The code shall consist of a number placed inside a triangle and letters placed below the triangle. The triangle shall be equilateral, formed by three (3) arrows with the apex of each point of the triangle at the midpoint of each arrow, rounded with a short radius. The pointer or arrowhead of each arrow shall be at the midpoint of each side of the triangle with a short gap separating the pointer from the base of the adjacent arrow. The triangle, formed by the three (3) arrows curved at their midpoints, shall depict a clockwise path around the code number. The numbers and letters used shall be as follows: 1 = PETE (polyethylene terephthalate)
2 = HDPE (high density polyethylene)
3 = V (vinyl)
4 = LDPE (low density polyethylene)
5 = PP (polypropylene)
6 = PS (polystyrene)
7 = OTHER (represents all other resins, including layered plastics of a combination of materials).
