Smithers can support with testing to ASTM D918. This standard determines the blocking resistance of flexible types of packaging materials, including the following:
The test method provides a range of standard conditions of temperature and relative humidity at constant pressure for a specified time which is designed to simulate varying climatic conditions that may be encountered in the manufacture, storage, transportation, or use of the materials. A simple subjective three-level assessment is made: no block, some block or well blocked.
