Open mouth bagging machine
An open mouth bagging machine fills pre-made open-mouth bags in almost any style and material. TiERMAX baggers can be fitted with net or gross weighing and fed by the doser that suits your product: gravity, belt, screw or twin screw feeder.
Our automatic open mouth bagger, rated at up to 5 bags per minute for difficult powders, has two key features: a deaeration probe that removes trapped air from the bag during filling, and a sealed filling spout that closes the bag mouth tightly throughout the fill cycle. Together they let the machine handle slow-flowing, aerated powders cleanly and produce firm, compact bags.

Semi-Automatic Open Mouth Bagger
The semi-automatic machine handles granules, powders, pellets and flakes and is popular in flour milling and chemical plants. It fills bags of about 10 to 110 lb (5–50 kg) accurately, and changing bag sizes takes little effort. It comes with gross or net weighing and belt, gravity or screw feeding. Add a bag closing line (sewing, heat sealing or gluing) to make it a complete system.
Universal Automatic Open Mouth Bagger
The universal machine fills and closes open-mouth bags automatically. Its modular structure and step-by-step bag transport handle nearly any bag and product and connect to any closing system. A pendulum motion of the bag grippers during filling and discharge keeps speeds high, and bags move through each station to final closure without operator handling.

Open Mouth Bagger for Woven Polypropylene Bags
A dedicated version handles woven PP (raffia) bags used for fertilizer, feed, sand and minerals, with sewing or pinch closure.
Completing the Line
Filled bags travel to a check-weigher and palletizer. For high volumes from film, see the form fill seal bagging machine.
Frequently Asked Questions
It is an industrial packaging machine that fills pre-made open-mouth bags with powders, granules, pellets and other bulk materials, weighs them and passes them to sewing, heat sealing or pinch-top closing.
The bag is placed on the fill spout, filled to the target weight by the doser, and transferred to the closing station. Weighing control, bag settling, deaeration and automatic bag handling can be added.
Chemicals, fertilizer, food ingredients, feed, plastic pellets, seeds, grains, minerals and agricultural products. The filler is matched to flowability, bulk density, particle size and dust behavior.
Paper, PE, woven polypropylene, laminated, flat and gusseted bags, typically from about 10 to 110 lb (5–50 kg).
Automatic bagging is faster and more accurate, reduces manual labor, improves safety and dust control, and integrates with conveyors and palletizers.
Screw and twin screw feeders, gravity fillers, belt feeders and net or gross weighers. The doser is chosen for the material, accuracy and rate required.
Yes. Sealed fill spouts, deaeration probes, dust extraction connections and enclosed filling areas keep dust down when bagging fine powders.
Consider product characteristics, bag size and material, required rate, fill accuracy, dust control, closure type, automation level and downstream integration.
