Sanna Laukkanen

Sanna Laukkanen works at Measurlabs as an organic materials testing expert, focusing mainly on fibers and textiles. Sanna majored in fiber and polymer engineering at Aalto University and holds an MSc (tech.) in chemical engineering. She wrote her master’s thesis on additives used to optimize kraft-lignin pelletizing and pellet performance.

Sanna’s studies and previous work experience have been centered around the analysis of synthetic and natural polymers. She has worked with R&D of lignin-based resins, analyzed oil and biorefinery products, and studied food safety standards and legislation related to the production of packaging materials. Sanna is especially interested in the development of sustainable packaging solutions and lignin-based innovations.

Water vapor transmission rate (WVTR) of plastic films and sheeting

ASTM F1249, ISO 15106-2
Determination of the water vapor transmission rate (WVTR) according to the ASTM F1249 standard. WVTR describes the amount of water vapor that passes through a material over a set period. It is an important quality indicator in food and cosmetics packaging, as an effective moisture barrier is critical to keeping products fresh and preventing spoilage. In this WVTR test, two samples per material are measured simultaneously to ensure the reliability of the measurement. The results are expressed as g/m2/day. Please disclose the desired temperature (from 18 to 40°C) and the desired relative humidity (from 20% to 100%) when placing the order. This measurement is applicable for plastic films and sheeting materials with WVTR values between 0.005 and 2400 g/m2/day. If you wish to test finished packaging instead, check out the WVTR measurement for packages.

Oxygen transmission rate (OTR) of plastic films and sheeting

ASTM D3985, ASTM F1927, ASTM F2622-08, …
Determination of the oxygen transmission rate of plastic films and sheet-like materials. The test is performed on two parallel samples simultaneously. Measurement conditions (temperature and relative humidity) can be chosen according to the intended use of the material. Oxygen permeability 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 10 °C to 38 °C) and relative humidity (either 0% or from 20% to 90%) upon ordering. This measurement is suitable for plastic films with OTR values between 0.05 to 20 000 cm3/(m2 * day).

Oxygen transmission rate (OTR) of packages

ASTM F1307
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.

Water vapor transmission rate (WVTR) of packages

This test is designed to measure the water vapor transmission rate (WVTR) of packages, such as cups, bottles, trays, and containers. The analysis includes three replica measurements. This test is not suitable for films or sheet-like materials. Please see the water vapor transmission rate (WVTR) of films and sheeting instead. Upon ordering, please specify the sample dimensions and desired testing conditions. The chosen temperature can be between 15 and 55°C and the relative humidity between 20 and 100% RH.
