Why plastic wins where it matters most — food, pharma, clean-room and export. This guide compares plastic and wood roll pallets on hygiene, HACCP, ISPM-15 and contamination risk, not just price.
For ordinary loads the wood-versus-plastic debate is mostly about cost and life. For rolls and reels destined for food, pharmaceutical, hygiene or export use, it is about compliance and contamination — and there plastic is not a preference, it is a requirement. This guide focuses on the hygiene and regulatory case; for the cost-over-life view see the life-cycle comparison.
The problem with wood in roll handling
Wood is porous, absorbs moisture and harbours what regulators care about: bacteria, mould and pests. In roll handling it has three specific failings. It splinters, and splinters end up in film, paper and the wound material, damaging the roll and the converted product. It absorbs liquids and cleaning agents, so it can never be reliably sanitised. And it degrades with every wash, which means it cannot survive the repeated cleaning that hygienic environments demand. A cracked or damp wooden cradle is a contamination event waiting to happen.
HACCP, food and pharma
HACCP and GMP-style audits favour closed, washable, non-absorbent surfaces that can be cleaned and verified. A hygienic H1-type plastic pallet has exactly that: a sealed HDPE surface with no cavities to trap residue, washable at temperature, and free of nails, splinters and moisture. Wooden pallets routinely fail food and pharma audits for the opposite reasons. If your rolls touch food packaging, labels, pharmaceutical foil or any product entering a controlled environment, the pallet itself is part of the hygiene chain — and it has to be plastic.
ISPM-15 and export
Wood packaging crossing borders must be heat-treated and stamped under ISPM-15 to prevent pest transfer. That adds cost, paperwork and the risk of a shipment being held or rejected at the border if treatment is missing or marks are unclear. Plastic is exempt from ISPM-15 entirely — it is not a phytosanitary risk, needs no treatment, no stamp and no certificate. For exporters of rolls and reels, plastic removes a whole category of customs friction.
Contamination risk compared
| Risk | Wood | Plastic (HDPE) |
|---|---|---|
| Splinters into the roll | High | None |
| Absorbs moisture / liquids | Yes | No |
| Harbours bacteria / mould | Yes | No (washable) |
| Survives repeated washing | No | Yes |
| Pests / ISPM-15 for export | Treatment required | Exempt |
| Nails / loose fasteners | Yes | None |
Durability is a hygiene factor too
Hygiene is not a one-time property — it has to hold across hundreds of cycles. Wooden cradles crack, swell and shed within a few uses; once damaged they can no longer be cleaned to standard. A reusable plastic cradle keeps its closed, washable surface for years, so the hygiene guarantee is the same on cycle one and cycle five hundred. This is why hygiene-critical operations standardise on plastic even before the cost argument.
When is wood acceptable?
Rarely, and only outside hygiene and export contexts: a one-way domestic shipment of a non-sensitive roll, where the pallet is discarded and there is no audit, no export and no contact with food, pharma or clean material. In almost every other roll-handling case, plastic is the lower-risk and lower-total-cost choice.

Frequently asked questions
Q: Why are wooden pallets not allowed in food and pharma? A: Wood is porous and absorbent, so it harbours bacteria and mould and cannot be reliably sanitised; it also splinters and carries nails. HACCP and GMP-style audits require closed, washable, non-absorbent surfaces, which is why hygienic H1-type plastic pallets are used instead.
Q: Do plastic pallets need ISPM-15 treatment for export? A: No. ISPM-15 applies only to wood packaging, which must be heat-treated and stamped. Plastic pallets are exempt — no treatment, stamp or certificate is required — which removes a common cause of customs delays for exporters.
Q: Can wooden roll cradles be cleaned and reused? A: Not to a hygiene standard. Wood absorbs liquids and cleaning agents and degrades with each wash, so it cannot be reliably sanitised or survive repeated cleaning. Plastic cradles keep a closed, washable surface across hundreds of cycles.
Q: Is plastic only better for hygiene, or also for cost? A: Both. The hygiene and export advantages are decisive in food, pharma and cross-border use; over a multi-year life plastic also costs less than repeatedly replacing wood. See the life-cycle comparison for the cost detail.
