keeping the pva ALWAYS in a closed box with moisture absorbent, also when printing, really helps. I uise a simple cheap box with a printed spool holder;

There are also commercial boxes available but they really don't do more than any plastic container;

Yep
This is moisture. There is only so much you can do.
When you print is the spool covered or fitted to the back?
Basically you know boiling water creates steam, well as we print twice as hot compared to boiling point the transition is very fast. This can lead to the now gas form of the water to get trapped if the amount is very small. When the amount of moisture is above a certain amount the amount of gas expand where it bursts out of the plastic and that’s the pop.
There are printable solutions that encase the PVA whilst printing and contains moisture absorption (latter isn’t printable) I have designed one and is on youmagine and thingiverse. It’s bright orange.
I have designed something better but haven’t tested it yet. But will be available once I have.
