When I was small, wallpaper paste was made of flour mixed with water,
worked very well, was a lot cheaper than industrial made paste, and is not
poluted with any chemicals at all, try that.
I have a vague recollection that my step uncle (6 months older than me,
it's complicated) used to make his airfix aeroplanes that way. Can't say
with what success

I think it needs to soak into both surfaces to form a bond - I can't
imagine it working on plastic.

Other disadvantage is tendency to mould - I think modern wallpaper
pastes have mould inhibitors.
