Multi-Bottle and In-Store Packing

Load and Base Structure

A still-wine bottle runs 1.2 to 1.8 kg filled. Champagne and heavy-based spirits exceed 2 kg. That means the box load capacity should be at least twice the actual filled weight. A 4-bottle box holding bottles at the top of that range needs a base that carries the full load, not the empty box weight. We design to that target.

Lid-and-base and drawer formats are highest risk at the base. The weight sits on a flat panel that gets lifted, slid, and stacked. So the base gets a reinforcing card, a double layer, or an EVA or moulded-pulp tray carrying the load. We do not rely on the outer wrap alone. For our rigid boxes, the greyboard is 1200 g minimum, and 1400 g is what we recommend for spirits or anything over 2 kg per bottle.

The insert matters too. Bottle held at four points, no unsupported neck or shoulder. That rule applies to multi-bottle trays as well as single-bottle inserts. A bottle that can rock inside the box will transfer load to the side walls during handling, and the base will fail at the corner.

Handle Failure

Handle failure is the most common complaint on multi-bottle boxes. A 6-bottle box can weigh 10 kg or more. The handle is a die-cut hole or a folded paper grip, and it gets pulled by a customer who does not think about it.

We add a folded-back paper layer at the handle position. That is a double thickness of the facing paper, folded over the cut edge and glued down. It spreads the load across a wider area and stops the paper from tearing at the fold. You can feel the difference immediately.

If the box will be carried more than a few meters, or if it is a seasonal pack that gets moved from stockroom to floor repeatedly, tell us. We will spec the handle reinforcement and test it with the actual filled weight.

In-Store Assembly and the Divider

For in-store assembly, the divider is where errors happen. A store employee has thirty seconds, not five minutes. If the divider can be put in backwards, it will be. And then the bottles do not fit, or they rattle, and the box comes back.

Two fixes we build in. First, orientation arrows plus asymmetric locating tabs. The tabs are offset left and right, so a reversed divider physically will not seat. Structure solves it, not training. Second, two fold positions on one divider where a single box must take two bottle diameters. The positions are marked A and B on the reverse, so the same divider works for a Burgundy bottle and a Champagne bottle. No extra parts, no separate dividers.

We prototype this with the actual bottle diameters you specify. The divider is cut to your bottle, not to a generic template. Our insert tolerance is plus or minus 1 mm, and the box body is plus or minus 2 mm.

Window Position and Label Fit

Window position is verified against both bottle labels, not sized from one bottle type. If your pack holds two different varietals, or a still wine and a sparkling, the window has to work for both. A window that shows the shoulder of one bottle and the label of the other looks wrong on shelf.

We ask for bottle samples or label dimensions early. The window is cut after the insert is fixed, because the insert determines where the bottle sits. Then we check the view with a filled bottle, not an empty one. The label position shifts when the bottle is full.

For a windowed corrugated carrier, the same rule applies. The window is not a decoration. It is a display feature that has to line up with the label every time. We print a first article and check it against both bottle types before we run the full quantity.

Fit and Movement Checks

The insert rule is simple: bottle held at four points, no unsupported neck or shoulder. But the real test is movement. We shake the box for 10 seconds. No movement. We tilt it 45 degrees. No slide. We invert it. No release.

Those are our in-house checks, not a lab test. They are done with the actual bottle, filled, in the actual box. If a bottle moves, the insert is wrong, and we fix it before production.

For multi-bottle packs, we also check that the bottles do not touch each other. A 4-bottle box with bottles touching will rattle and scuff labels. The divider has to create a gap, and that gap has to survive the drop test.

Pre-Shipment Checks for Multi-Bottle Packs

Before a multi-bottle pack ships, we run three checks. First, a 1.2 m six-face drop test with the bottle loaded. That means the box is dropped on all six faces, from 1.2 meters, with the actual filled bottle inside. It has to survive without structural failure and without the bottle moving.

Second, stacking top load. We put 40 kg or more on top of the box for 24 hours. That simulates a pallet in a warehouse, not a shelf in a store. The box has to hold its shape, and the insert has to keep the bottle in place.

Third, truck and sea vibration simulation. We run the box on a vibration table that mimics road and ocean transport. No internal movement. If the bottle shifts during vibration, the insert is not tight enough, and we adjust it. These are our in-house checks, done on every new structure before mass production.

When This Is the Wrong Choice

Multi-bottle and in-store packing is not for every job. If you need a single-bottle gift box with a velvet tray and a magnetic closure, this page is not for you. That is a different structure with different priorities. A multi-bottle pack is about load, stacking, and operator handling. If those are not your constraints, you do not need this solution.

It is also the wrong choice if your pack is assembled by the end customer at home. In-store assembly means the operator is not the buyer. The box has to be foolproof, and that adds a little cost. If the customer assembles it, you can use a simpler divider because mistakes are less likely to be returned.

And if you are shipping bottles in the box, not just displaying them, tell us. A display box is not a shipping box. We can add a corrugated outer or a reinforced base, but that changes the structure. Do not assume a rigid box will survive courier handling without testing.
