Thank you for the question. For a document that has been covered on both sides with sticky film, I would consult with a professional conservator. There are many variables at play that could affect the longevity of the piece including the make-up and condition of the paper when it was covered, the type of adhesive that was used and how that will react over time, and the type of plastic film that was used. If conservation isn't an option right now, the best thing to do would be to keep it in as stable an environment as possible since temperature and humidity changes could cause any of the elements listed above to begin changing and deteriorating.
