Newspaper, A4 paper, office paper, and cardboard boxes (shoe and supermarket boxes) will decompose and release acidic vapors over the years? If I store an electronic device inside such a box with these papers, will it release acidic vapors and corrode the electronic boards and metal connections of the device? If the cardboard box and these papers come into physical contact with any electronic part of the device, will they corrode it because they contain acid in their composition?
