The films are delivered in an envelope and are packaged in a plastic bag. A sticker indicating the printable side, is attached to this. They are both printable and writable (though going from the coating, if you want to remove the pin wet). Grpßen a disadvantage they did: by the heat of OHP they begin to curl in. In particular, the edges bend upwards, which of course affects the quality of the presentation of the film on the wall.
