Paper string reticulated structure

Abstract

A paper string reticulated structure includes a paper string made from a base paper containing soft wood kraft pulp as a main raw material. A vegetation net, an agricultural net, a construction net, and an article container such as a shopping bag, cloth basket, and vegetable basket can be made from the paper string reticulated structure.
