But my colleagues and I have Current guidelines suggest that film stored in the same conditions could last about 450 years. For films made in 1950, when acetate films were becoming popular, this implies that vinegar syndrome won’t develop until about the year 2400.But our research predicts that films stored in recommended conditions may last as little as 70 years before developing vinegar syndrome.

More properly referred to as acetate film base degradation, vinegar syndrome is a very similar problem to nitrate base deterioration.
According to our model, a film produced in 1950 and stored in the recommended conditions since then could develop vinegar syndrome this year.To understand how film might degrade over long periods of time, scientists perform experiments on film at high temperatures and relative humidity. The symptoms of vinegar syndrome are a pungent vinegar smell (hence the name), followed eventually by shrinkage, embrittlement, and buckling of the gelatin emulsion. Researchers at Queen Mary University of London were recently able to recover images from an afflicted film reel, which was too brittle and fused together to be unwound, using an X-ray Archives use guidelines to plan their film preservation strategy. This is why archives store their film collections in a cold and dry environment. Prmdeal.com for you to collect all the coupons on the Vinegar Syndrome website! About Vinegar Syndrome.
