Custom Snap Lock or 123 Bottom Boxes
Custom snap lock boxes have four base flaps that interlock as you fold them, so the base holds square without any glue or tape. Folding takes a few seconds by hand, but with no pre-gluing step it costs less than an auto bottom; below several hundred boxes daily, that saving usually wins out. The base performs equally well in kraft, coated cardboard or corrugated stock.

A Base That Stores Flat and Locks When You Need It
Storage space never appears on a quote. A snap lock carton arrives as a flat sheet, sits in a stack until a batch is ready, then takes its shape with a locked floor underneath. That suits businesses holding weeks of packaging in a small back room.
Custom snap lock boxes are bought by bakeries, food counters, confectioners and retail brands whose products are too heavy for a tucked base but whose order volume doesn't justify a glued one. The style is the constant here. The board under it changes with the job, from coated stock for shelf color to fluted board for heavier contents, so you settle the base once and then pick the stock each range actually needs.
Snap Lock Build Sheet: Flaps, Stock Options and Fit
Every snap lock base uses the same four-flap geometry. What varies is the stock, its thickness and how closely the box is cut to the product.
| Spec | Snap lock options |
|---|---|
| Base | Four interlocking flaps, no glue or tape |
| Coated cardboard | SBS, 14–24pt |
| Kraft | 14–18pt for light items, 18–24pt where the base carries more |
| Corrugated | C-flute, B-flute or BC double-wall |
| Tolerance | ±0.5–1mm on folding board, ±1/16" on corrugated |
| Sizing | Cut to your product's internal dimensions |
Most folding-board orders sit in the coated range. When a box carries real weight or gets stacked, the same base moves onto fluted board for the heavier snap lock runs, where the flute takes load the flaps can't carry alone.
Hand-Folded Flaps or Glue: Where Snap Lock Wins
A glued auto bottom opens faster, but every unit carries a gluing step in its price. A snap lock asks for a few seconds of folding instead, and that trade suits businesses whose packing happens in bursts rather than on a moving line. Staff can fold a stack during the quiet hour before opening, then fill boxes through the rush without reaching for a tape gun.
That pattern fits whole cakes boxed at the counter particularly well. The base has to hold a dense product, yet a shop selling a few dozen cakes a day never makes the gluing premium back. Where snap lock loses is the opposite case: a line packing thousands of units a shift, where folding time adds up faster than any saving on the board.
Printing a Box Whose Base Is Folded by Hand
The bottom panels are the most handled surface on this box and the least seen, so keep detailed artwork off them. A logo printed across the flaps gets sliced up by the interlock anyway, since each flap shows only a section of it. Put the design on the four walls and the lid.
What's available follows the stock. Coated board takes full color with matte or gloss lamination. Kraft suits one or two colors. Corrugated takes bold flexo artwork, with thin lines left out because the flute blurs them. Foil and spot UV are worth it on coated board when the box sits on a shelf. When it's filled behind a counter and handed straight over, skip them; nobody studies a cake box on the walk to the car.
Who Folds Their Own Bases Every Day
Snap lock bases turn up wherever a product is heavier than it looks and gets packed by hand in batches. Bakeries fold them for pies and tray bakes. Delis and caterers use them for prepared food sold by the box, from boxed lunches to platters collected for an office meeting. Popcorn sellers use the larger formats, where a tuck end would open under a full load.
Confectioners rely on them for assortments too heavy for a tucked bottom. Gift brands use them for hampers built up layer by layer, where the floor has to stay put while the box is filled. The common thread is weight plus manual packing: enough load to need a locked base, but not enough daily volume for a glued one to pay for itself.
From Dimensions to a Dieline You Sign Off
Send us the product's measurements and we'll draw the dieline around them, confirming in writing whether each figure is internal or external. On a base that has to interlock, a dimension taken from the wrong side of the board is the difference between flaps that seat and flaps that fight each other.
Die, plates and setup are in the quote. Once you sign off the proof, production takes 8–12 business days. Rush is available at an extra cost we give you upfront. Each order passes a three-stage check before it leaves us, and the base lock is part of it, so flaps that don't seat are caught on our side rather than at your counter. Shipping is included.

How does a snap lock base work?
Four base flaps interlock as you fold them, so the base holds itself square without glue or tape. You fold it yourself, which takes a few seconds but costs less than a pre-glued auto bottom.
Can snap lock boxes be made in any stock?
Yes. Snap lock describes the base construction rather than the material, so you can have it in kraft, coated cardboard or corrugated depending on the load and the look you need.
Is snap lock cheaper than auto bottom?
Yes, since there's no pre-gluing step. The trade is assembly time — your team folds the base rather than popping it open. Below a few hundred boxes a day that saving is usually worth it.
How long do snap lock boxes take?
Most orders are ready in about 8–12 business days once you approve the proof. Rush production is available at an extra cost, quoted upfront, with shipping included.
What's the minimum order for snap lock boxes?
100 boxes, across every stock. That's low enough to trial a snap lock base against your current build before switching a range over, and design help is unlimited and free.
