The science project bioplastics from cellulose is in Para rubber leaves. This experiment were to study and determine the quantity of cellulose suitable in the production of bioplastics from Para rubber leaves and test the properties of bioplastics from Para rubber leaves. The experiment study into 4 parts: use of Para rubber leaves quantity 25g, 50g, 75g and 100g. The result showed that Para rubber leaves in the amount 75g solution have toughness and plastic is not easy to break when efficiency test found bioplastics have strength and elasticity and then the molded into the plastic sheet but from the experiment can't forming by the sealer because plastic is limpness but it is qualified in forming a plastic therefore; we should find methods to that can the formability is really plastic.
