What we do
Snack food packaging depends on a continuous supply of high-purity nitrogen to displace oxygen, prevent rancidity, and protect product integrity for chips, jerky, nuts, popcorn, and other shelf-stable snacks. Gas Generation Solutions designs on-site nitrogen generators for snack food manufacturers, co-packers, and private label facilities. Our systems produce nitrogen at purities from 95% up to 99.9995%, reducing gas costs by up to 90% compared to delivered nitrogen. Gas Generation Solutions has been in business since 1979. Our USA-built systems ship across the United States, Mexico, and Canada. For the broader packaging science, see our MAP nitrogen page or the food grade cornerstone.

Applications
How nitrogen is used in snack food packaging
A correctly sized on-site generator supplies every nitrogen point of use in the plant from a single source: every packaging line, every bulk handling station.
Oxygen displacement
Flushes the headspace of bags, pouches, and canisters before sealing. Removing oxygen extends shelf life and preserves taste, color, and texture.
Crush protection
Creates the familiar pillow fill in chip bags that cushions fragile product from breakage during stacking, shipping, and retail handling.
Rancidity prevention
High-fat snacks (nuts, jerky, chips, chocolate) oxidize into rancid flavors in air. Nitrogen flush prevents lipid oxidation and holds flavor through retail shelf life.
Moisture control
Dry nitrogen displaces humid ambient air, preserving snack crispness and preventing caking in powdered or seasoned products.
Bulk ingredient blanketing
Totes, hoppers, and silos for oils, seasonings, and finished product use nitrogen blanketing during storage and transfer.
Package integrity testing
Some lines use nitrogen-based leak detection to verify seal quality on finished packages.
One generator, plant-wide supply. A properly sized on-site system feeds every packaging line and every bulk handling station from a single source. One generator replaces the complete delivered-nitrogen supply chain.

Sized to the full product mix. We size the generator to the plant’s entire SKU lineup rather than a single line. New products and new lines slot into existing capacity rather than triggering a new gas contract.
Purity & rancidity
Two purity tiers for snack. Lipid oxidation slowed by an order of magnitude.
Nitrogen purity
99.5% for most snacks, 99.9% for premium and extended shelf life
Snack food packaging runs at standard food-grade nitrogen purities measured as percent N₂ with the balance as residual oxygen in parts per million.
5,000 ppm O₂
Typical for most snack packaging: chips, pretzels, extruded snacks, jerky, nuts, and similar shelf-stable products.
1,000 ppm O₂
Extended shelf life programs, high-fat premium products, and tight code-date requirements.
Rancidity prevention
Lipid oxidation slowed by an order of magnitude
Rancidity is lipid oxidation: unsaturated fats react with atmospheric oxygen to form short-chain aldehydes, ketones, and free fatty acids. These compounds are what consumers taste and smell when a product goes off. Light and heat accelerate the reaction, but oxygen is the required variable.
Residual O₂ in pack
Typical target for standard snack applications. Achieved at the moment of seal under nitrogen flush.
Premium target
High-fat premium products and extended shelf life formats. Verified with an inline oxygen analyzer at the packaging machine.
Shelf life extension
Versus air-packed equivalents. Color, texture, and aroma hold through the intended code date.
Equipment compatibility
Built for every major snack packaging OEM
Our nitrogen generators supply snack packaging equipment from every major OEM. Each machine has its own inlet pressure, flow, and purity spec; we review the spec sheet, match the generator output, and confirm compatibility before quoting.

Service life
$15,000 to $200,000+ system price range for snack plants.
Delivered nitrogen carries compounding costs: gas charges, cylinder or dewar rental, hazmat fees, delivery surcharges, and 2 to 8% per day boil-off from idle liquid tanks. On-site generation eliminates all of them. Recurring cost is electricity for compressed air plus routine filter changes. Over a 20-year service life, cumulative savings on a mid-size snack plant commonly reach several hundred thousand to over a million dollars.
Food safety & shelf life
2 to 4x shelf life with consistent gas supply
Nitrogen used in snack food packaging is food-grade inert gas, listed as Generally Recognized As Safe under FDA 21 CFR 184.1540. It prevents oxygen-driven spoilage by displacing atmospheric oxygen from the pack headspace.
- Lipid oxidation in nuts, jerky, chocolate:slowed across the distribution chain
- Crush protection:pillow fill cushions chips, crackers, and extruded snacks in transit
- Moisture migration:dry nitrogen prevents caking in seasoned and powdered formats
- 2 to 4x shelf life:vs air-packed snacks, depending on fat content and code date
Maintenance
Three filter changes a year, no service contract required
Snack plant nitrogen generators require minimal routine maintenance. Plant maintenance teams perform filter changes themselves. Annual filter cost is typically a few hundred dollars depending on system size.
- Every 3 months:water and dirt filter change
- Every 6 months:oil filter change, valve and safety device inspection
- Every 12 months:charcoal final filter change
- Sealed sieve beds:no top-off required under normal operation

Frequently asked
Questions about snack food packaging nitrogen generators
What purity of nitrogen is required for snack food packaging?
Snack food packaging runs at 99.5% to 99.9% nitrogen purity (1,000 to 5,000 ppm oxygen). Most applications (chips, pretzels, extruded snacks, jerky, nuts) run at 99.5%. High-fat premium products and extended shelf life programs push to 99.9%. Snack food does not require purity higher than 99.9%. Residual oxygen inside the finished pack, not feed gas purity above 99.9%, drives shelf life. Our generators are capable of any purity from 95% up to 99.9995% for specialty applications.
Which snack foods benefit most from nitrogen flush?
All shelf-stable snacks benefit from nitrogen flush, but high-fat products see the largest shelf life extension. Nuts, premium jerky, chocolate, specialty chips, and seasoned snacks with oil-based coatings extend shelf life two to four times versus air-packaged equivalents. Low-fat items like pretzels and crackers gain less shelf life but benefit from crush protection and aesthetic pack pillow.
How does nitrogen prevent rancidity?
Rancidity is the oxidation of unsaturated fats by atmospheric oxygen, which produces off-flavor compounds. Nitrogen flush removes oxygen from the package at the moment of seal, reducing residual oxygen to 2% or below (under 1% for premium products). At those levels, lipid oxidation slows dramatically and flavor, color, and texture hold through the intended code date.
Can one nitrogen generator feed multiple packaging lines?
Yes. A single generator sized to total plant demand supplies multiple VFFS, HFFS, tray, pouch, and canister lines, plus bulk ingredient blanketing and leak testing from one source. This is more cost-effective than separate supplies at each line and simplifies expansion when new lines are added.
How much does a nitrogen generator for snack food packaging cost?
Systems for snack food plants typically range from approximately $15,000 for a small artisanal operation to over $200,000 for high-volume national-brand multi-line plants. Price depends on total flow rate, required purity, delivery pressure, redundancy requirements, and any integrated storage. Regardless of system size, the average payback remains 12 to 14 months.
How much nitrogen does a snack food packaging line use?
Consumption varies by line speed, bag size, and flush rate. Single-line artisanal co-packers typically use 100 to 500 SCFH. Mid-size regional producers use 500 to 3,000 SCFH. Large commercial multi-line plants use 3,000 to 15,000 SCFH. High-volume national-brand facilities often exceed 20,000 SCFH. Our free flow meter rental measures your actual consumption so the generator is sized to real demand.
How long does a nitrogen generator last?
Our systems are designed for 20 years or more of continuous service. Sealed sieve beds do not require replacement or top-off under normal operating conditions. Competing systems using flanged sieve beds may require sieve replacement every 8 to 10 years, which is a significant hidden cost over the life of the equipment.
