A category manager asks whether the pack can hang, and the answer decides shelf position before a single word of the artwork is discussed. Two tools put a box on a peg: a slot cut into the board, and a tab glued on. Choosing between them – or combining them – is a small decision with a visible effect on cost, on pack strength and on how the box behaves after eight weeks on a hook.
What is a euro slot? A die-cut opening – the familiar round-top keyhole – cut through the board at the top of the box, letting the pack hook straight onto a peg or rail. It adds no material and no application step, only a shape on the die. Its limits are structural: the slot removes board where the pack needs it, so a heavy product on a thin board tears around the slot, and a clumsy shape distorts the hanging angle.
What is a self-adhesive hang tab? A pre-made plastic or reinforced paper tab, glued to the top of the box after filling or during finishing. It carries weight better than a slot in thin board, sits exactly where the retailer wants it, and can carry a hole positioned to balance an uneven pack. Tabs add a purchase cost and an application step, and the adhesive has to survive the shelf environment – a tab that drops off in a warm aisle is a returned pallet.
When is a slot the better choice? Light products on stiff board. A slot keeps the packaging a single material, which keeps recycling claims clean and avoids a second supplier. It also survives automated handling better than a protruding tab. If the pack weighs little and the board is rigid, ask for the slot first and test it; the article on board weight versus stiffness explains why two equal-weight boards can hang differently.
When is a tab the better choice? Heavier products, thin or corrugated board, and packs whose centre of gravity sits away from the top. Reinforced tabs – plastic or fibre-backed – carry loads a board slot would tear out of, and fold-over designs wrap over the top edge to spread the load. Retail programmes that specify exact hole positions for their peg systems usually end up on tabs for this reason, even on light packs.
Do retailers test hanging packs? They do. Common checks are a static hang test for a defined period, a tear test around the slot or tab, and an appearance check after hanging to see whether the pack distorts or the front face buckles. Some vendor manuals name the test and the duration; where they do, that document wins over any general guidance here. A pack that fails the hang test usually fails at the reinforcement point, not at the adhesive.
How does hanging change the box structure? The top panel carries the load, so creases, seams and openings move away from it. A top-opening design and a euro slot fight for the same board; a front-opening or end-loading structure leaves the hanger undisturbed. Where the pack is a carton with a printed sleeve or a label, the hanger position needs to survive the finishing steps too, which is a question about the finishing route described in the guide to printing finishes.
What should I send when specifying a hanging pack? The product weight, the board, the retailer’s peg system or vendor manual page if you have it, and the expected hang duration. Whether the answer is a slot, a paper tab or a reinforced plastic one falls out of those facts quickly, and sampling settles the rest.
If a range is moving to pegged display and the hanging method is open, send the pack weight and the board you plan to use. We will tell you what we would cut and what we would apply at our Wuhan plant, and what the trial should check. Start on the quote request page.
Chengtop produces retail packaging cartons, folding cartons and printed retail labels and hang tags at our plant in Wuhan, with hanging structures quoted as part of the dieline rather than an afterthought. Message us with the product weight and peg system.
