Before choosing solid board or corrugated cardboard dividers, establish whether they only separate products or also help support a load. Function comes before material selection. A divider that performs well against lateral contact may be unsuitable if the top of the pack transfers an unplanned load into its walls.<\/p>\n

Trace the load path through the closed pack<\/h2>\n

Draw a section showing the base, product, divider, any intermediate pad and the top of the box. Identify which surfaces touch when the pack receives a vertical force. Does it pass through the product bodies, their closures, the partitions or another structure? This drawing exposes unintended contacts. A pump or fragile cap should not become a support simply because it projects slightly above neighbouring parts.<\/p>\n

Repeat the review for height variations between product references. A shorter product may leave the lid resting on the divider, changing the assembly’s behaviour. Request an explicit definition of any load-bearing function rather than a general assurance that the board is strong. The supplier needs to understand the complete arrangement and the conditions in which that function will be used.<\/p>\n

Compare complete designs rather than material labels<\/h2>\n

Solid board and corrugated board need not occupy the same space within a cell. Changing material can therefore alter clear openings, overall divider size and box dimensions. A comparison based on an unchanged drawing may unfairly disadvantage one option or prevent some products from fitting at all. Ask for designs developed around the same functional requirement.<\/p>\n

Estic-Maillot’s partition information<\/a> discusses corrugated dividers in applications where the divider is expected to carry load. This helps frame the study; it does not establish an allowable load for every corrugated grade. Compare the proposed material, geometry, joints and operating conditions together. The words solid board and corrugated board describe families, not complete specifications.<\/p>\n

Distinguish hand stiffness from tested performance<\/h2>\n

A strip that feels firm between the fingers may behave differently after slotting and assembly. The height of its walls, connections and supporting surfaces affect the structure. Ask which tests characterise the board and which validate the complete pack. The first provides information about a component; the second examines the interaction between components and the product.<\/p>\n

FEFCO lists separate tests for board and for corrugated packaging<\/a>. This distinction is useful when reviewing supplier documents. A result obtained from a material specimen should not be converted directly into the carrying capacity of an assembled divider. Keep the measuring conditions and the scope of the conclusion visible in the comparison.<\/p>\n

Review product surfaces as well as support<\/h2>\n

The choice is not solely about vertical forces. Products may have decoration, coatings or a critical surface finish. Examine contact with the board face and with cut edges. Include any cleanliness requirements associated with the manufacturing process. Specify the expected outcome without assuming that a particular board family automatically satisfies every surface requirement.<\/p>\n

In a hypothetical comparison, both proposals pass a fitting check. One reduces occupied space and improves access; the other has been designed around an upper support function. Which is preferable depends on the actual need. If no load should pass through the divider, strengthening that function may add little value. If support is essential, a space saving does not justify removing it.<\/p>\n

Test the representative assembly<\/h2>\n

Prepare trials with production-representative products, boxes and accessories. Define the required condition after the agreed journey: no damaging contact, closure maintained, functional products and controlled internal arrangement. Where the pack will be stacked, include the relevant storage duration and environmental conditions in the programme agreed with the laboratory.<\/p>\n

Keep detailed observations instead of recording only pass or fail. Some deformation may be part of a validated protective function. Conversely, slight movement can be unacceptable if it brings a fragile feature into contact. Relate the criterion to the product and its intended use. A photograph of the outside of the box cannot explain all of these interactions.<\/p>\n

Include the effects on packing and purchasing<\/h2>\n

Check how each option is supplied, stored, opened and inserted. Differences in thickness or opening behaviour can affect a manual station or an automated line. Observe the actual work rather than assuming that the cheaper component also produces the cheaper packing operation. Any claimed improvement in labour or output should be measured within a defined comparison.<\/p>\n

Ask the quotation to identify the proposed grade and approved design. Record whether a material change would require another fitting or performance review. This matters when purchasing teams seek an alternative supply: matching the nominal cell dimensions does not necessarily reproduce the original functional assembly.<\/p>\n

Use a consistent decision checklist<\/h2>\n
