Abstract
The present invention is a multi-layer air cushion packing material whose buffer is made of more than two layers formed into one entire layer. The main pad is installed with several raised buffering pieces. The bottom pad is piled up inside the inner pad with several raised arcs on the back board. Between the main pad and the bottom pad is the inner pad with several raised arcs on the back board and the radian of each raised arc is less than that of the buffering pieces on the main pad. With the closely piling between the buffering pieces and the raised arcs and the assistance of the air chamber, the packing material made of two or more pairs of the buffers provides buffering function through the airtight air chamber formed by the piled layers, which in turn achieves better shockproof effect and protects the product.
