ISO 15106-1 — Determination of water vapour transmission of plastic films
ISO 15106-1 specifies an instrumental method to determine the water vapour transmission rate, WVTR, of plastic films, sheetings and multilayer assemblies. The method uses a humidity sensor to measure moisture transfer through a specimen, enabling fast, reproducible results across a wide measurement range.
Overview
The standard defines the purpose, measurement principle, test conditions and evaluation procedures, so results are comparable and reproducible.
Purpose and scope
ISO 15106-1 is intended to measure water vapour transmission for single plastic films, coatings and multilayer laminates. Typical uses are quality control, material selection and verification of barrier performance for packaging and technical applications.
Measurement principle
The humidity sensor method separates a dry chamber from a humid chamber with the test specimen in between. Water vapour diffuses through the specimen, the resulting humidity change in the dry chamber is recorded by a sensor, and the WVTR is calculated from that change. The method supports rapid testing and covers a broad WVTR range.
Application areas
Medical and pharmaceutical packaging
Sterile packaging, blisters and medical pouches need controlled moisture barriers to protect products. The standard helps validate materials and demonstrate compliance with product specifications.
Technical films and barrier layers
In electronics, construction membranes and technical multilayer systems, moisture permeability can affect performance and durability. ISO 15106-1 provides comparable WVTR data for material development and quality control.
Food packaging, films and laminates
Food packaging materials require low WVTR to protect aroma, texture and shelf life. ISO 15106-1 is used to evaluate and compare films and laminates for their moisture barrier performance.
