OptiTape is an optically clear, double sided mounting film, for use with no-adhesive One Way Vision films, such as BannerVue and RetailVue, when applied to transparent surfaces such as windows, doors and acrylics. It is recommended to interior mount no-adhesive perforated vinyls, to minimise contaminates from adhering to the mounting film in the perforations, thereby maintaining the One Way Vision effect.
