Yes, but it should not be treated as a perfect prediction of real-time shelf life.
Accelerated aging can help identify risks such as:
- embrittlement;
- blocking;
- odor development;
- seal degradation;
- color change;
- loss of elongation;
- adhesive failure.
However, natural-fiber and compostable-polymer systems can respond to heat and humidity in complex ways. The test conditions need to be relevant, and accelerated results should be supported by real-time storage samples.
I would run both:
- accelerated conditioning for early risk detection;
- retained commercial samples under normal storage for ongoing confirmation.
Shelf-life claims should be based on evidence, not copied from the resin supplier.
