Re: [ARSCLIST] Acetate disc sleeves

Eric:

As Richard pointed out, today films are being stored in ventilated cans for
a variety of reasons with the main rationale to help prevent vinegar
syndrome.  Ventilated cans permit the dissipation of acidic decomposition
by-products from the film can which in turn encourages the diffusion of the
by-products from the film pack.  This is important because the acidic
by-products are a catalyst for the decomposition reaction and thus
accelerate the reaction.  ProVent and ProVent Audio containers are
ventilated to allow the film and audio tape to "breathe".  Hope this helps.

Eric,

I am sure there is room for debate, but films are being stored in
ventilated cans these days for a variety of reasons.

You might browse

I think Hollywood Vaults and the National Film Board of Canada are
using this product -- at least for some of the storage.

You might ask over on the AMIA list for this.

Cheers,

Richard
