Multi-Bottle and In-Store Packing

Load comes first

A filled still-wine bottle runs 1.2 to 1.8 kg. Champagne and heavy-based spirits go past 2 kg. So we size the box for at least twice the actual filled weight. That is not a safety margin for the shelf. It is for the moment someone picks the pack up by one corner, or a courier drops it on a concrete floor.

The base is where most multi-bottle boxes fail. Lid-and-base and drawer formats are the highest risk because the base takes the full load on its own. We fix that with a reinforcing card, a double layer of board, or an EVA or moulded-pulp tray that carries the bottles instead of letting them sit on the bottom panel. The tray is usually the cleanest fix. It spreads the weight and stops bottles knocking each other in transit.

If you are not sure which base construction you need, send us the bottle weight and the number of bottles. We will tell you what we would build, and why.

Handles that do not tear

Handle failure is the most common complaint on multi-bottle boxes. The paper tears at the fold, or the handle pulls out of the top panel. We add a folded-back paper layer at the handle position. That doubles the material at the stress point without making the rest of the box heavier or more expensive.

For a wine bag, the handle is the whole suspension system. Felt and canvas bags get a stitched or riveted handle, never just glued. Paper bags use a twisted or flat paper cord with a reinforced patch behind the anchor points. If the bag is meant for two bottles, we test it with two filled bottles, not one.

Tell us how the pack will be carried: by hand, on a shoulder, or in a shopping bag. That changes the handle spec.

Dividers that cannot go in wrong

In-store assembly is where dividers cause the most errors. A reversed divider means the bottles do not fit, or they rattle, or the pack looks wrong on the shelf. Training helps, but structure is more reliable. We build in two fixes.

First, orientation arrows plus asymmetric locating tabs. If the divider is reversed, the tabs will not seat. The person assembling the box does not need to read anything. They feel it does not fit, flip it around, and it drops in. Second, when one box must take two bottle diameters, we put two fold positions on one divider, marked A and B on the reverse. No second divider to lose, no guesswork.

This matters most in seasonal rushes and retail back rooms. The person packing may have been hired three days ago. The pack has to work anyway.

Windows checked against both labels

A window looks simple until you put a different bottle in the same box. We verify the window position against both bottle labels, not sized from one bottle type. If the pack is for a 750 ml Bordeaux and a 750 ml Burgundy, the label height and shoulder shape differ. The window has to work for both, or the customer sees a cropped label.

We also check the window film. A PET window is standard, but it scuffs in transit. A matt or anti-scuff film costs a little more and keeps the pack looking fresh on the shelf. If the box is for a windowed corrugated carrier, we use a die-cut opening with no film, or a film patch applied after printing.

Send us both bottle labels, or the bottle dimensions and label position. We will size the window from that.

What we control in production

Our control tolerance on inserts is plus or minus 1 mm. Box body is plus or minus 2 mm. For foldable boxes, creases must not crack, magnet position is plus or minus 1 mm, and corners sit at 90 degrees when erected. Those are the checks that catch most multi-bottle failures before they leave the factory.

The insert rule is simple: a bottle is held at four points, with no unsupported neck or shoulder. Then we check it three ways. Shake the pack for ten seconds, no movement. Tilt it 45 degrees, no slide. Invert it, no release. If a bottle moves in any of those, the insert is wrong.

Colour control matters on seasonal packs. Black, deep blue and burgundy are the hardest to hold. We match Pantone, approve a first article, and sample mid-run. If the pack is a Christmas wine bag, the red has to match across thousands of units and two production batches.

Pre-shipment checks we run in-house

Before packing, we run our in-house checks with the actual bottle loaded. A 1.2 m six-face drop test. Stacking top load of 40 kg or more for 24 hours. Truck and sea vibration simulation with no internal movement. These are the checks we run on every multi-bottle order.

If the pack fails, we adjust the structure, not the test. That is the point of running them. A base that collapses under 40 kg in the warehouse will collapse in a container stack. Better to find it here.

For in-store packing, we also check assembly time. If a pack takes more than about 30 seconds to erect and fill, it is too slow for a retail back room. We time it during the sample stage and simplify if needed.

When this solution is the wrong choice

If the pack is a single luxury gift for a high-end wine, a multi-bottle solution with a divider and a load-bearing base is overbuilt. You are paying for structure the customer never sees. A rigid lid-and-base box with a velvet tray is the better call.

If the pack is shipped flat and assembled by the end customer at home, the in-store assembly fixes are wasted. Orientation arrows and asymmetric tabs help a retailer, not a consumer. In that case, a simpler foldable box with a clear instruction card is enough.

And if the bottle weight is under 1 kg, or the pack holds only one bottle, the doubled handle and reinforced base are unnecessary. This solution earns its cost from two bottles and up, or from any pack that gets stacked and handled hard.
