Plastic pallets are becoming a common sight these days. The reasons are quite clear - plastic pallets have many advantages compared to their wood counterparts.
For starters, plastic pallets are easy to sanitize because they can be washed and disinfected between shipments. In foodservice logistics, this feature can help to reduce cross contamination and can also prevent the spread of foodborne illness because they don't absorb pathogens.
Wood pallets, on the other hand, require fumigation or heat treatments to be sanitized. These processes can cause pallets to become subject to mold as well.
Wooden pallets also have nails which can become rusty, creating a hazard for shipments. Because plastic pallets are injection molded, they won't splinter or risk puncturing shipments.
