Results 'Presently it is not possibleto use largeamounts of biodegradable plasticsfor packaging. From technological and economical viewpoint comparison of degradable plastics and convention- al standard material shows definite advantage for the latter.The machinability of biode rad able plastics and their material usage properties and properties needed in order to fulfil?thei; protective function have to be improved considerably. This is the case in particular when they are envisioned for use in the food area. However, with the help of modern surface technology thin coatings can be applied which can improve the barrier properties of these materials. For certain packagin applications Biopol and starch based products arealready on t
