TRANSPARENT FLEXIBLE HEAT SEALABLE FILMS-EVALUATION OF ABILITY TO PROTECT AGAINST CORROSION

摘要

Ten different transparent plastic films were evaluated for their ability to provide protection against corrosion to steel panels with and without preservation in an accelerated humidity environment. The films represented water vapor transmission rate (WVTR) values currently required by military specifications.nResults showed that films with low WVTR values did not prevent the entrance of water vapor, which resulted in corrosion. Prevention against corrosion was maintained for extended periods of time only when preservatives were used.
