2) Do any ink suppliers provide ink in cans with plastic liners, & perhaps
resealable liners, e.g., zip-lock type bag? This could prevent direct contact
of the ink with the can and make return of the empty can to the supplier or
perhaps for recycle as scrap metal, more feasible. Also, would a resealable
bag reduce skinning of the residual ink or ink that is saved, along with
spraying with an anti-oxidant?
