Choose multi depth cardboard boxes when you pack products of different heights. Horizontal score lines let you reduce the box depth for a closer fit. This helps limit empty space, use less filling and keep fewer box sizes in stock.
These multi-depth cardboard boxes combine an adjustable height with the strength of double wall board. They suit ecommerce orders, warehouses, distribution centres and businesses with changing packing needs.
Each box has score lines at fixed heights. Place your product inside and select the nearest score above it. Cut the corners down to that line, fold the sides and seal the box.
The length and width remain the same. Only the height changes. This gives you several packing depths from one box size.
One box, multiple heights. Multi-depth boxes can reduce void fill, help lower parcel volume and allow you to keep fewer carton sizes in stock.
A double wall cardboard box uses two fluted layers between three liners. This double flute corrugated construction offers more strength than a standard single wall carton and is well suited to heavier, fragile and multi-item orders.
Ecommerce & fulfilment: ideal for pick-and-pack operations where order heights change from one shipment to the next.
Tools, components & small appliances: double wall construction provides additional support for denser products.
Fragile homeware: adjust the carton height while leaving enough room for suitable protective cushioning.
Multi-item orders & returns: create a closer fit around changing product combinations and help reduce movement.
Warehouse picking & packing: fewer carton sizes can simplify stock management, purchasing and packing operations.
Pallet loads: maintain a consistent length and width while adjusting the height to suit different loads.
Adjusting the height creates a closer fit around your products. Less empty space means you may need less void fill or other protective material.
One adjustable carton can replace several fixed-height cardboard boxes. This simplifies ordering and frees up valuable storage space.
Double wall board provides better support for heavier, fragile or multi-item orders. It also handles stacking and repeated movement more effectively.
Using fewer carton sizes can make purchasing and storage more cost effective. A closer fit may also reduce parcel volume and delivery charges.
Using less filling can support a more eco friendly packing process. Corrugated cardboard can also enter normal cardboard recycling after use.
Twin flutes improve compression and puncture resistance, providing additional rigidity for stacking, heavier loads and demanding delivery routes.
Measure the internal length, width and height of your product. Select a footprint that fits its longest and widest points.
Choose the lowest score line that leaves enough room for any cushioning. Add paper void fill, bubble wrap or another suitable material if the item could move during delivery.
Seal the base before packing. After adjusting the height, close the top and use strong packing tape across the centre and outer edges.
Choose the shallowest suitable score while still leaving enough room to protect the contents. This helps reduce unnecessary empty space and can help control volumetric parcel size.
Fragile goods should still be properly cushioned. Adjusting the box height reduces excess space, but it does not remove the need for protective packaging where required.
For pallet stacking, keeping a consistent footprint can make loads easier to organise. Cardboard layer pads can also be used between tiers where additional stability is needed.
The number and position of score lines varies between products. The examples below illustrate common multi-depth configurations. Always check the individual product information for the exact sizes and score lines available.
| Footprint (L × W mm) | Available depths (H mm) | Best for |
|---|---|---|
| 400 × 300 | 400 / 350 / 300 / 250 | Mixed components, tools, small appliances |
| 457 × 305 | 450 / 400 / 350 / 300 | Books in bulk, kitchenware, electronics |
| 500 × 400 | 500 / 450 / 400 / 350 | Fragile homeware with extra cushioning |
| 600 × 400 | 600 / 500 / 400 | Multi-item picks, export packing, pallet builds |
Lightweight and cost-effective cardboard boxes for lighter products, everyday parcels and less demanding delivery routes.
Fixed-height heavy-duty packaging offering additional rigidity for heavier, fragile or stacked shipments.
Adjustable heights combine double wall strength with the flexibility to reduce empty space and use fewer individual carton sizes.
Twin-flute board provides durability while multi-depth scoring gives you the flexibility to adjust carton height around different products.
Reducing unnecessary empty space can limit movement inside the carton and reduce the amount of void fill required.
One adjustable carton can cover several packing heights, helping simplify purchasing, stock management and warehouse storage.
Using fewer carton sizes and creating closer-fitting parcels can help reduce packaging usage, storage requirements and unnecessary parcel volume.
Variable product heights — use the same length and width while selecting the score line that best suits the contents.
Mixed ecommerce orders — adjust the box around different combinations of products without keeping a fixed-height carton for every order.
Fragile products — select a depth that leaves enough room for suitable cushioning without creating excessive empty space.
Warehouse & distribution — fewer carton sizes can simplify packing stations and stock management.

No. The score lines help you create a clean fold. The twin-flute board continues to support the contents when you fold it correctly.
They work well for ecommerce orders with different product combinations, tools, components, small appliances, fragile homeware, multi-item orders and warehouse picking and packing.
Fragile products may still need cushioning. Use enough material to prevent movement without leaving unnecessary empty space.
