Should a Soap Box Window Be Open or Covered With Film?
Choose an open window for bars that are still curing and a PET film window for bars that will sit on a retail shelf.
| Option | Protection | Airflow for curing bars | Dust | Cost order |
|---|---|---|---|---|
| Open die cut window | Board on every face except the opening | Full airflow, suits bars still curing | Reaches the bar | Lowest |
| PET film window, 150 to 250 micron | Film stops fingers and scuffs | Little airflow, add vent holes for fresh bars | Kept out | Middle |
| Full clear PET box | Covers every face, brand goes on a label | None, fully cured bars only | Kept out | Highest |
Clear soap boxes show every face of the bar and suit melt and pour or fully cured bars. Clear soap packaging does not hold direct print well, so your brand goes on a sleeve or a label. After you pick the window type, its size and position decide how much label space remains.
How Big Can the Window on a Soap Box Be?
The window can run to within 6 mm of every fold and edge, so each panel keeps a frame of board around the cut. The 92 x 67 x 27 mm box for a 4 oz bar fits a front window up to 80 x 55 mm.
A cosmetic soap must show net weight in ounces and grams in the bottom 30 percent of the front panel. We stop the cut 21 mm above the bottom edge in that case, which leaves a window of 80 x 40 mm. Size settled, the shape of the cut is the part a shopper notices first.
Which Window Shapes Work Best on Soap Boxes?
Rectangles, circles, ovals and arches cut cleanly on soap boxes with window panels of any size. A leaf or logo outline works too when no strip of board between two cuts is thinner than 6 mm.
A circle window on square soap boxes frames a round stamp in the center of the bar. Makers of custom handmade soap boxes match the window to the bar, such as an arch over a loaf slice. A fancier cut raises a fair question about strength, which the next answer covers.
Does a Window Make a Soap Box Weaker?
A single window on the front panel does not make a soap box weaker in a stack, because the four side walls carry the load. Strength drops when a cut crosses a fold or opens two facing panels at once. With the window planned, placing the order takes only a few details from you.
