    • The present invention relates to biodegradable plastic composition comprising rice powder and/or corn powder, which can be characterized in comprising 100 parts by weight of polyolefin matrix resin; 5 to 400 parts by weight of grain powder selected from the group consisting of rice powder, corn powder and mixture thereof. The biodegradable plastic composition according to the present invention can be manufactured in various forms such as injection molding product, sheet molding and blow molding product, which have excellent physical properties and product stability. The efficiency of waste disposale of the product manufactured with the composition can be remarkably improved since the rive powder or the corn powder contained in the composition can be degraded by microbes in the nature after a certain period. Therefore, the problems of soil, air, and sea pollution caused by burial or incineration of the wastes of conventional plastic molding product can be minimized.
    • 本发明涉及包含米粉和/或玉米粉的生物可降解塑料组合物,其特征在于包含100重量份的聚烯烃基质树脂; 5〜400重量份选自米粉,玉米粉及其混合物的颗粒粉末。 根据本发明的生物降解性塑料组合物可以以各种形式制造,例如具有优异的物理性能和产品稳定性的注塑产品,片状模塑和吹塑产品。 使用该组合物制造的产品的废弃处置效率可以显着提高,因为组合物中所含的裂纹粉末或玉米粉末在一段时间后可能会被微生物降解。 因此,传统塑料成型产品的废弃物的埋藏或焚烧引起的土壤,空气和海洋污染问题可以最小化。
