Eco Film
This thick plastic film has the magical property of disappearing almost instantly when it gets wet. It comes as a 900mm wide flexible (almost) clear film 75 microns thick and is sold by the metre.
The material is supplied with an information leaflet that explains more about the film and its potential uses both in industry and in the context of designing and making. Uses in project work include simple water–activated alarms (e.g., contacts close or clockwork starts running when the film dissolves); water activated containment devices (e.g., a spring–loaded structure opens or the contents of a glued bag are exposed under water); graphic products such as bags and posters that bio–degrade at an accelerated rate.
