Abstract: A paper structure is disclosed, which comprises: a paper substrate; an adhesive layer, formed on the paper substrate; and a polymer layer; wherein the polymer layer is configured with a plurality of embossed elements and is disposed on the adhesive layer for allowing the spaces formed between the embossed structures and the paper substrate to be filled by the adhesive layer. In addition, the flexibility of a carton box that is formed using the aforesaid paper structure can be enhanced through the cooperation between the embossed structures and the adhesive layer filled inside the recesses of the embossed structures, and thus the ability of the carton box to absorb collision impact can be improved.
