As Lachlan says - the notice isn't about manufacture, it is about packaging.By combining production lines, that means they're shutting done one or more lines. Not good possibly. On the other hand, that might make the production more efficient lowering costs and keeping the product profitable so they won't shut down production entirely. Of course, they already stated that Velvia 50 in sheet film is going to end soon. That's no good because I really like that film and just started to shoot 4x5.
Of course, confectioning (including packaging) and distribution costs as much or more than manufacturing, so perhaps "production" might be the right word.
