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 divide into 4 parts: use of Para rubber leaves quantity: 25g, 50, 75 and 100 grams respectively and then put to the test the properties of bioplastics by way of performance test by plastic hardness, elasticity and shape retention of plastic. According to a study of rubber leaves 75 grams, slurry combine together and stickiness. Make plastic adhesion slurry adjacent. Thus are the most appropriate of preparation a bioplastic, but can not be put to the test the efficiency plastics and can not be molded into sheets for use in analyze the characteristics physical properties of plastics by Sealing because plastics offer the softness and combine together insufficient makes sheet When taken folded or seals make tear plastic . No suitable properties in forming a bioplastics. Should lead the way for bioplastics such a trials to improve and study to find methods forming a plastic product that can be deployed by method that actually.
