An insert should hold the product, organise the contents and work with the packing process. Choose the structure around the actual product rather than the material name alone.
Paperboard: folded and compact
Cut and folded paperboard can locate products and coordinate with printed packaging. Check support points, locking tabs and assembly. An opening that fits the product does not by itself show where its weight is supported.
Corrugated board: partitions and supports
Corrugated inserts can form dividers, cradles and layered supports. Confirm the board construction and geometry together. Review exposed flute edges when the insert is part of the gift presentation.
Molded fibre: shaped around the product
Formed trays need discussion of tooling, geometry and sample revisions. Ask about achievable details, surface finish, packing volume and nesting. Confirm that the proposed quantity justifies the development cost.
Test the fit and packing work
Use representative finished products with their caps, labels and accessories. Check insertion, support, clearance and removal. Have the packing team assemble several samples and note extra handling or adhesive.
Review the complete shipping pack
Assess the product, insert, box, cushioning and outer carton together. Agree suitable tests for the delivery conditions. A neat fit or attractive sample photo alone does not establish transit protection.
Prepare an insert brief
Send product dimensions, weight, photos, box internal dimensions and quantity. Explain vulnerable surfaces, presentation priorities and packing sequence. Ask for sample, tooling and courier charges before approving development.
