FB and CFB for freezing

My Dad used to do a pickled french beans that were yum - must pinch his recipe he hasn't done them for a while. I find it is how you freeze french beans rather than which ones. I use to blanch them, bag them, wrap with kitchen roll, then bag again - faffy but it made a difference and I told this to someone else and they had struggled but this worked for them.

Veggie do you eat beans anymore or are they still too squeaky???

NG, wrap up the plastic bag full of blanched beans in kitchen roll, then bag again?? Sounds strange. Any idea why it works?
