Die-Cut Bin Boxes and Pick Bins: A Buyer's Guide

What is a die-cut bin box?

A die-cut bin box is an open-front or open-top corrugated bin, cut and creased from a single flat blank so it folds into shape and locks without tape or glue. You may know it as a pick bin, a stackable bin box, or a KLT-style corrugated bin. The open face is the point: a picker reaches straight in and takes the part, no lid to lift, no flap to fight. It replaces the plastic bin on a shelf with a lighter, cheaper, recyclable version cut to your exact shelf.

Because it is die-cut rather than slotted, the shape is not limited to a plain box. The die can add a scooped front for easy reach, finger holes for pulling the bin out, a label window on the face, and self-locking tabs that hold the walls square under load. It ships flat, so a thousand bins take a fraction of the storage of pre-formed plastic totes, and your team folds them as the shelves fill up.

This guide is buyer-side. It covers where these bins earn their place, how to size them to the bay and to the SKU, when 3-ply is enough and when you need 5-ply, plain versus printed labels, the one-time die cost, and the order quantity reality. The aim is a brief you can hand us that prices in one pass.

Where are die-cut bin boxes used?

Anywhere small items live on a shelf and get picked by hand. The open face suits high-frequency picking, and the flat-pack format suits any operation that wants to scale bins up or down without buying moulded plastic. The common homes are below.

• Warehouse pick faces: one SKU per bin along a pick line, sized so the bin fills the shelf pitch and the picker reads the label at a glance.
• Shelf and rack storage: back-stock and slow movers held in uniform bins that stack and index cleanly on standard racking.
• Workshop and parts stores: fasteners, fittings, spares and small components sorted into labelled bins at the bench.
• E-commerce fulfilment: returns sorting, kitting stations and small-SKU buffers where plastic totes are overkill.
• Retail stockrooms: accessories, sachets and small-carton goods held tidy behind the shop floor.

The pattern in every case is the same. Many identical bins, sized to one shelf bay, holding one SKU each, pulled open-front by hand many times a day. That repetition is what makes a die worth cutting: the per-bin saving over a plastic tote, multiplied across a full rack, pays back the tooling fast.

A die-cut bin is not a box you close; it is a shelf position you pick from, so it is sized to the bay, not to the parcel.

How do you size a pick bin?

Size in two passes. First to the shelf, then to the SKU. Start with the shelf bay, because a bin that does not fit the pitch either wastes space or fouls the shelf above. Measure the clear width, the usable depth, and the height between shelves, then divide the width into a whole number of bins so a row fills the bay with no dead gap. Leave a few millimetres of finger clearance between bins so a picker can lift one out without dragging its neighbours.

Then check the SKU. The bin has to hold a sensible quantity of the part, front-load with the reach you want, and keep the label face clear. For deep bins on a low shelf, a scooped or stepped front lets the hand reach the back without tipping the bin. For tall parts, an open-top bin indexes better than an open front. All figures you brief are internal, the clear space inside; the die and the ply decide the outside footprint.

These are working sizes, not a fixed catalogue. Because the bin is die-cut, the size can be whatever your bay and SKU need. Nesting and stacking follow from the size too: cut the bins so empties nest inside each other for storage, and so full bins stack square without crushing the one below. If your racking is a known standard, tell us the shelf pitch and we work back to a bin count that fills it cleanly.

3-ply or 5-ply: which do you need?

Ply is the count of paper layers in the board, and for bins it is a load-and-life decision, not a shipping one. These bins mostly sit on a shelf, so the question is how heavy the contents are, how tall the bins stack, and how many times a day a hand pulls on the open front. Light parts on a single shelf are happy in 3-ply. Heavy parts, tall stacks, or a hard-worked pick line want the extra wall of 5-ply.

A quick way to decide: if a full bin is light enough to lift one-handed and it never carries another bin on top, 3-ply is usually enough. If it is heavy, or bins stack, or the same bin gets pulled open hundreds of times a week, step to 5-ply so the front does not soften and sag. When a run mixes both, we often cut the heavy-SKU bins in 5-ply and the rest in 3-ply, priced as two lines on one order.

Plain or printed labels?

The label face is where a bin earns its keep on a pick line, and you have three routes. Plain kraft bins with a stuck-on label pocket are the cheapest and the most flexible: you print labels in-house and swap them as SKUs move. A printed label window die-cut into the face lets you slide a card in and out without adhesive. Or the label prints directly on the board, one colour, for bins that hold a fixed SKU that will not change.

For most warehouses the plain bin with your own label wins, because SKUs rotate and a printed bin locks the position. Direct print makes sense for permanent fixtures, colour-coded zones, or branded bins seen by customers, for example at a kitting or returns station on a fulfilment floor. Keep print to one or two colours: it is cheaper and reads faster across an aisle than a busy design.

The die cost and order quantity

A die-cut bin needs a die, the cut-and-crease tool that stamps the shape. That is a one-time cost per unique bin shape, not a per-bin charge, and it is quoted on WhatsApp once we know the bin outline and features. After the die exists, reorders of the same bin skip the tooling and price on board and conversion alone, so the first order carries the die and every order after is cheaper per bin.

That tooling is why bins run to an order quantity. A minimum order spreads the die across enough bins to keep the per-bin price sensible; a tiny run makes the tooling dominate the unit cost. If you need a handful of bins to trial a layout, say so and we look at whether an existing die fits or whether a slotted stand-in works for the pilot. Once the layout is proven, the full run on a dedicated die is where the price drops.

Worked feel for the numbers: on a standard shelf bin, board and conversion might land a bin in a band of Rs 14 to Rs 26 each at volume, with the die a separate one-time line on top. The board figure moves because recycled kraft is a traded material whose rate sits in a market band. Prices attract 5% GST (HSN 4819); a GST invoice is issued with every order.

The die is a one-time cost you pay once and reuse on every reorder, so bins get cheaper the longer you run the same shape.

If your bins carry inserts, dividers or trays inside, we cut those on the same brief. Our die-cut trays and inserts capability handles partitioned bins, slotted dividers and fitted trays that turn a plain bin into a sorted one, so a single order can deliver the bin and its internal layout together. Send the shelf dimensions, the SKU, a rough quantity, and whether you want plain or printed, and we price the die and the bins in one pass, factory-direct from NCR.
