A tube length has to clear the roll. A square box crushes it or fills the corners. This page stays with double wall boxes, next to white postal boxes.
Packaging Boxes keeps Double wall boxes apart from a larger single wall box. The range is also the removal board. It is listed apart from single wall.
What this collects
Double wall is the stronger board, made in the UK, for heavy, fragile or stacked goods.
white postal boxes is the neighbour on this list. White postal boxes are the white finish for a parcel that is meant to look like post, not like a warehouse carton. It is still a different range from double wall boxes.
Before the order goes in
Choose double wall for the weight or the stack, then the size. Do not choose it only because it sounds safer for a light item.
A Packaging Boxes basket with Double wall boxes still leaves the same day if it is placed by 3pm. The terms aim for 5.30pm the next working day. A 1 to 3 day courier is also described, depending on the lines.
