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.

To give you a good idea about the types of open mouth bagging machines and systems that are available, we have included descriptions, images, and videos from past installations. Learn more about filling plastic and paper bags with products like deer corn, seeds, cattle feed, fertilizer, wood pellets, flour, mixes, sugar, sand, pellets, chemical powders, and more. We have tried to include as many details as possible including how fast you can fill bags, how each machine operates, and how bag closing works.
This fertilizer bagging system is used to fill poly bags with granular, free-flowing fertilizer. It includes a specially designed discharge stand and stainless steel hopper for Buckhorn CenterFlow seed boxes, a stainless steel digital gross weigh bagging scale with pneumatic bag clamp, a stainless steel mesh belt bag closing conveyor, and a hot air bag sealer.
The same type of system could be used to bag other types of free-flowing products like animal feed, plastic pellets, grains, seeds, wood pellets, and more. Multiple bag filling recipes are stored and easily swapped out via the digital scale controller.

Rice producers face several challenges when it comes to bagging and packaging their product. Manual bagging processes can be time-consuming, labor-intensive, and prone to errors. To overcome these challenges, a USA-based rice producer sought an automated packaging system that could increase production efficiency, reduce labor costs, and improve bagging accuracy. In this case study, we’ll examine how the company successfully implemented the system, resulting in significant time and cost savings.
The Grain and Corn Bagging System combines product storage, filling, and bag closing into one system. Efficiently fill and close 30-50 lb. paper and poly-woven open mouth style bags.
The system has been engineered for bagging deer corn (whole corn), feed, seed, and other grains. The manual, or mechanical, bagging option includes automatic weighing. The system is upgradeable to a higher packaging speed with the addition of a high-speed bag sewing system to quickly close the bags. Additional options are available including hand held bag sewing machines, bag flattening conveyors, and bag stacking systems.
Tinsley Equipment Company recently performed a test run for a new feed producer for filling 25 Lb. bags with horse pellets.
These type of supplement pellets were made of coastal hay and measured about ¼-1/2” in diameter and about 1 inch long. The producer’s family farms different types of coastal hay and Bermuda grasses and wanted to learn more about the bagging and packaging process.
Horse pellets (or hay pellets) used for feed supplement
To run the test, Tinsley Equipment Company set up a 25 cubic foot bagger supply hopper, a digital gross weigh bagging machine with a pneumatic bag clamp, a temporary box platform under the scale to support the filled bag, and then a table for manual bag top folder over and handheld sewing. Closed bags were manually transported and stacked on pallets resting on a truck trailer. Finished pallets were manually wrapped and secured to the trailer before transporting them to a feed store for final sale.
Lot / batch code and date printed on bottom part of bag after passing print head
This inkjet code printer was put to the test in an animal feed and minerals packaging line. Multi-wall open mouth paper bags, filled with animal feed are sewn shut. Then, they pass in front of the code printer on a conveyor before robotic palletizing. As each bag passes the code printer, a lot code and date are printed on the bottom part of the bag. Each of these unique codes helps to identify when the batch of product was produced and packaged.
The automatic bag placer machine picks up, hangs, and clamps an empty open mouth bag onto a bagger before product is discharged into a bag. Up to 20 bags per minute are possible and it works with both new / existing net weigh and gross weigh bagging scales. With this type of automation, one full-time operator can be removed from the bagging system.
Packaging system fills open mouth paper bags at a rate of 4-6 bags per minute with granular and powder products, such as zeolite and guar gum.
The system repackages products from big bags, also called bulk bags or Super Sacks®. It includes a forklift loaded bulk bag unloader with an extended frame to accommodate an open mouth bagging machine underneath.
Bagging system, bag sewing system, and bag handling conveyors
This bagging plant fills 40KG open mouth plastic bags with different types of livestock feed for poultry, pigs, dairy cows, sheep, and horses. It includes a high-speed bagging machine, bag handling conveyors, and a palletizing robot with automatic pallet dispenser and automated pallet wrapper.
Dry pet food bagging systems and machines automatically weigh and fill 1-50 lb. bags, pouches, containers, and multi-wall open mouth bags with different types of dry pet food. This includes dog food, cat food, rabbit food, hamster food, food for mice, and more.
Fill small bags, pouches, and containers that weigh 1 – 10 pounds or larger open mouth paper or poly bags that weigh 10 – 50 pounds, or bulk bags that weigh up to 4,400 pounds. All packaging machines have an accuracy of +/- 0.5-1% of target weight and can operate at different bagging speeds.
This commercial equipment is used for repackaging bulk dry goods stored in bulk bags, bins, totes, pro boxes, 40-50Lb bags, and more into small bags, pouches, and containers.
Examples of free-flowing bulk dry goods to repackage or re-bag would be food products such as rice, nuts, coffee beans, sprinkles, pasta, beans, candy, seeds, dog food, and cat food as well as products such as feed pellets, wood pellets, and plastic pellets.
This packaging and palletizing line fills craft paper bags with 25, 40, or 50 lbs. of livestock minerals and supplements. It includes a hopper, net weigh bag filling machine, high-speed bag sewing system, and robotic palletizer with 2 bag stack zones. It replaced an existing bag filling and packaging line at the feed service company that has been in business since 1946.
This milk powder bag packing machine fills 50 lb. open mouth bags at a rate of 2-3 bags per minute. It provides an accurate and dust tight filling process. The machine is designed to be quickly and easily disassembled for access to internal components when cleaning and sanitation is required.
