The present invention relates to a shock-absorbing packaging material having a multi-layer air cell. More specifically, at least one or more auxiliary inner covers alternately and partially fused with a pair of outer covers are provided between the outer covers configuring an air cell of the shock-absorbing packaging material to form the air cells of a multi-layer structure alternately stacked inside the outer covers. As such, the present invention improves shock-absorbency through the air cell of the multi-layer structure to protect more safely a product when the product is packaged using the shock-absorbing packaging material. Moreover, the present invention effectively blocks heat transmission between the inside and the outside of the packaging material through a portion where the air cells are connected to each other through the alternately stacked air cell structure of the multi-layer structure in order to have the multi-layer air cell be useful for packaging the product requiring heating and cooling functions. |
