Unless otherwise specified (see 6.2), nominal thickness shall be 0.004 inches.

Finish shall be No. 2 (treated).
3.3 Construction. Class A, B, C, and E bags shall be formed using two sheets or by folding
one sheet of material. Heat-sealable surfaces of the specified material shall be placed face to face,
heat-sealing along both sides and the bottom edge as required. Transparent bags fabricated by the
side weld process shall be folded and have two side seams. The side seams shall be parallel to
each other and to the outer edges of the bag in all cases. The bottom fold shall be at right angles
to the side seams. Class F and H bags shall be formed from one folded sheet of material heat-
sealed on three sides (fold shall be heat-sealed).
3.3.1 Notched bags. When specified (see 6.2), bags shall have a tear, nick, or V-notch
1/8 inch deep with a tolerance of ± 1/16 inch, in at least one edge located 1 to 1-1/4 inches from
the open (unsealed) end of the bag. The legend "TEAR HERE TO OPEN" with an arrow
pointing to the tear, nick, or V-notch shall be printed on the bag with lettering that shall be not
less than 1/8 inch in height.
3.4 Dimensions and tolerances. The length and width of bags shall be specified in the
contract or purchase order (see 6.2). The width shall be measured from the inside edges of the
side seams. The length shall be measured from the inside edge of the bottom seam or bottom
fold to the edge of the opening. The tolerances for the length and width shall be as indicated in
table II. The maximum heat-seal widths shall be as indicated in table II.
