Multi-Bottle and In-Store Packing

Load capacity and base construction

A still-wine bottle runs 1.2 to 1.8 kg filled. Champagne and heavy-based spirits exceed 2 kg. Your box load capacity should be at least twice the actual filled weight. If you don't do this, the base fails first. We don't guess at this; we build it into the structure.

Bases need a reinforcing card, a double layer, or an EVA or moulded-pulp tray carrying the load. Lid-and-base and drawer formats are highest risk at the base. That's where you'll see sag, tear or outright collapse. For multi-bottle boxes, we recommend a tray insert that holds each bottle at four points, never an unsupported neck or shoulder.

Our greyboard standard is 1200 g minimum, 1400 g recommended for spirits. Facing paper is 157 g minimum specialty or coated. No recycled greyboard, no high-moisture paper. This matters because a cheaper board will soften under load and in humidity. You'll feel the difference when you lift the box.

Handle failure and how we fix it

Handle failure is the most common complaint on multi-bottle boxes. You see it in the field: a torn slot, a cracked fold, a handle that pulls out of the lid. The weight of four or six bottles concentrates right at the handle position, and standard paper handles simply can't take it.

We add a folded-back paper layer at the handle position. It's a simple fix, but it changes the failure point from the slot edge to the reinforced area. The handle then carries the load instead of tearing away from it.

If you're shipping these boxes flat for in-store assembly, handle durability matters even more. Store staff will grab the box by the handle repeatedly, often with one hand. We test for that. Our in-house checks include a 1.2 m six-face drop test with bottle loaded and stacking top load 40 kg or more for 24 hours. If the handle survives that, it survives the store.

Dividers that prevent assembly errors

For in-store assembly, the divider is where errors happen. A reversed divider means bottles rattle, labels get scuffed, or the box won't close. Training helps, but structure solves it. We build in two fixes.

First, orientation arrows plus asymmetric locating tabs. A reversed divider physically will not seat. You can't put it in wrong because the tabs won't match the slots. No training needed. Second, two fold positions on one divider where a single box must take two bottle diameters, marked A and B on the reverse. One divider, two bottle sizes, no extra SKU.

The divider also works with the insert rule. Each bottle is held at four points, so there's no unsupported neck or shoulder. We check that with a 10 second shake: no movement. Tilt 45 degrees: no slide. Invert: no release. Those are the same checks we run on every insert, not a special for multi-bottle.

Window position and label verification

Window position is verified against both bottle labels, not sized from one bottle type. If you have two different wines in the same box, the window must show both labels cleanly. We check that at the design stage, not after printing.

This matters more in multi-bottle packs because the bottles sit at different heights or diameters. A window that works for one bottle may crop the other. We lay out the window against the actual bottle samples or dimensions you send. If you have a reference design, we match it; if not, we'll propose a position that shows both labels.

Colour control is part of this. Pantone matching, first-article approval, mid-run sampling. Black, deep blue and burgundy are hardest to hold. If your label has those colours, we'll flag it early and adjust the print run accordingly. You won't find out after the boxes arrive.

In-house checks before shipping

We run three checks on every multi-bottle box before it leaves. First, a 1.2 m six-face drop test with bottle loaded. That simulates a fall from a counter or a courier van that gets loaded three times before it reaches the customer. Second, stacking top load 40 kg or more for 24 hours. That simulates a pallet in a warehouse or a truck. Third, truck and sea vibration simulation, no internal movement. If a bottle shifts during vibration, the insert is wrong.

Our control tolerance is insert plus or minus 1 mm, box body plus or minus 2 mm. For foldable boxes: creases must not crack, magnet position plus or minus 1 mm, corners 90 degrees when erected. These are not aspirational numbers; they're what we measure against on the line.

If you're packing in store, the box arrives flat. We check the creases and the fold positions before packing. A crease that cracks on the first fold is a failed box. We don't ship those.

When this solution is the wrong choice

If you need a single-bottle gift box with a high-end finish, this page is not for you. Multi-bottle and in-store packing prioritises structure and cost. A rigid lid-and-base box with a velvet tray is a different job. We make those too, but the specs differ.

If your bottle is unusually shaped, like a bulbous Burgundy or a tall Riesling, the divider and window logic changes. You may need a custom insert rather than a standard divider. We'll tell you that after seeing the bottle.

If you're shipping direct to consumer in small parcels, a corrugated shipping box with a single-bottle insert is often better than a multi-bottle display box. The loads are different, and so are the failure modes. We'll help you pick the right structure for the job.

Specifying the job

To start, send box dimensions or bottle sample, reference design, quantity, special requirements. We'll confirm the structure, divider type, handle reinforcement and window position. Two sample types: blank sample for structure, printed sample for visual. Blank sample first, then printed. That way you can test the fit before paying for print.

Payment is T/T or PayPal. Shipping by air, sea or express. We'll quote based on your quantity and destination. No hidden fees on samples; we'll tell you the sample cost upfront.
