Abstract: The present invention relates to a foam sheet using cross-linked polylactic acid and method of manufacturing the same, and more particularly a foam sheet using cross-linked polylactic acid and method of manufacturing the same with not only excellent waterproofing and workability but also relatively high foaming ratio and a uniform closed foam cell structure, by producing cross-linked polylactic acid resin in a fixed condition using composites comprising polylactic acid, cross linking agents, and/or co-crosslinking agents, and then forming a sheet shape in a fixed condition using composites comprising the cross-linked polylactic acid and foaming agents, and then foaming at relatively high temperature conditions.

Abstract: Disclosed is a foam sheet using polylactic acid, which provides the advantages of energy reduction and greenhouse gas reduction, and does not emit toxic substances such as toxic gas or endocrine-disrupting chemicals. The foam sheet, according to the present invention, comprises at least one resin layer comprising a biodegradable resin composition including the polylactic acid having an extended chain, a plasticizer, and a foaming agent, and thus provides the advantages of superior processing properties, superior water resistance after processing, energy reduction and greenhouse gas reduction, and of not emitting toxic substances such as toxic gas or endocrine-disrupting chemicals.

Abstract: Disclosed herein is a chip inlaid flooring material using a PLA resin. The chip inlaid flooring material includes a chip inlaid layer, a dimension stabilizing layer, and a base layer, from the top of the flooring material, wherein at least one of the chip inlaid layer and the base layer includes polylactic acid (PLA) resin as a binder.

Abstract: The present invention relates to wallpaper and a method for manufacturing the same. The wallpaper may be manufactured at low energy and low costs regardless of an increase in oil price and does not produce greenhouse gases and hazardous substances in the course of manufacture, use or disposal, or during fire. In addition, the wallpaper can decompose readily in the natural environment, even when buried.

Abstract: Disclosed herein is a board for building or industry comprising biodegradable resin and wooden flour, which is capable of implementing an excellent physical property and protecting the human body and the environment, and a method of manufacturing the same. A method of manufacturing a board may comprise fabricating wooden flour by pulverizing a raw log or wood chips that are raw materials, inputting biodegradable resin to the wooden flour and fabricating compounds by mulling the biodegradable resin and the wooden flour at high temperature, forming the fabricated compounds in a sheet form through mold forming, and cooling the formed board. Accordingly, there are advantages in that an excellent physical property can be implemented, the human body and the environment can be protected because there is no possibility of environmental pollution when the board is buried due to the biodegradable resin, and a cost related to the disposal of wastes can be reduced.
