What is Vertical support strut?

Vertical support strut is a folding carton with a glued side seam, closing at each end with a tuck, a lock or a glued flap. A closed square tube standing inside a carton to carry the stacking load off the contents. Cut from the same board as the box and glued into a post.

Uses

Retail and gift packaging, where the box is seen by the customer
High-volume packing lines, since a pre-glued blank erects in one movement

Advantages

Cut from a single blank, so there is one tool and one part to stock
Arrives glued and flat, and erects quickly by hand or by machine

Disadvantages

The glued joint sets the minimum order — short runs are rarely economical

Typical industries

General packing and light manufacturing

Recommended board grades

Folding boxboard or solid bleached board, typically 250–450 microns. Heavier board for larger cartons, lighter where the carton is filled by machine.
