The invention provides a degradable food preservation pad capable of inhibiting bacteria, preventing vibration and absorbing moisture as well as a preparation method thereof. The preparation method ofthe degradable food preservation pad capable of inhibiting bacteria, preventing vibration and absorbing moisture comprises the following steps: spraying a natural antibacterial agent onto surface ofan antibacterial polylactic acid (PLA) / starch foamed material; and then, coating the antibacterial PLA / starch foamed material with a perforated polylactic acid film, thereby obtaining the degradable food preservation pad capable of inhibiting bacteria, preventing vibration and absorbing moisture. The degradable food preservation pad capable of inhibiting bacteria, preventing vibration and absorbing moisture provided by the invention has both internal and external antibacterial effects, so that an internal antibacterial agent can be slowly released while an external antibacterial agent rapidlyfunctions by volatilization or contact with a food; and thus, the degradable food preservation pad synchronously has timely antibacterial effects and long-lasting antibacterial effects. The degradablefood preservation pad capable of inhibiting bacteria, preventing vibration and absorbing moisture has broad-spectrum antibacterial capability, and is capable of inhibiting propagation of microorganisms, reducing food spoilage and prolonging product storage lives; and moreover, the degradable food preservation pad also has water absorbing and vibration preventing effects, so that quality of the products can be ensured. In addition, the degradable food preservation pad capable of inhibiting bacteria, preventing vibration and absorbing moisture provided by the invention is an all biodegradable material which is green, safe and environment friendly; and thus, the degradable food preservation pad has very broad application prospects.
