the specific application.

Frequently asked questions about our rotary filling and capping machine (rotary machines)

A rotary machine operates with a rotating carousel system on which prefabricated bags are automatically opened, filled, and sealed—quickly, efficiently, and compactly.
Our rotary machines are particularly popular for medium to high production volumes.

Rotary filling systems are suitable for stand-up pouches (Doypacks), flat pouches, and pouches with zippers, spouts, or Euro holes. Special formats are also possible.

Rotary machines require less space, achieve high cycle rates, and can be flexibly combined with dosing systems—ideal for processing different products and formats.

Yes, our rotary filling and capping machine also processes recyclable mono films, compostable bio bags, and paper-based packaging.
You can find suitable sustainable packaging in our Castelli Greenline series.

Typical uses include food (powders, snacks, pastes), pet food, cosmetic products, cleaning agents, and supplements. With the right dosing system (multihead weigher, auger filler, etc.), almost anything is possible.

Rotary filling and sealing machines guide pre-made pouches through the packaging process via stations arranged in a circular pattern. In horizontal systems, the pouches are transported along process stations arranged one after another. Both types of machines can automatically open, fill, and seal pre-made pouches. Which design is better suited to your application depends, among other things, on the product, bag format, dosing, desired throughput, and the requirements of the packaging process.

Depending on the application, the DEAP-8BT series can be equipped with various add-on components. These include, among others, weighing and dosing systems, labeling systems, inkjet and thermal transfer printers, nitrogen flushing, and double or triple bag magazines. Additional labeling and feeding solutions can also be integrated, depending on the packaging process.

Here you’ll find our compatible weighing and dosing systems: Weighing & Control Systems

Yes. The DEAP-8BT series can be optionally equipped with a nitrogen flushing system. Depending on the product and the packaging process, nitrogen is introduced into the bag. The specific configuration is tailored to the respective product and the requirements of the packaging process.

The appropriate machine model depends primarily on the bag size, product, dosing system, and desired output. The DEAP-8BT processes standard formats at up to 45 bags per minute; the Duplex model is designed for higher output of up to 80 bags per minute; and the DEAP-8BT XL enables the processing of larger bag formats up to 300 mm in width and 470 mm in length. Actual output depends, among other factors, on the product, bag format, and dosing system.
