It can under some conditions. Fibre source, recycled content, additives, coatings, storage and absorbed environmental odours may matter. Evaluate the exact board with the intended food and package structure.

Potential pathways include set-off when blanks are stacked, gas-phase transfer and migration through the substrate. Outside printing is not automatically irrelevant to the completed package.

No. Odour is a sensory property, while migration concerns substance transfer. A low-odour ink may still require migration assessment, and a controlled-migration system may still need sensory evaluation.

Incomplete drying or curing may leave volatile or reactive components and can affect set-off and migration. Confirm the specified ink system, cure conditions, hold time and verification method.

Potentially, depending on adhesive chemistry, coat amount, cure, residuals, contact geometry and barrier layers. Request exact product information rather than a generic food-grade statement.

Sensitivity varies with aroma, fat and moisture content, surface area, temperature and storage time. The food producer should define the worst intended product and use condition for assessment.

No. Barrier performance is substance-, material-, thickness-, temperature- and time-dependent and may be interrupted at seams, cuts or closures. Verify the complete structure.

Yes. Paper-based materials and finished packs can be exposed to fuels, chemicals, fragranced products, dampness or contaminated pallets. Storage and transport segregation are part of risk control.

Request board, ink, coating and adhesive identification; declarations or statements for the target market; composition or migration information where applicable; curing guidance; and traceable lot documentation.

Use production-representative printed, converted and packed samples with the intended food or justified simulant. Assess migration and sensory effects under relevant time, temperature and storage conditions.
