<p>PROBLEM TO BE SOLVED: To obtain a net having no extractable material and a very thin net having uniform size and shape of holes by incorporating a lattice of polymeric material defined by the holes traversing the integral net from one surface to the other. SOLUTION: A polymer lattice 13 of the integral net 12 is formed in a net- like structure via holes 11. Thus, the net 12 preferably contains the lattice 13. Its structure is defined by the holes 11 traversing the net 12 from one surface to the other. The lattice 13 may be regularly arranged according to disposition of the holes 11, or irregularly arranged. The lattice 13 may be constituted of most of an area of the net according to a size of each of the holes 11 or constituted of small part of the area of the net.</p> |
