The invention discloses an alkali-resisting silver foil for tableware decoration. The alkali-resisting silver foil is composed of raw materials of, by weight, 50-60 parts of silver powder, 120-140 parts of aluminum powder, 10-15 parts of cobalt powder, 8-12 parts of silica powder, 5-10 parts of nanometer silicon carbide and 2-5 parts of manganese oxide. The alkali-resisting silver foil for tableware decoration is made of a non pure silver metal alloy material, therefore, the price is lower compared with pure silver foil; the alkali-resisting silver foil is relatively stable in gloss and is nottoo dazzling under high light and is not too gloomy in a dark place; the alkali-resisting silver foil is good in toughness and is resistant to processing; and the alkali-resisting silver foil has good alkali resistance, the appearance of the silver foil does not affected by washing with an alkaline cleaning agent for a long time, and the decorative effect of the silver foil is not affected. 本发明公开了种餐具装饰用耐碱银箔，由如下重量份的原料组成：银
