Open Mouth Bag Fillers

Open Mouth Bag Filler

Open mouth bag fillers weigh, fill, and seal different types and sizes of bags and containers with dry bulk solids and products like powders, flakes, granules, and irregular shaped pieces. The filled bags and containers usually fall in the 20 lb. - 110 lb. weight range. There are many different types of open mouth bag fillers including manual, semi-automatic, and automatic versions with filling speeds up to 24 bags per minute with 50 lb. bagging machines being the most popular.
