Folded support with defined tabs
Platforms, bridges, collars, and compartments can be cut and folded from board. Useful when presentation, efficient flat supply, and a fiber-led material system matter.
Product-fit trays and cavities
Custom packaging inserts engineered for fit, protection, and removal.
Select material only after the real product, retention points, opening sequence, outer box, separation goal, and transit risks are defined.

Choose by load path, cavity, and end of use.
Material names do not predict performance on their own. Density, thickness, grade, surface, forming method, adhesives, and the outer box are part of the specification.

Shaped fiber with draft and radius
Formed pulp can cradle three-dimensional products, but draft angles, radii, wall thickness, surface texture, tooling, and available grades constrain fine geometry.
Precise visual cavities
EVA can provide crisp cut edges, layered depths, and controlled presentation. Density, color, odor, surface contact, adhesive, and disposal route require project review.
Resilient cushioning
EPE can be considered where light weight, recovery, and shock cushioning matter. Thickness, density, lamination, cut quality, appearance, and specialist recovery options vary.
Presentation over a structural core
Fabric can wrap paperboard or foam for a finished interior. Seams, edge turns, fraying, color, adhesive, product contact, and component separation need explicit approval.
Material availability: density, color, fiber grade, fabric, coating, and documented content are confirmed for the quoted project. A reference photo is not a material specification.
Compare paperboard, molded pulp, EVA, and EPE insert tradeoffs before selecting the sample route.
Product data package
Design from the controlled product envelope.
A nominal size is rarely enough. The insert must account for production variation, mass, vulnerable surfaces, accessories, orientation, and how the user removes each item.
Scroll horizontally to view all columns →
| Product input | What to provide | Insert consequence |
|---|---|---|
| Geometry | Production-equivalent samples or controlled 2D/3D data with maximum dimensions and tolerances. | Sets cavity envelope, retention datums, wall thickness, cut paths, and surrounding clearance. |
| Mass | Actual packed weight, center of gravity, concentrated loads, and parts that can shift. | Changes support area, material density, base thickness, bridges, and outer-box loading. |
| Sensitive zones | Fragile projections, pumps, lenses, screens, seals, decorated surfaces, and no-contact areas. | Defines where the insert may restrain, where it must clear, and how pressure is redirected. |
| Presentation | Opening direction, product angle, visible faces, accessory order, documentation, and photography needs. | Sets cavity orientation, reveal height, layering, finger access, and removal sequence. |
| Pack-out | Manual or line packing, product insertion direction, protective bags, labels, and inspection steps. | Changes cavity access, flex points, assembly order, loose-part control, and line ergonomics. |
| Outer pack | Finished internal box dimensions, board structure, closure, master carton, and delivery route. | Controls the insert boundary, compression transfer, movement, and available protective depth. |
Cavity and removal
Retain the product without trapping the user.
A cavity should locate the product at controlled datums and resist movement in the expected directions. It should not pinch decorative surfaces, load fragile projections, or require unsafe force to remove the item.
- Define retention points on robust surfaces and clear fragile or cosmetic areas
- Add finger notches, lift ribbons, flexible tabs, or access wells around real hand movement
- Protect cables, leaflets, tools, and loose accessories from migrating under the main product
- Review insertion and removal with the product bag, label, cap, and final decoration in place

