Polyvinyl alcohol is compatible with a wide range of chemicals and solvents. However, some chemicals may react with the PVA molecular structure during extended periods of storage, adversely effecting solubility and causing the film to discolor and/or become brittle. These changes reduce shelf life and can be accelerated by high temperature and humidity.
Accelerated testing is vital to check your products affect on film properties. Aicello can provide accelerated testing to assess the changes in the film in contact with your product for a fee, which provides a foundation for your further testing in the final package and shipping configuration. We can also assist in the design of your in-house testing procedures.
