Seal, stitch, and sew shut many different types of large open mouth bags and small open top plastic bags at rates up to 20 bags per minute. Ultra-sonic bag sealer machines can be used to hermetically seal and close valve bags at rates up to 3 bags per minute.
View ( 16 ) Bag Sealers, Stitching, and Sewing Case Studies Below
Bag stitching can be accomplished using a portable bag sewing machine or a machine that is attached to a stand that is a part of a bag packaging conveyor system. Portable bag sewing machine can stitch shut 4 to 8 bags per minute and fixed sewing machines have stitching rates around 6 to 20 bags per minute.
Bag sealers, or heat sealing machines, close and seal paper or plastic bags and pouches at rates up to 20 bags per minute. Paper bag sealers pinch the bottom of the multi-walled paper bags with a pre-glued flap and heats them until the glue reaches a melting point. Plastic bag sealers seal poly-based bags using a hot air or rotary band sealer to close the bags.
The case studies below feature bag packaging systems that use some type of bag sealer, heat sealer machine, bag stitching, paper bag sealer, or poly bag sealer machine.
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.
Bag moves through a bag top reformer before sewing
This type of automation can eliminate the need for an operator to manually guide a filled bag into a bag closing system. It can handle production rates up to 15 bags per minute and typically comes with an automatic bag placer.
A snack food producer needed to increase production on one of its bagging lines for breading mix. The existing equipment was centrally located within their process, which made any upgrades or integrations challenging. The customer’s project requirements included a bag sealing machine that uses an ultrasonic sealer to hermetically seal valve bags. This way, the bags would be dust tight before dropping onto a conveyor below.
Auto Bagging and Palletizing System (click for larger image)
This auto bagging and palletizing system is designed to fill 50 lb. open mouth poly bags at a rate of 10 bags per minute. Free-flowing and dry bulk material flows from the 80 cu. ft. hopper into a net weigh gravity flow bagger that includes a vibrating feeder with gravity gate. The feeder doses a set amount of product into the internal weigh hopper.

Why is it important to vacuum seal coffee bags and flush them with nitrogen?
Vacuum sealing and flushing a bag with a gas like nitrogen removes most of the oxygen, making it difficult for aerobic bacteria to grow. This extends the shelf life and freshness of whole coffee beans and ground coffee. Many large grocery stores, retail coffee shops, or online retailers like Amazon, require that coffee producers use VGF/MAP for their packaging for resale. (VGF stand for Vacuum Gas Flush and MAP stands for Modified Atmosphere Packaging.)
Product is supplied to the bag weighing / filling system from a product supply hopper / bin located above the bag filling machine. The product is pre-weighed in a 1.0 cubic foot weigh hopper prior to dispensing into the bag.
The NWB, or Net Weigh Bagger, is used for bagging BBQ wood smoker pellets at a rate of 20 tons per hour into open mouth bags. It is a great solution to accurately fill bags to a set target weight of 25 – 60 pounds.
This wood pellet bagging equipment is used to fill and seal 20-110 pound paper or plastic bags with hardwood pellets that are used for smoking and grilling BBQ. It can also be used to bag wood chunks and chips. The typical system available for purchase includes a 37 -or- 71 cubic foot supply hopper, a mechanical -or- digital gravity fed bagging machine, bag closing equipment, and a palletizer.
