The 9" x 12" EcoLok white deposit bag is the first commercially viable plastic security bag made with 100% degradable film. When EcoLok bags are exposed to sunlight or heat, a two step degradation process is triggered that allows the plastic to break down through oxidation into smaller fragments. The 9" x 12" deposit bag will hold 1,000 notes or 1 bundle. Keep your money safe - and the planet safer
