紙盒的開料

一﹑常用單位換算(紙盒制造廠一般以英吋為單位)

1吋=8分                       1吋=2.54cm         1cm=0.3937吋

1分=1/8吋                       =0.125吋                   半分=1/16吋                  =0.0625吋

2分=1/4吋                       =0.25吋                     1分半=3/16吋              =0.1875吋

3分=3/8吋                       =0.375吋                   2分半=5/16吋              =0.3125吋

4分=1/2吋                       =0.50吋                     3分半=7/16吋              =0.4375吋

5分=5/8吋                       =0.625吋                   4分半=9/16吋               =0.5625吋

6分=3/4吋                       =0.75吋                     5分半=11/16吋              =0.6875吋

7分=7/8吋                       =0.875吋                   6分半=13/16吋             =0.8125吋

8分=1吋                          =1吋                          7分半=15/16吋             =0.9375吋

二﹑紙盒開料公式

(1)   普通箱﹕

紙度=寬+高+飛邊(0.5-1)

切長=(長+寬)*2+釘條(1.5-2)                                                                                                                                                                                     例﹕20*12*14

           (折盒翼仔長主度為闊度之半)

紙度=(12+14)=26"

(因紙料由29"單數遞增至55"﹐所以26*2+0.5=52.5用53"。

切和長=(20+12+1.5)=33.5"

如果用53"*33.5"紙板做箱﹐則每張紙板只可以做1只紙箱﹐如果用53"*65.5"即(20+12)*2+1.5的紙板做箱就可以做紙箱2只。

(2)   半翼箱﹕

紙度=0.5寬+高+飛邊(0.5)

切長=(長+寬)*2+釘條(1.5-2)

例﹕20*10*8

(3)   齊翼箱

紙度=2寬+高+飛邊(0.5)

切長=(長+寬)*2+釘條(1-2)

例﹕20*12*14

(4)   天地盒

紙度﹕寬+2高+飛邊(0.5

切長﹕ 長+2高

例﹕天盒 ﹕10*9*3

地盒﹕9.5*8.5*2.75

(5)   套式盒

A﹑單插式﹕

大身﹕(2高+2寬+1.5)﹕長

橫身﹕(2寬+長+2)﹕高

例﹕12.25*9.875*4.875

B﹑雙插式

大身﹕(高+2寬+3)﹕長

橫身﹕(2寬+長+2)﹕高

 例﹕12.25+9.875+4.875
