x9x (thickness 2 mm) means e pit (juvenile pit) x3x (thickness 3 mm) - - represents a single layer.
x = x (thickness 6 mm) - - double x x (thickness 9 mm) - - three layers

flat paper in the middle layer - ordinary paper without representation. w - means white paper.
single pit (paper) double pit (paper) three pits (paper) juvenile pit (paper)
c33 b = 3 b_b 9b
b33 b = cb_c b9c
b3c b = b b_3 a9a
b3b a = b a_b a9b
a3b a = a_a w9a
w3b w = b w_b w9b
b. selection of cartoon box materials:
usually b = b, the thickness of paper is about 6mm. this material is the lowest. if customers have requirements, a = b can also be used. this material has better strength than b = b and higher price. a = a paper is better than a = b and b = b. the thickness is 6mm and the price is higher, unless special requirements are selected.
