The purpose of this study was to utilize the biomass resources effectively. In order to apply biomass materials to food packing and agriculture instead of plastic materials,
Ulva pertusa Kjellman was used to produce a biodegradable bio-board in this study. The producing process of a biodegradable board involves refining, defibrating, compression molding and drying. Technical evaluation of produced biodegradable bio-board shows a rupture stress in the range of 15.4 MPa to 73.2 MPa, which is 1.3~6.1 times stronger in comparison with the polystyreneplasticmaterialpresentlyusedinfoodpackingcontainer,andtheshrinkageofbio-boardsincreasedwith the decreaseofthemoisturecontent. Therefore, the useof bio-board asa substitute for oil-based plasticmaterialsin foodpackingcontainer,culturepansandmulchfilmistechnicallypossible.
