Description
Products shifting inside a carton can arrive scratched, broken or poorly presented. Loose cosmetics bottles may knock against each other, candle jars can strike the box walls, and multiple products can become disorganised during courier handling. A correctly designed cardboard insert keeps each item in its intended position and makes the finished package easier to pack.
Product Boxes UK manufactures custom die cut cardboard inserts UK businesses can use for e-commerce orders, retail packaging, gift sets and wholesale shipments. Choose from fitted trays, internal dividers, layered platforms and folded supports designed around your product dimensions.
Our Custom Inserts, Tissue & Tape range brings together practical packaging components for businesses that want a coordinated packing solution. From a single-product support to a multi-compartment insert, each design can be developed to suit the outer box, the contents and your packing process.
Custom Insert Styles and Precision Dieline Design
The insert should be designed alongside the outer carton. Its dimensions, folds and cut-outs need to work with the internal measurements of the box and the shape of the products being packed.
We offer several structural approaches for different packaging requirements:
| Insert style | Construction | Typical applications |
|---|---|---|
| Die-cut tray inserts | Shaped board with product-specific recesses | Cosmetics, candles, bottles and accessories |
| Cross-partition dividers | Interlocking cardboard sections forming separate compartments | Multiple jars, glass products and multi-packs |
| Fold-over safety platforms | Layered or folded board providing additional support | Fragile products and items requiring base separation |
| Custom platform inserts | Die-cut supports with raised or recessed sections | Gift sets, electronics and promotional kits |
| Multi-level inserts | Separate board layers for organised product placement | Bundles, presentation packs and assorted products |
Bespoke die-cut cardboard inserts for boxes can be produced around product length, width, height, weight and contact points. This is particularly useful when a standard divider leaves too much space or fails to support an irregularly shaped item.
CAD-based dieline planning helps establish where the board will be cut, folded and assembled. The insert can include finger slots for easier product removal, locking tabs to hold compartments together and folded edges for additional rigidity.
For suitable products, a fitted fibreboard insert can replace loose plastic filler or some foam components. This depends on the level of cushioning required, the product’s weight and the intended delivery conditions. The objective is a secure arrangement that limits movement without making packing unnecessarily complicated.
Select the Right Cardboard Grade for Your Products
Board choice affects the insert’s stiffness, folding performance, thickness and ability to support the contents. Lightweight accessories need a different construction from glass candle jars or multiple heavy products packed together.
| Board stock | Typical construction | Load suitability | Primary applications | Environmental profile |
|---|---|---|---|---|
| Folding cardstock | Around 350 GSM | Lightweight products and smaller compartments | Cosmetics, samples and accessories | Fibre-based; suitability for recycling depends on the finished material |
| E-flute corrugated | Approximately 1.5–2 mm flute profile | Light to medium-duty support, depending on design | Candles, electronics and retail packs | Paper-based construction; coatings and adhesives can affect recovery |
| B-flute corrugated | Approximately 2.5–3.5 mm flute profile | More substantial support for suitable heavier products | Shipping dividers, multi-packs and larger items | Fibre-based; confirm the complete packaging’s recycling route |
| Layered corrugated board | Multiple board layers or reinforced folds | Applications requiring additional structural support | Fragile products and larger product combinations | Material use and recovery depend on the final construction |
Load suitability is indicative, not a guaranteed weight rating. Actual capacity depends on the insert geometry, board grade, outer carton, product contact points and handling conditions. Test the finished pack before using it for heavy or fragile shipments.
Inserts for Cosmetics, Candles and Electronics
Eco-friendly cardboard inserts for cosmetics and candles offer a paper-based way to organise compatible products inside retail and delivery packaging.
For skincare and cosmetics, cut-outs can separate bottles, jars, palettes and sample containers. For candles, an appropriately designed tray can support the glass base and help prevent the vessel moving inside its carton. Electronics packaging may use compartments for devices, chargers, cables and accessories, with additional cushioning where the product requires it.
The insert must match the product’s shape and weight. Heavy glassware and sensitive electronics should not rely on a thin cardstock tray alone. A stronger corrugated construction or an additional protective solution may be necessary.
Custom Printing, Colours and Finishing Options
Cardboard inserts do not have to remain plain. Printing the visible insert surfaces can extend your brand identity into the packaging interior, particularly for premium retail products, gift sets and direct-to-consumer deliveries.
Available customisation options include:
- White board: Provides a clean surface for bright colours, product information and detailed brand artwork.
- Natural Kraft board: Creates a brown, understated appearance suited to minimalist and natural-style packaging.
- CMYK interior printing: Adds full-colour graphics, product identification or brand messages to visible insert faces.
- Pantone colour matching: Helps maintain consistency with your established brand palette.
- One-colour printing: A straightforward option for logos and simple designs.
- Die-cut finger slots: Makes products easier to lift from fitted compartments.
- Folded and layered supports: Adds structure without requiring a separate plastic tray.
Soy-based inks can be considered for suitable print specifications, subject to availability and confirmation from the production supplier. Ink selection, coatings and adhesives should be assessed as part of the complete packaging if recyclability is important to your business.
A printed insert can also carry product instructions, promotional messages or a welcome note. The artwork needs to be positioned around the folds and cut-outs so important text is not lost during assembly.
Complete Your Packaging with Compatible Products
An insert works best when its dimensions match the carton holding it. Our custom mailer boxes can be specified alongside internal trays and dividers for e-commerce orders. For products requiring more substantial cushioning, explore our branded protective packaging range.
Combining the outer box and insert in one packaging specification helps avoid fit problems and gives your fulfilment team a consistent packing arrangement.

Custom corrugated packaging inserts wholesale UK orders can be planned around individual product requirements or standardised across several compatible box sizes.
For projects requiring custom packaging insert dielines, low MOQ options can be discussed according to the board grade, cutting requirements and design complexity.
