I'm going to guess as a packing. The only other use of white lead that
I've heard of is for filling the weave on the canvas of a canoe before
painting.

Many years ago I used white lead in the restoration of the roof of a
wooden railway car. We used the traditional method of stretching
canvas over the wooden roof, soaking it with a paste of white lead and
linseed oil,and nailing it before it shrank.With occasional painting,
it lasted outdoors for over 20 years.

And for heaven's sake, please make sure no one eats it! ;-)

I thought that was the whole idea of the lead. Wouldn't it offer
protection against mould, fungus and various tiny critters that want
to eat the canvas? I've often wondered if that was not also an
advantage of lead in paints.
