It's well know that pthalates (softeners adds flexibility to plastics)
reacts badly with styrene.
Pthalates laced plastics also interact badly, namely famicoms. The soft cords would need to
be protected from contact with the hard main console. The laced wires soften and damage the hard plastic (melting appearance)
Systems that suffer from this are NES, etc. Systems packed in styrene.
I propose standards for preserving systems from damage.
Thin acid free paper bags (but soak through may happen). Layering may solve this.
Inert plastic bags unaffected by styrene or pthalates (research needed).
Cloth bags, like cotton cheesecloth.
* One could have baggies made with drawstrings.
Systems, controllers and other parts could be placed inside, yet be free enough to fit into the
original spots in the styrene. Long, double ended bags could be tied around the controllers and
the wires on the famicom where they emerge from the system.
Inert, acid free brown paper slips could be used to preserve sealed manuals.
