Open Mouth Bagging Machines

Open mouth bagging machines weigh and fill different types and sizes of bags and containers with bulk solids and products that are powders, flakes, granules, and irregular shaped pieces. The filled bags and containers usually usually weigh 20 lb. - 110 lbs. There are many different types of open mouth bagging machines including manual, semi-automatic, and automatic versions with filling speeds up to 24 bags per minute (50 lb. bagging machines being the most popular). Once the bags have been filled, they are usually moved through a bag sewing or sealer machine. Then, they are conveyed to a station, where the bags are palletized, stacked, and wrapped for shipping, storage, and sale.
