Timber has traditionally been the material of choice for pallets, but that could be about to change as more users shift to plastic pallets. When was the last time you compared the two alternatives?
Let’s take a look.
1. Covid/Brexit Threaten Timber Pallet Availability & Price
In February 2021, Global Cold Chain News reported that the combination of the Covid-19 pandemic and Brexit are affecting both the availability and cost of timber pallets. Referring to findings by independent market report company Afry they told of how the index price of homegrown (UK) pallet timber rose by 13.2% in the last quarter of 2020 and still maintained a 4.4% increase during the first month of this year.
This double-whammy to the timber pallets industry could result in users not only seeing plastic pallets as a more cost-effective alternative but even being forced into buying them to ensure continuity of supply.
But while price alone is rarely a deciding factor in making such a monumental change, there are other reasons why plastic pallets make more sense.
2. ISPM15 Regulations Up the Ante for Solid Wood Packaging
International Standards for Phytosanitary Measures – the protection of humans, animals and plants from contaminates, pests or diseases – apply to all packaging products made from solid timber thicker than 6mm (plywood and other processed wood products are exempt).
If you’re importing solid wood packaging (either as a product for resale or as part of your products’ transit packaging) into the UK or exporting to certain countries (check here for a list of relevant countries) it will need to meet ISPM15 standards.
If you repair, remanufacture or modify ISPM15-compliant packaging, it will need to be re-treated and restamped to comply before it can be reused. This will undoubtedly add unwanted costs and delays, as wooden pallets frequently suffer damage or deterioration in transit and storage.
3. Plastic Pallets Are More Hygienic
While ISPM15 standards are designed to reduce the human and environmental health risks of wooden pallets, timber essentially remains a porous material. Also, the joints between the various components of a pallet all act as perfect traps for contamination.
Plastic pallets are conventionally a single-piece polypropylene moulding that can be easily pressure washed or sanitised if any hazardous spillages or contact occurs.
4. Plastic Pallets Are More Durable
Pallets come in for a lot of harsh treatment during their life cycle: knocks and twists during handling, dynamic loads during shipping, static loads during storage, and constant changes of temperature and humidity, particularly if used for outside storage.
All these pressures can take a toll on the pallet’s construction. Timber pallets are only held together with relatively thin nails and one heavy impact or frequent, smaller blows can weaken or break that bond. Knots and faults in the timber itself can also create weak points that give way under sudden or prolonged pressure.
Polypropylene offers excellent resistance to mechanical, loading and climatic stress, and plastic pallets will continue to perform up to their approved dynamic and static load rating for their entire life cycle, in all weathers.
The injection moulding process creates a uniform molecular structure within a plastic pallet, and potential weak points are reinforced during the design stage.
5. Plastic Pallets Are Recyclable
When a wooden pallet reaches the end of its useful life, the options are limited. Any timber still in reasonable condition can be used to remanufacture pallets or other timber packaging, but if it has splintered or deteriorated it will probably be turned into biomass fuel or sent to landfill.
On the other hand, polypropylene pallets can be easily ground down and reformed into granules. The raw material is then used to manufacture new plastic products, and this recycling process can happen time and again.
6. Plastic Pallets Are Lighter (And Don’t Gain Weight)
The unladen weight of a pallet varies depending on its construction – wooden pallets typically weigh between 15 and 70 kg. Compare this with plastic pallets which can take similar load weights, but come in at between 4 and 24 kg.
Another factor to consider is that a wooden pallet, when wet, is considerably heavier than when it is dry. Plastic pallets maintain a constant weight, even if they are standing in water.
The added weight of wooden pallets has two potential consequences: additional shipping costs due to higher total load weights, and a higher risk of musculoskeletal complications or injury if pallets are being handled manually.
7. Plastic Pallets Are Safer
Maybe the best way to illustrate this is by looking at the ways in which wooden pallets are unsafe.
• We have just mentioned how manual handling of heavy wooden pallets can potentially cause musculoskeletal complications or injury. This threat is increased if the pallets are wet, or if they are handled over a protracted period.
• The softwoods used for pallets have a high tendency to split if damaged, creating jagged edges and splinters that can catch on clothing or lacerate skin.
• Damaged wooden pallets may collapse, creating unstable loads that can fall with severe consequences.
