NWPCA Updates PDS Users Guide, One-Stop Shop for Pallet Design
Available in English, Spanish and French

Today, the National Wooden Pallet & Container Association (NWPCA) releases Pallet Design System™ (PDS) Version 6.4. The main feature in this release is a translation of the PDS User’s Guide in Spanish and French. The addition of these two languages in the User’s Guide complements the existing software interface already being used in eight languages in more than 30 countries, and further expands our global accessibility in pallet design.

The User’s Guide is considered the authoritative book on pallet design with its glossary, tables and other terminology. There is a wealth of information in the 300+ page Guide with numerous solutions to the most common questions in pallet design.

“From fasteners to lumber, pallet designers learn more about how different aspects of these components can impact overall pallet performance,” said Brad Gething, PhD, Vice President, Science & Technology. “The national and international wood species tables and fastener characteristics are invaluable tools in the User’s Guide and referenced quite frequently, whether or not you’re using PDS for pallet design.” The Guide was carefully reviewed and updated during the translation phase for a more intuitive, user-friendly product.

“The User’s Guide in PDS does such a great job of explaining how to use a particular feature, so there is zero reliance on technical support,” said John Dye, Scott Pallets, United Kingdom. “We use it to train new PDS users so they can better understand the interaction of all the materials used in pallet design with pallet performance.”

Illustrations and figures were all revamped and modernized as part of this new release, led by George Scharps, PDS Associate Engineer and John McLeod, PDS Advisor to the President.

Special thanks to the Softwood Export Council for their partnership and support in this project. With the expanded languages, new international markets can now benefit from the User’s Guide as well.

NWPCA Releases Pallet Design System™ 6.2

WHAT’S NEW IN PDS 6.2

PDS 6.2 makes it possible to design overlap-base block pallets with recessed bottom decks. It also contains an important extension to our unit load for boxes analysis capabilities.

Improvements and new features included in PDS 6.2 are:

• Filler boards and trenched stringer boards can be added to overlap base block pallets.
• Interlock stacked boxes can be analyzed for unit loads.
• Forklifting from the end of stringer pallets can be analyzed when there is no stringer between the fork tines.
• Improved properties for air dried softwood pallets that are assembled green and dried prior to use.
• The PDS installer is now available in many languages, in addition to English: German, Italian, French, Dutch, Spanish, Portuguese

PDS 6.2 can draw and analyze a new family of overlap-base block pallets having uninterrupted, flat bottom decks. Pallets with flush bottom decks are advantageous when stacking unit loads such as drums. The deck engages over more of the top surface of the bottom unit load, providing better support to the upper unit loads and reducing the risk of damage to the cargo on the bottom pallet. Overlap base pallets can be made stronger and more durable than perimeter base pallets due to the better connections in the bottom deck. Now you can have the best of both worlds – a strong overlap-base pallet which has a flat and continuous bottom deck. This is essential for designing CP-9 pallets which are popular in the chemical industry. The gaps that would normally be there between the deckboards are either filled with nailed-on filler boards or the deckboards are recessed into a thicker stringer board that has been trenched (dadoed) to accept them.

PDS 6.2 allows interlock stacked box unit loads to be analyzed. Interlock stacking tends to shift more loads away from the pallet while greatly reducing the crushing resistance of the boxes. While not lending itself towards optimization of corrugated boxes, it is used to improve the stability of unit loads, particularly, when stretch wrap or other stabilizers have not been applied.

Research & Abstract by Page Clayton, Virginia Tech, CPULD
Fall 2018

This study aims to investigate pallet deflection as a result of different sized packages in a column stacking pattern and the presence of headspace in the box.

Pallets are the foundation of unit loads and supply chains. They provide a way to store and transport products in an efficient manner. Currently, however, the use of “component based” designs for unit loads doesn’t consider the interaction between unit load components or how this interaction effects the overall structural integrity of the unit load.

Component based unit load designs also result in the excessive use of raw materials which reduces the sustainability of unit loads, drives costs up, and creates issues for people in the supply chain.

The objective of this study was to investigate the interactions between the unit load components, box size and package head space, especially focusing on the deflection of the pallet as a function of pallet stiffness across multiple common pallet support conditions.

This study aimed to investigate pallet deflection as a result of different sized packages in a column stacking pattern and the presence of headspace in the box. The effect of each of these components on deflection is known as load bridging, in which a redistribution of stress occurs depending on the loads’ characteristics within the unit load.

Results showed that, in a column stacked arrangement, smaller boxes caused greater deflection than larger boxes (up to 53 % higher). Data analysis identified that a change in box size causes a decrease in the deflection of a pallet; smaller boxes, with the same load, transfer less pressure to the supports (31% less) and cause more deflection (53% more) than large boxes, especially on lower stiffness pallets. The presence, or lack, of headspace in a box didn’t have any significant impact on deflection.

This study confirmed that supported pallet components do, in fact, carry more of the weight of the load and that the boxes’ sizes do affect deflection. The experiments from this study confirm that the compressive pressure across the top of the pallet surface redistributes itself towards the supports of pallets when the sizes of the corrugated boxes increase. As more of the compressive forces redistribute across the top of the pallet to the supports, the deflection along the free span decreases.

These quantitative results can help to further understand the load bridging effect and allow us to make adjustments based on the current safety factors. Therefore, to increase the sustainability of pallets and to conserve resources, it is recommended that pallets are always designed with product packaging designs in mind.

Research funded by the Pallet Foundation of the NWPCA and by the U.S. Forest Service. Paper submitted to the IAPRI Peer Review Stream.

March 12, 2020: Last night, the Environmental Protection Agency’s Administrator, Andrew Wheeler, signed into regulation language that opens the path for wood pallet residuals to be sold as wood pellet fuel. NWPCA’s Vice President of Advocacy and External Affairs Patrick Atagi said, “NWPCA members were able to be proactive and change existing federal regulation that had previously prevented recycled wood pallets from being used in pellet fuel.” Atagi continued, “I’m very proud of NWPCA members, the pallet industry, and EPA to make this change – it shows working-together-works! A special shout-out to BDL Supply, CHEP/Brambles, Hay Creek Pallet Co., Industrial Pallets, Northland Pallet, Vecoplan Midwest and WestWind Logistics for their time, energy and tremendous support.”

On March 16, 2015, EPA issued a final rule revising the Standards of Performance for New Residential Wood Heaters. 80 Fed. Reg. 13,671 (Mar. 16, 2015). In that rule, EPA promulgated regulations governing requirements for pellet fuel. EPA also listed a variety of prohibited fuel sources. One such category of sources was “Railroad ties, pressure-treated wood or pallets.” The language inadvertently, but effectively, prevented wood pallets from being certified as wood pellet fuel. The pallet industry prides itself on its environmental footprint; including a 95% recover, recycle rate that leads the landfill avoidance rate of all competing packaging materials.

With the passage of this revised regulation, the wooden pallet industry can maintain and grow its recycling rate even further. This is a fantastic win for the environment, the industry, and NWPCA members – job well done!
