A snack bag that lets in a fraction more oxygen than spec, a bottle cap that under-torques, or a laminate that migrates a compound above the allowed limit — none of these show up on a visual inspection. They show up later, as a customer complaint, a failed audit, or a regulatory rejection. Testing the packaging before the product goes in is what keeps that from happening.
Excess oxygen or moisture ingress leads to oxidized fats, stale snacks, and spoiled dairy or meat products before the printed date.
Migration of ink solvents, plasticizers or monomers into food can breach FDA, EU or GB food-contact regulations and trigger a recall.
Incorrect gas fill or a weak seal on a modified-atmosphere tray shortens shelf life and increases the risk of microbial growth.
These parameters cover the majority of specification requirements across flexible pouches, rigid trays, bottles and cartons used in food and beverage packaging.
| Property | Why it's tested | Reference standards | Recommended instrument |
|---|---|---|---|
| Water Vapor Transmission Rate (WVTR) | Predicts moisture pickup or loss for snacks, powders, baked goods and dried foods | ASTM F1249 / E96, ISO 15106 | Water Vapor Permeability Analyzer |
| Oxygen Transmission Rate (OTR) | Determines oxidation risk for fatty snacks, coffee, dairy, meat and beer/wine packaging | ASTM D3985, ISO 13274 | Oxygen Permeability Analyzer |
| Headspace O₂ / CO₂ Analysis | Verifies gas fill accuracy in MAP trays, bottles and cans, and detects seal or barrier failures | Internal method / ASTM F2013 practice | Headspace & Gas Analysis |
| Overall & Specific Migration | Confirms packaging materials don't transfer substances into food above regulatory limits | EU 10/2011, FDA 21 CFR 175-178, GB 31604 | Migration Tester |
| Residual Solvent & Odor | Screens printed and laminated packaging for solvent taint before it contacts food | Internal GC method, ASTM E679 | Gas Chromatography |
| Heat-Seal Strength | Confirms pouch, tray and lidding-film seals hold under the actual sealing window used on-line | ASTM F2029 / F88, ISO 11607-2 | Laboratory Heat Sealer + Tensile Tester |
| Package Leakage / Seal Integrity | Detects pinholes and weak seals on finished pouches, trays and bottles before shipment | GB/T 15171, ASTM D3078 | Leakage Tester |
| Bottle & Container Integrity | Verifies wall thickness distribution, internal pressure and load resistance of glass and rigid bottles | ASTM C147, ISO 8113 | Glass Container Test Equipment |
The core test set stays similar across categories — what changes is which format and which standard a customer specification or regulator expects.
Flow-wrap film and stand-up pouches — WVTR and OTR drive crispness and rancidity shelf-life claims.
Cup lidding film, cartons and pouches — seal strength and barrier protect freshness through cold chain.
Modified atmosphere trays and vacuum pouches — headspace gas analysis and seal integrity are critical.
PET/glass bottles, cartons and spouted pouches — container integrity, cap torque and gas barrier matter most.
A typical food/beverage QC lab builds around a barrier tester, a migration/GC setup and a seal or container integrity tester. Together they cover most specification and audit needs.
