Strange that this question comes up now!
Have just come back from Manitoba (yesterday) - and whilst watching extraction taking place (whilst
the others waded through the crop!) - I asked if freshly drawn comb on plastic foundation often
ripped off during uncapping (Cowen Jumbo being used).
The answer was given as follows:
White plastic foundation "peels".
Black plastic foundation (from China) did/does not.
This was then demonstrated.
The thoughts are, that due to the molded cell walls on the black foundation being deeper - better
adherence resulted.
I cannot given any more evidence than this - but it appeared at the time to be correct!
Regards,
Peter
