In response to your questions:
1. Using plastic wrap might be possible, but from my experience, we're often
taliking of different functions. We use laminated kraft as a laydown sheet on
top of the pallet just before loading printed matter on the pallet. We use
stretch wrap (not shrink wrap) to secure the load prior to shipment. We use
shrink wrap for internal packaging.
2. This is an interesting idea, one that we explored with several ink
suppliers. I believe the problem comes in handling the ink, especially
lithographic inks which must be scooped out of the cans. Tearing of the liner,
or just keeping it in place (along the can's sides) would likely be difficult.
We crush our empty (RCRA empty) cans and recycle them with a metal recycler.
Crushed containers obviously can no longer "contain", and so we believe we
reduce our exposure to liability this way (even though we have on file TCLP
tests that verify out inks are non-hazardous.
Hope this helps.

I have a couple of questions related to offset printing:
1)From a recyclability viewpoint, would it be more feasible to use plastic
wrap instead of coated vapor barrier paper on paper shipments? Would shrink
wrapping be more expensive?
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?
