Oxygen and Gas Barrier Testing in Our High Barrier Film Testing Service

Oxygen transmission rate per ASTM D3985 and ISO 15105-2 — a coulometric sensor measures the steady-state oxygen flux through the high barrier film at controlled temperature and humidity, providing the OTR in cc/m²·day·atm essential for shelf-life prediction of oxygen-sensitive products.
Oxygen transmission rate at multiple humidity levels per ASTM F1927 — the film is tested under a range of relative humidity conditions to characterize the humidity-dependent barrier performance that is critical for EVOH and nylon-based barrier films.
Carbon dioxide and nitrogen transmission rate per ASTM F2476 and internal manometric methods — for modified atmosphere packaging films, the permeability to CO2 and N2 is determined to predict package headspace evolution and internal pressure changes during distribution.
Total gas permeation by manometric and isostatic methods per ASTM D1434 — the complete gas transmission profile is measured for air, oxygen, nitrogen, and specialty gases to support material selection and process design.
Aroma and solvent vapor transmission by gravimetric permeation cells — the film's barrier to flavor compounds, organic solvents, and volatile migrants is quantified to ensure product quality and regulatory compliance for printing ink and adhesive components.

Water Vapor and Moisture Barrier Testing for High Barrier Films

Water vapor transmission rate per ASTM F1249 and ISO 15106-2 — a modulated infrared or electrolytic sensor measures the moisture vapor passing through the high barrier film under steady-state conditions, providing the WVTR in g/m²·day that directly correlates with product shelf-life and package integrity.
Water vapor transmission rate by gravimetric cup method per ASTM E96 and ISO 2528 — the traditional desiccant or water cup method is used for referee testing and for films where the sensor methods are not applicable due to high transmission rates or surface roughness.
Moisture vapor transmission at tropical and cold chain conditions — WVTR is measured at 38°C and 90% RH, and at refrigerated and frozen temperatures, to simulate the real distribution environments for the high barrier film product.
Water absorption and liquid water resistance per ASTM D570 and ISO 62 — the mass change of the film after immersion in water is measured to verify that the barrier layer does not absorb moisture that would plasticize the polymer and reduce its barrier function.

Mechanical and Physical Property Testing of High Barrier Films

Tensile strength, elongation at break, and modulus per ISO 527-3 and ASTM D882 — the force, stretch, and stiffness of the high barrier film are measured in machine and transverse directions to ensure the film can withstand printing, laminating, and packaging machine stresses without yielding or delamination.
Tear resistance by Elmendorf method per ISO 6383-2 and ASTM D1922 — the force required to propagate a tear from a controlled slit is quantified, verifying the film's resistance to puncturing and catastrophic splitting during handling and transport.
Dart drop impact resistance per ASTM D1709 and ISO 7765-1 — a weighted dart strikes the film to measure the energy required to cause failure, simulating the impact of product corners and sudden shock loads on the packaged film.
Puncture and probe resistance per ASTM D5748 and EN 14477 — a probe is driven through the film at a controlled rate to determine the puncture force and elongation, critical for films used in sharp-edged product wrapping and vacuum pouches.
Heat seal strength and hot tack per ASTM F88 and ASTM F1921 — the force required to peel a heat seal and the strength of the seal while still hot are measured to validate the sealing performance of the high barrier film on high-speed form-fill-seal machines.
Coefficient of friction per ISO 8295 and ASTM D1894 — the static and dynamic friction are measured to control film slip behaviour on automatic filling lines and to prevent blocking or mis-feeds.

Thermal and Dimensional Stability Testing of High Barrier Films

Differential scanning calorimetry for melting point and glass transition per ISO 11357-2 and ASTM D3418 — the thermal transitions of each layer in the high barrier film are identified to define the heat seal window, retort processing limits, and the maximum service temperature.
Thermogravimetric analysis for composition and volatile content per ASTM E1131 — the mass loss profile quantifies the organic and inorganic content of the film, including residual solvents, moisture, and filler levels that affect barrier performance and printing.
Dimensional stability under heat per ASTM D1204 and ISO 11501 — the percentage shrinkage of the film after exposure to a defined elevated temperature is measured to verify that the high barrier film remains dimensionally stable during heat sealing, retort, and hot fill processes.
Low-temperature flexibility and brittleness per ASTM D1790 and ISO 8570 — the film is conditioned at sub-zero temperatures and tested for cracking to ensure it maintains integrity during frozen food packaging and cold chain distribution.

Optical and Surface Quality Inspection for High Barrier Films

Haze and total luminous transmittance per ASTM D1003 and ISO 14782 — the percentage of scattered light and the total transmitted light are measured to ensure clarity and visual appeal for retail packaging where the product must be visible.
Gloss at specified angles per ASTM D2457 and ISO 2813 — specular reflectance is measured to quantify surface shine and to match the aesthetic requirements of the brand or end-use.
Surface energy and wetting tension per ASTM D2578 and ISO 8296 — dyne pen or contact angle measurement confirms that corona, flame, or plasma treatment has achieved the required surface energy for ink adhesion and lamination bonding.
Metallization uniformity and pinhole detection — optical microscopy and light table inspection quantify the density and size of any pinholes in the vacuum-deposited aluminum or AlOx/SiOx coating that would create localized barrier defects.
Metal adhesion and coating integrity per ASTM D3359 and internal peel protocols — tape testing evaluates the adhesion of the metallization or oxide coating to the base polymer film to prevent barrier layer detachment during flexing and processing.

Chemical Safety and Regulatory Compliance Testing for High Barrier Films

RoHS compliance per IEC 62321 and EU Directive 2011/65/EU — quantitative screening for lead, mercury, cadmium, hexavalent chromium, PBBs, and PBDEs in the film, adhesives, and printed layers to meet substance restrictions for electronic product and consumer packaging.
REACH Annex XVII and SVHC screening — targeted analysis of Substances of Very High Concern including specific phthalate plasticizers, organotin stabilizers, and short-chain chlorinated paraffins present in the high barrier film formulation.
Phthalates and plasticizers per CPSC-CH-C1001-09.4 and EN 14372 — GC-MS determination of the six restricted phthalates in flexible and printed films intended for children's products or food contact applications.
Overall migration and specific migration for food contact per EU Regulation 10/2011 and FDA 21 CFR — the high barrier film is exposed to food simulants under the most severe time and temperature conditions representative of the intended use, and the total extractable mass and specific levels of restricted monomers, plasticizers, and heavy metals are quantified.
Polycyclic aromatic hydrocarbons per AfPS GS 2019:01 PAK — for carbon-black-coloured or recycled-content barrier films, the 15 restricted PAHs are extracted and quantified to confirm compliance with European product safety limits.
Halogen content by combustion ion chromatography per EN 14582 — total fluorine, chlorine, bromine, and iodine content is measured to support halogen-free declarations and to verify PVDC content for recycling stream compatibility.
Residual solvents and volatile organic compound emissions per ISO 16000-3 and VDA 277 — headspace GC-MS identifies and quantifies residual printing solvents, laminating adhesives, and retained monomers that could migrate into packaged products or contribute to indoor air pollution.
