If the surface plated with silver, in the presence of air with or without the humidity, it will oxidize in due course. Maybe it is better to place it into a vaccum pack avoiding UV light. The silver surface will stay longer. If the silver become oxidizes, you can use a reducing agent to reverse back the reaction.

I have my Baader Solar film for years, and there is no oxidization observed.

The metal film on Baader solar Film is not silver nor aluminium. It don't seems to oxidise over time but it is affected by mould. Two of my very old filters (> 5 years) developed holes caused by moulding.
