Custom Corrugated Box Inserts & Dividers
SKU: BI-03
Custom corrugated box inserts are die-cut corrugated trays, partition grids, and internal dividers used to separate, cushion, and stabilize products inside shipping cartons, mailer boxes, gift boxes, and retail packaging.
Before production, buyers should confirm product size, product weight, outer box size, packing quantity per carton, cell size, flute direction, slot tolerance, surface sensitivity, drop test needs, and export packing method.
- Project-specific structure
- Material and artwork review
- Sample approval
- Quotation-based supply

Is This Direction Right for Your Project?
Good Candidates for Review
Products with defined support, retention, removal, outer-box fit and packing requirements.
Review Another Direction When Needed
Projects lacking a stable product reference, support plan, material route or representative approval sample.
Material, Performance and Claim Boundaries
No material, environmental, food-contact, barrier, load, adhesion or route performance is assumed from the product name alone. The selected construction, supplier evidence, sample, test scope and destination requirements must be confirmed for the project.
Artwork, Sampling and Production Approval
- Define the pack: Send product, size, weight, orientation, artwork, quantity, packing and destination.
- Confirm the direction: Review structure, materials, print, finish and evidence requirements.
- Approve files: Confirm dieline, artwork placement, copy, color and production notes.
- Approve the sample: Check fit, assembly, appearance, packing and the agreed test scope.
- Release production: Confirm quotation, approved references, QC points, packing and shipment.

Frequently Asked Questions
Is corrugated better than foam for heavy items?
Corrugated inserts are often a strong paper-based option for heavier products that need separation, compression resistance, flat-packed logistics, and carton stability.
How do I choose between E-flute, B-flute, C-flute, and BC-flute inserts?
E-flute is often used for lighter retail inserts and compact trays. B-flute is stronger for bottle dividers, jars, candles, and heavier carton protection.
What should be checked before approving a corrugated insert sample?
Before approving a sample, check cell size, slot width, slot depth, flute direction, product fit, top clearance, bottom clearance, product movement, surface scratching risk, and outer box fit.
Will corrugated board scratch my product?
Standard corrugated board may be too abrasive for glossy, painted, acrylic, coated, or highly sensitive surfaces.
Do corrugated dividers need top and bottom pads for glass bottles?
For glass bottles, jars, and candles, top and bottom pads may be recommended when vertical impact, carton stacking, or product movement is a concern.
Can corrugated inserts pass a drop test?
Corrugated inserts can support many transit protection goals, but drop test performance depends on product fragility, outer carton strength, insert structure, board grade, packing method, and test standard.
Do corrugated inserts need assembly?
Most corrugated inserts and dividers are supplied flat to reduce shipping and storage volume.
Can you make corrugated dividers for 6 or 12 bottles?
Yes. We can design interlocking corrugated dividers for 2, 4, 6, 12, or custom bottle and jar layouts based on product diameter, height, and outer carton size.
When should I choose EVA foam, molded pulp, or paperboard dividers instead?
EVA foam may be better for delicate, high-value, or presentation-focused products that need soft contact and shaped cavities. Molded pulp may be better for molded paper-based protection. Paperboard dividers may be better for lighter retail products that do not need corrugated cushioning.
Can corrugated inserts be supplied together with outer boxes?
Yes. HS PACKFACTORY can coordinate corrugated inserts with corrugated boxes, mailer boxes, folding cartons, rigid boxes, labels, instruction manuals, and complete packaging sets.
How should corrugated inserts be packed for export or pallet shipping?
Corrugated inserts can be supplied flat-packed, pre-slotted, bundled, carton-packed, installed into boxes, or palletized depending on the buyer’s receiving workflow.
What information do you need for a quote?
Please send product size, product weight, outer box size, packing quantity per carton, protection goals, material preference, artwork file, order quantity, packing method, and delivery country.
