The bottom of the plastic packaging box of frozen food sold in the supermarket is pressed with some concave convex grooves with geometric patterns, which is mainly to a reduce the friction B enhance the anti deformation ability C, which is light and beautiful d avoid food contamination

the plastic used to make the packing box has little mechanical strength. In order to prevent the breakage and damage of the packing box, some geometric patterns are often pressed at the bottom of the box to increase the mechanical strength of the packing box.
the concave convex grooves of some geometric patterns are helpful to strengthen the mechanical strength of the box bottom and enhance the deformation resistance of the box bottom.
so choose B

for verification or anti-counterfeiting marking!

if there are multiple choices, you can choose B and C
