What is shelf life of CAPRUST film stored open to the air?
A. Following are the possible situations, which are to be considered. Example 1 : An exposed sheet of CAPRUST film.:-In this example the sheet’s life span would be directly influenced by its surrounding temperature. Example 2 : An exposed roll of CAPRUST film.:-In this example only the exposed portion of the roll would be directly influenced by its surrounding temperature but not the interior surfaces of the roll. Example 3 : CAPRUST film stored unexposed, i.e. in plain wrappers, cartons, etc. The shelf life of the film in these conditions is essentially unlimited. This is because the film will emit VCI vapors until the interior of the package is saturated, at which time vapor emission will cease. In these conditions the consumption rate of the VCI molecules due to the presence of moisture is reduced to essentially zero. The film will have no need to replace consumed VCI molecules and therefore will cease its emission of VCI molecules. It has thus been proved that when covered in stora
