Packaging Corner: Pallet additives and special formulations help keep food safer

Just as consumers have become more aware of the ingredients in their food, so have the operations that handle those products as they travel from farm to fork—specifically with regard to the formulations of the pallets upon which edibles are transported, says Curt Most, senior product manager for ORBIS Corp.’s reusable plastic pallet lines.

“Food processors have become increasingly concerned about eliminating possible sources of contamination in food, including from pallets,” Most explains. “So, in addition to offering plastic pallets that are engineered to be easily cleaned and not harbor pests or pathogens, we’ve developed a variety of special resin formulations and additives to meet those needs.”

Some processors have incorporated metal detectors and/or X-ray machines into their handling lines as a means to detect foreign objects. Every pallet load of consumables—particularly produce and other perishables—passes through one of these machines to verify that they are contaminant free.

“Small pieces of debris can be hard to detect with these systems,” Most points out. “That’s why we offer various detectable additive options to our 40 x 48-inch GMA pallets made of 100% virgin resin.”

Metal and X-ray detectors easily identify these types of proprietary detectable additives, making it easier to ensure the safety of the product that’s being carried. Should a piece of an ORBIS pallet happen to wind up in the load, either system triggers an alert and stops the line.

Although the plastic pallets are inherently durable, those moved from ambient locations into and out of refrigerated or freezer environments can be more susceptible to damage from impacts. “To compensate for the temperature fluctuations that can affect the resin—potentially making it more brittle—we also offer a special formulation for those applications,” adds Most.

Companies considering a special formulation or additive for their plastic pallets only have to order a minimum of 250 pieces. Most says that the company works closely with customers to make sure that both the correct pallet and the proper handling procedures are put in place.

“We want to be sure that the performance of the material meets their needs long-term, because the pallets are engineered to last long-term,” he adds.
