The biodegradation Characteristic foaming body and its production manner for sheet, and the biodegradation Characteristic formation item and its production manner which use the particular foaming body

摘要

Topic It is superior in biodegradation Characteristic, compactibility, and heat resistance furthermore when it utilizes in the packing container and the like of the food even, offer the biodegradation Characteristic foaming body and its production manner, and use the particular foaming body the biodegradation Characteristic formation item and its production manner whose security is high. Solutions The vegetable fiber, the starch, and the biodegradation Characteristic thermoplastics are mixed, expansion ratio is within 15 times and is the biodegradation Characteristic foaming body which foams. It is desirable, the vegetable fiber 5 - 40 weight %, the starch 5 - 30 weight % features that it contains. In addition, the biodegradation Characteristic thermoplastics, being something which mixes the resinous principle of 2 types or more where melting point differs are desirable, especially, it is more desirable for the resin of melting point extensibility to be larger than the resin of high melting point low. Choice figure It is not
