bearspread, as I understand from reading the SealaFresh information given here, it seems to not yet be a company, but only a new technology being developed for preserving the shelf-life (or, container life) of perishable agricultural commodities. My guess is that its inventor has not yet formed a corporation or webpage, etc., and that may be the reason we don't find it through Googling the name, SealaFresh? It sounds like DoubleCrown may be combining that technology with their own patented designs somehow, but we should wait for more reporting on this subject.
If anyone has more info on this, we would like to have you comment on it? However, just because there is no available website or Google info on SealaFresh, doesn't mean it isn't a real new technology still being worked out.
