The only package leak detector that shows you the leak and where it is — in a single test. FlexPak’s bubble emission chambers locate exact defect points in ≤ 30 seconds, so your QC team can fix the root cause before the next batch runs.
Not every technology fits every application. Here’s how the most common package leak detection methods compare for food and CPG manufacturers.
| Feature | Bubble Emission (FlexPak) | Vacuum Decay | Pressure Decay | MAP Gas Analysis (Headspace) |
|---|---|---|---|---|
| Shows Leak Location | ✓ Yes — visual | ✕ No | ✕ No | ✕ No — measures gas levels only |
| Test Speed | ≤ 30 seconds | 30–90 sec | 30–120 sec | 3–15 seconds |
| Non-Destructive | ✓ Yes | ✓ Yes | ✓ Yes | ✕ No — needle punctures package |
| Operator Training | Minimal — visual | Moderate | Moderate | Moderate (calibration + gas sampling) |
| Equipment Cost | $3,500 – $15,000 | $15,000 – $60,000 | $10,000 – $40,000 | $2,000 – $10,000 (portable to benchtop) |
| Best For | Food, CPG, QC troubleshooting | Pharma, medical | Rigid containers | Verifying MAP gas mix in food packaging |
| Test Multiple Packages | ✓ Yes | ~ Limited | ✕ No | ✕ No — one at a time |
| Calibration Required | Not required | Regular | Regular | Regular |
| Root Cause Diagnosis | ✓ Immediate | ✕ Requires follow-up | ✕ Requires follow-up | ✕ No — flags bad gas levels, not leak source |
| ASTM Standards | D3078, D6653, D4491, D5094, F2096 | F2338 | Various | ASTM F2391 (headspace gas analysis) |
Need help choosing the right method for your packaging?
Ask about our FPIPA Internal Pressurization attachment for ASTM F2096 testing.
Our team helps food and CPG manufacturers choose the right leak detection setup — no pressure, no jargon.
No complex calibration. No software training. Just fill, place, and test.
Fill the chamber with water, place your sealed package inside, and close the lid. Test multiple packages at once depending on chamber size.
Turn the valve to apply vacuum. The pressure differential forces air out of any defect — creating visible bubbles at the exact leak location.
Bubbles appear right where the defect is. Your team instantly knows if it's a seal, film, or equipment issue — and can correct it before the next batch.
From lid close to leak identification — with no calibration, no software, and no guesswork.
Multiple companies sell bubble emission equipment. Here’s what separates FlexPak from the rest.
Food-grade stainless steel and acrylic throughout. No plastics, brass, or porous components that can harbor bacteria or corrode over time.
Multi-week curing process for maximum durability. Customers running units purchased in 2013 with zero signs of stopping. Lower total cost of ownership.
Real people, real answers — same day. Need to troubleshoot? We'll hop on a call. Need setup help? We'll walk you through step by step.
From small sachets (11" x 8") to large shipping cartons (39" x 22"). Optional add-ons for vacuum-sealed, low-headspace, and internally pressurized packages.
Leak detector works great. No issues and excellent company to deal with.
Leak tester works great and this will save me hours of time every week. Ultimately I’ll be able to turn this over to our hourly workforce. Thanks again for a great product!
We have a tank purchased in 2013 and it's still going with no end in sight, used every day. It’s a solid product and has become an essential part of our quality system.
FlexPak has an outstanding product, pure and simple. It is fast, easy to clean, and very reliable in its feedback. I’m so glad we made this choice; we are able to make small adjustments on the fly to our packaging equipment because of its precise accuracy. 5 Stars for FlexPak!
Whether you’re replacing outdated equipment or evaluating leak detection for the first time — our team will help you find the right fit for your line.
No pressure, no jargon — just honest answers from people who’ve been doing this for over a decade.
