Analysis of different biodegradable materials and its technique to produce dishware

The concept of Green packaging material and biodegradable material is introduced in this paper. Biodegraded material is a kind of Green material, which is easily reclaimed and reused, it does not pollute the environment, and it can decompose quickly, there is not insurant to produce after trash. The main material starch and plant fibre for produce the dishware is analyzed in this paper. By cooperating with Shandong Jiufa Group Company, we have done lots of test, the raw and processed materials are corn starch and pure plant fibre (bamboo powder, or bagasse), and the additives are edible and degradable. The high effect and clean production comes true after cosmically production, and the energy sources and resources can be reduced greatly. There are two or three times to press the mould producing dishware using starch material for the mixture materials contain lots of water, so the steam of mixture materials must to be vaporized. The plant fibre dishware producing technology is more advanced than that of starch dishware as only one time is needed for fibre material dishware shaping. Based on lots of tests, key technique for producing the dishware is studied, the mould structure for fibre production optimized. The LCA analysis of starch and plant fibre material have been done and the test of degradable effect have been made, the test results shows that this packaging material can finally be separated to carbon and water after disused by the action of animalcule and water and air.
