What is Triangular carton, glued ends?

Triangular carton, glued ends is a sleeve, wrap or slide carton. A three-sided tube where every wall carries a full triangular end flap, so the three overlap and glue into a closed, dust-tight end. Erected and filled on an automatic machine.

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.
