Which Industrial Bag Sealer Do I Need?
The best industrial bag sealer depends on the bag material, filled bag weight, required sealing speed, and whether the bag is open mouth, valve-style, gusseted, non-gusseted, pre-glued, or vacuum/gas flushed. For large open mouth poly bags, a continuous heat sealer or hot air bag sealer is often used. For pre-glued multiwall paper bags, a pinch bag sealer is typically the best fit. For small pouches and retail bags, continuous band sealers or vacuum bag sealers are commonly used.

Continuous Bag Heat Sealers
These types of industrial bag sealers, or band heat sealers, are built for reliable and automatic sealing of large open mouth bags of chemicals, salt, food, pet food, agricultural products, consumer products, military items, coffee, and more. They are ideal for both polyethylene and barrier film and are a perfect fit for those applications requiring that government regulations like MIL-SPEC and USDA packaging guidelines must be met.

Hot Air Bag Sealers for Large Poly Bags
Hot air bag sealers are typically used for sealing non-gussetted, pillow-style polyethylene (PE) and polypropylene (PP) open mouth bags. However, they can be used to close and seal any pre-formed, non-gusseted, poly bags using hot air. These types of poly bags are used for packaging a wide range of products including fertilizer, pool salt, ice melt, industrial chemicals, compost, soil, etc.
Variable speed controls match the sealer and conveyor speeds for consistent and steady sealing rates. This type of bag sealing equipment can be used as a stand-alone sealer, or as a part of an automated bagging system. They have less moving parts than the continuous bag sealers mentioned above.
Horizontal and Vertical Sealers: seal nearly any weight, size, height, and type of bags such as stand-up, pillow, bags on a wicket, and zippered bags
Fast: up to 120 fpm or around 20 bags per minute
Seal Directions: all hot air bag sealers are available in right-to-left or left-to-right configurations
Seal Thicknesses: 20+ mils
Electrical: 110 or 220 volt / 1 phase / 60 cycle
Compressed Air: None required - the sealers use ambient air to seal bags
Options Include: painted steel, stainless steel for corrosive environments, motorized pedestal, touch screen interface

Pinch Bag Sealers
These heavy duty machines close pre-glued, multiwall paper bags containing products such as food additives, pet food, pesticides, fertilizers, and more. A patented breakaway design eliminates costly downtime due to bag jams and provides easier access for cleaning. As a filled bag moves along a conveyor, the bag top is manually or automatically formed and fed into the entrance guide of the pinch bag sealer. V-belts then convey the bag top through the closer where hot air is forced against the adhesive to activate it. Then the bag passes through a series of compression rollers to compress, fold, and set the adhesive.
Bag Types: stepped end, multi-wall PBOM open mouth paper bags with pre-applied glue strip
Fast: up to 75 fpm
Seal Thicknesses: 20+ mils
Electrical: Electric (NEMA 12): 230/380/460V-3PH-60Hz, 24 VAC
Compressed Air: 7 cfm @ 90 PSI
Options Include: left-to-right operation, reverse fold - rear direction, extended infeed for automatic systems, powder coat finish or stainless steel wash down versions

Seal Bags or Pouches Weighing 2 oz. - 15 lbs.
Continuous Band Sealers
Continuous band sealers provide fast, precise, and strong seals for small bags and pouches that are fed through a packaging line by hand or automatically by conveyor. They provide the highest level of seal integrity on any heat sealable and high density stand-up, gusseted, pillow, wicketed, and zippered bags.
Choose from a wide range of band sealers that fit your packaging line process:
- Standard Band Sealers: Seal a wide range of products packaged into small open mouth heat sealable bags. These machines can be customized to meet your requirements.
- Heavy Duty Band Sealers: These high-speed sealers seal products in high density / thicker bags usually weighing more than 2 lbs. that require extra strong seals at a fast rate.
- Validatable Band Sealers: These sealers are used by food manufacturers, as well as by the medical, pharmaceutical, nutraceutical, dental industries to validate a consistent seal integrity.
- Semi-automatic Band Sealers: Automatically convey bags and stand up pouches through these sealers or have multiple people hand feed this sealer.
- Tabletop Band Sealers: These types of sealers deliver high quality bag sealing for packaging lines with lower bagging rates.

Vacuum Bag Sealers with Nitrogen Gas Flush
Vacuum sealing extends shelf life, protects against corrosion, and reduces the final volume of filled bags for more compact packages. This type of bag sealing equipment is used to hermetically seal many different types of heat sealable, high density bags and pouches at rates up to 20 bags per minute. They create a high quality, vacuumed, gas flushed seal.
- Vacuum seal bags and pouches containing coffee, snacks, baked goods, electronics, medical devices, nutraceuticals, fresh food, dried food, produce, meat, and more.
- Nitrogen gas flush systems can be added to vacuum sealers for modified atmosphere packaging (MAP) that increase protection, freshness, and corrosion resistance for moisture sensitive products like coffee or electronics.
- Use validatable vacuum sealers for medical device applications that require validation for all packaging steps.

Ultrasonic Bag Sealers for Valve Bags
Ultrasonic bag sealers are incorporated into the framework of most valve bag filling machines.
Spout Integrated Ultrasonic Bag Sealer
This type of bag sealing equipment is a specially designed valve bag sealer that completely eliminates the puff of dust that is commonly emitted from filled valve bags as they are discharged from the spout of the filling machine. It is commonly used when packaging food and chemical products and provides a hermetic seal that ensures a highly sanitary finished package preventing valve leakage and moisture or contaminant intrusion through the valve sleeve.
Seal rate: up to 3 bags per minute (70 feet per minute continuous seal speed)
Bag types: thermoplastic lined paper and plastic valve bags
Control air: 80 PSI
Electrical: 220 Volt / 1 Phase / 60 Cycle

Industrial Bag Sealer FAQs
What is an industrial bag sealer?
An industrial bag sealer is a machine used to close and seal filled bags or pouches in a packaging line. Depending on the bag material and application, it may use heat, hot air, compression, vacuum, gas flush, adhesive activation, or ultrasonic sealing.
What type of bag sealer is best for large poly bags?
Large open mouth poly bags are commonly sealed with continuous bag heat sealers or hot air bag sealers. The best choice depends on bag style, film thickness, production rate, and whether the bag is gusseted or non-gusseted.
What is the difference between a continuous band sealer and a hot air bag sealer?
A continuous band sealer uses heated sealing bands and pressure to create the seal, while a hot air bag sealer uses heated air to soften and seal compatible plastic bag material as the bag moves through the sealer.
When should I use a pinch bag sealer?
Pinch bag sealers are used for pre-glued multiwall paper bags. The sealer activates the adhesive with heat, folds the bag top, and compresses it to create a closed seal.
Can industrial bag sealers be integrated into an automatic bagging line?
Yes. Many industrial bag sealers can be integrated with bag fillers, conveyors, bag top reformers, printers, checkweighers, metal detectors, palletizers, and stretch wrappers.
Do vacuum bag sealers work with nitrogen gas flush?
Yes. Vacuum bag sealers can be configured with nitrogen gas flush for modified atmosphere packaging, commonly used for coffee, food products, electronics, nutraceuticals, and other moisture- or oxygen-sensitive products.