Separation and recycling brief
Make the material claim after the disposal path is known.
An insert is not automatically recyclable because it looks like paper or carries a familiar polymer name. Coatings, adhesive, fabric, labels, contamination, local collection, and the user's ability to separate components affect the outcome.
- Prefer one compatible material family where product protection allows
- Minimize permanent adhesive between unlike components and make removal understandable
- Document coatings, films, fabric wraps, labels, and hidden foam layers
- Check disposal wording and available recovery routes in the destination market
Drop and transit brief
Define the handling problem before choosing cushioning.
A parcel shipment, palletized retail delivery, and presentation kit carried by hand expose the insert to different loads. Formal testing is useful only when the method, conditioning, sample count, orientation, and acceptance criteria are agreed.
- Describe parcel or pallet route, overpack, stacking, orientation, and likely handling events
- Identify fragile thresholds, failure modes, no-contact zones, and acceptable cosmetic change
- State any required drop faces or heights, vibration, compression, temperature, or humidity conditions
- Separate design intent from a formal test result; testing scope and pass criteria require agreement
Tolerance stack
Fit is the sum of several moving dimensions.
A cavity can be correct in CAD and wrong in production if product, insert, box, and assembly tolerances are treated as one fixed number.
Design to controlled extremes
Use maximum and minimum production dimensions, not only one ideal sample. Include labels, coatings, bags, cables, and closure positions that alter the envelope.
Allow for the chosen conversion
Die cutting, creasing, pulp forming, foam cutting, laminating, wrapping, and adhesive each create different variation and edge behavior.
Measure the complete package
Outer-box internal size, insert position, glue, compression, hand assembly, and pack-out direction can shift the final cavity relative to the lid and product.
Approval rule: use production-equivalent products in a physical sample, record the approved support and removal behavior, and retain a signed reference for the production QC brief.
Sample to production
Approve fit before finish.
Development timing depends on product data, material availability, tooling, sample revisions, outer packaging, quantity, and any agreed evaluation method.
Product + transit brief
Confirm geometry, weight, fragile zones, orientation, outer box, route, material limits, and quantity.
Cavity concept
Set datums, retention, removal, material, wall or fold geometry, accessories, and pack-out sequence.
Fit + handling review
Pack production-equivalent products and check movement, contact, removal, outer-box closure, and agreed risks.
QC + assembly
Inspect material, dimensions, cavity, adhesion or folds, placement, count, fit sampling, and protective packing.
Insert QC brief
Inspect the function, not only the cut edge.
Visual quality matters, but a production insert also needs to locate, retain, release, and present the product consistently inside the approved outer package.
- Material grade, density or caliper, color, surface, odor requirement, and visible finish
- Overall dimensions, cavity position and depth, folds or seams, adhesive, and component alignment
- Fit across product tolerance, no-contact zones, retention, removal access, and accessory control
- Position inside the outer box, lid clearance, pack-out sequence, quantity, and transport protection
Packaging insert questions
Clarify fit, material, and verification early.
There is no universal best material. Die-cut paperboard supports folded platforms and material simplicity; molded pulp supports shaped fiber forms; EVA supports crisp presentation cavities; EPE supports resilient cushioning; and fabric-wrapped structures prioritize a finished interior. Product weight, fragility, cavity detail, removal, transit, appearance, separation, and available material grades determine the choice.
Provide a production-equivalent product or controlled drawing, maximum dimensions and tolerances, weight and center of gravity, fragile and no-contact areas, required orientation, accessories, outer-box dimensions, pack-out method, removal preference, quantity, and transit route.
Cavity tolerance is built from the product's dimensional range, insert material and conversion process, chosen retention points, surface sensitivity, outer-box variation, and assembly method. A physical sample with production-equivalent products is used to approve fit; a generic universal gap is not reliable.
Sometimes. Paperboard or molded pulp can replace foam when the geometry, weight, fragile zones, shock exposure, and presentation allow the fiber structure to control movement and load. A sample and the agreed transit brief should confirm performance before material substitution.
Recyclability depends on the exact material, coatings, adhesives, fabric, labels, contamination, component separation, and the collection system where the package is discarded. Paperboard and molded pulp may fit fiber streams when compatible; EVA, EPE, and mixed fabric-wrapped parts often require separate or specialist routes. Claims should be checked for the destination market.
The brief should identify product fragility, parcel or pallet route, expected orientation, drop faces or heights if specified, vibration, compression, temperature or humidity concerns, outer carton, and pass criteria. We design the insert around that brief, but any formal test method, laboratory, sample count, and acceptance result must be separately agreed.
Send product dimensions, tolerance and weight, photos or drawings, quantity, outer-box size and style, preferred material if any, presentation orientation, removal method, transit route, destination, target date, and any material or separation requirements. Physical product samples are useful before fit approval.
