Basics
- PET (Plastic) undergoes hydrolysis when even slightly damp at it's melting point
- THUS it is best to store it at least moderately dry, and/or dry pre-use (in some process/machine integrated dryer)
To Do
- Specific data on water level vs degradation (a graph of water g/kg vs tensile strength or something?)
- Find Methods of in-machine drying (fluidized in hot air, like a hot air corn popper?)
