Tubular box structural design

The theory of carton box design is a little complicated, In this article we will talk about the structural design formula and some commonly tubular box structure.

Size	E	EX	B4	V	FX
D＝Caliper
<0.45mm	B-D	D	B-D	D	D
046－0.65mm	B-D	D	B-D	D	D
0.66－0.99mm	B-D	D	B-D	D	D
1.00-1.80	B-D	D	B-D	D	D
Size	ZX	Z4	YH	S	N	FS
D＝Caliper
<0.45mm	3	3	D+0.5	D	F/4 mm	D
046－0.65mm	3	3	D+0.5	D
0.66－0.99mm	3	3	D+0.5	D
1.00-1.80	3	3	D+0.5	D

Note: When FX and Y equal 0, E=B

A	17mm<=A<=30mm	30mm	100mm	A>150mm
	F=10mm	F=13mm	F=15mm	F=18mm

Structure of the end of the tubular folding carton box

1、Tuck end

2、Lock-End

3、Self Lock End

4、Glue End
