Lid and tray two piece box. For larger and heavier items, the double over folds and full depth lid create extra strength and stability. The double thickness wall on the length / width gives this box strength under compression and can be happily stacked. As the lid covers the full depth of the tray, the box has 3 layers of vertical board when closed. Suited to long term storage. Larger sizes available in this style.
Particular care needs to be taken with the double crease, it is essential that the crease closest to the interior of the box (shown in green) is folded first.
