Oxygen transmission rate (OTR) of plastic films and sheeting

Determination of the oxygen transmission rate of paper and cardboard materials. The test is performed on three identical samples to ensure repeatability. Measurement conditions (temperature and relative humidity) can be chosen according to the intended use of the material. The oxygen transmission rate is typically measured at 23 °C and 0% relative humidity as per standard ASTM D3985. In moist conditions, for example at 38 °C and 90% relative humidity, standard ASTM F1927 is used. Please disclose the desired temperature (from 15 °C to 50 °C) and relative humidity (either 0% or 10% to 90%) upon ordering. This measurement is suitable for paper and board materials with OTR values between 0.01 to 5000 cm3/(m2 * day).

This test is designed to measure the oxygen transmission rate of finished packages, including cups, bottles, trays, and containers. Two replica measurements are included in the displayed price. Temperature can be adjusted from 15 to 55 °C, and relative humidity can be either 0% or between 5 and 90% RH. This test is not suitable for films. Please see the oxygen transmission rate (OTR) of films and sheeting if you need testing for film samples. Please specify the sample dimensions and testing conditions upon ordering.

Phthalates are a group of chemicals widely used as plasticizers, which make plastics more flexible and durable. They have also been used as additives in products such as cosmetics and personal care items. Several phthalates have been identified as endocrine-disrupting agents or as chemicals toxic to reproduction. Exposure to phthalates can occur through: Oral exposure Food: Exposure occurs via migration from food packaging., Children's toys: Children often put toys in their mouths.., Inhalation: Breathing in dust from vinyl flooring or fragrances (like perfumes) can cause exposure to phthalates via inhalation., Skin contact: Phthalates present in cosmetics, lotions, and soaps can be absorbed through the skin.. For other listed matrices apart from cosmetics, the analysis package covers the following substances included in the REACH Authorization List: Substance Abbreviation CAS number Diisobutyl phthalate DIBP 84-69-5 Dibutyl phthalate DBP 84-74-2 Benzyl butyl phthalate BBP 85-68-7 Bis(2-ethylhexyl) phthalate DEHP 117-81-7 Di(n-octyl) phthalate DNOP 117-84-0 Diisononyl phthalate DINP 68515-48-0 Diisodecyl phthalate DIDP 26761-40-0 Products that contain restricted phthalates in concentrations higher than 0.1% may be removed from the market. The analysis package for cosmetic products contains the following phthalates: Substance Abbreviation CAS number Bis(2-ethylhexyl) phthalate DEHP 117-81-7 Benzyl butyl phthalate BBP 85-68-7 Dibutyl phthalate DBP 84-74-2 Diisononyl phthalate DINP 68515-48-0 Di(n-octyl) phthalate DNOP 117-84-0 Diisodecyl phthalate DIDP 26761-40-0 All the above-mentioned substances are prohibited in cosmetic products (Annex II of Regulation (EC) No 1223/2009).

Analysis for quantifying dioxins and furans (PCDD/F) in various packaging materials (e.g. food and cosmetics packaging) and their raw materials, including plastics, paper, and rubber. Dioxins and furans are a family of chlorine-containing chemicals considered bioaccumulating, persistent organic pollutants (POPs) that can be toxic even at low doses. While regulatory limits apply mainly to food and feed, packaging materials can be a source of indirect exposure to dioxins and furans. Recycled materials tend to pose relatively high risks, depending on the quality of the raw material and the effectiveness of the decontamination process. The following substances are included in the analysis: Dibenzo-p-dioxins (PCDDs) Polychlorinated dibenzofurans (PCDFs) 2,3,7,8-TCDD. 2,3,7,8-TCDF. 1,2,3,7,8-PeCDD. 1,2,3,7,8-PeCDF. 1,2,3,4,7,8-HxCDD. 2,3,4,7,8-PeCDF. 1,2,3,6,7,8-HxCDD. 1,2,3,4,7,8-HxCDF. 1,2,3,7,8,9-HxCDD. 1,2,3,6,7,8-HxCDF. 1,2,3,4,6,7,8-HpCDD. 1,2,3,7,8,9-HxCDF. OCDD. 2,3,4,6,7,8-HxCDF. 1,2,3,4,6,7,8-HpCDF. 1,2,3,4,7,8,9-HpCDF. OCDF. Testing is often performed for the following reasons: Analyzing recycled PE, PP, and LDPE intended for cosmetics packaging according to CosPaTox guidelines., Analyzing paper and board bleached with elementary chlorine according to the requirements of TemaNord 2008:515 guidelines..

The EU Packaging and Packaging Waste Regulation (PPWR) limits heavy metal content in all packaging and PFAS content in food packaging. This analysis package includes the following analyses to demonstrate compliance: Total fluorine (TF), Heavy metals (Pb, Cd, Hg, and Cr), Further total organic fluorine (TOF) and targeted PFAS analyses where required/requested.. The displayed typical price applies to TF analysis and heavy metal determination, which are sufficient for most materials. According to a recently published Commission guidance document, further PFAS testing is not required if TF content is less than 50 ppm. If the 50 ppm limit is exceeded, the Commission recommends the following steps: TOF analysis with py-GC/MS to determine whether the fluorine is organic (potentially PFAS) or inorganic (e.g., fluorine impurities in talc and other mineral fillers). If TOF content is less than 50 ppm, no further testing is needed., If the TF and TOF analyses are not sufficient to show that PFAS are not present, a direct TOP assay (total oxidizable precursors) should be used to check compliance with the limits set for individual PFAS compounds and the sum of PFAS.. Both of these analyses are also available at Measurlabs. Please describe the composition of the packaging material when requesting an offer (materials with metal components may require the testing procedure to be modified). Please also let us know how many materials you need tested, as we are happy to offer discounted pricing for large batches.

Determination of the total organic fluorine (TOF) content in combustible materials using combustion ion chromatography (CIC). By default, TOF is analyzed as total fluorine (TF). If required, total inorganic fluorine (TIF) can be measured as well, and TOF calculated as the difference between TF and TIF. TOF analysis gives information about the total amount of organic fluorinated compounds. It can also be used to evaluate the presence of per- and polyfluoroalkyl substances (PFAS) in the material, even though individual PFAS compounds can't be analyzed with this method. The analysis is suitable for many different materials. Please describe the sample in detail when requesting an offer to help us prepare a quote quickly.

Determination of the water vapor transmission rate (WVTR) of ultra-high barrier materials. The method can also be used to test moderate barrier materials under high-temperature conditions. Please disclose the desired temperature (from 10 °C to 85 °C) and the desired relative humidity (from 60% to 100%) when placing the order. This measurement is applicable for films and sheeting materials with WVTR values between 1x10-6 and 10 g/m2/day. If you wish to test finished packaging instead, check out the WVTR measurement for packages. The price of the test consists of a flat rate cost per sample plus one day of measurement time. Please contact our experts for an offer.
