Cardboard Pallets
Also known as paper or corrugated pallets, these are made from recycled cardboard, providing a sustainable, low-cost solution for light loads (up to 1,000 kg). They’re biodegradable and exempt from ISPM 15 rules, but they’re vulnerable to water and not ideal for repeated use.
Benefits: Reduce environmental footprint and shipping fees due to their featherlight design.
Applications: Common in retail displays, export of lightweight goods like electronics, or one-way shipments in e-commerce.
7 Essential Pallet Configurations
Beyond materials, pallets vary in design and structure, influencing how they’re handled, stacked, and loaded. Configurations like deck boards, stringers, and blocks determine accessibility and stability.
#1 – Roto-Molded Pallets
Produced through rotational molding—a process that creates a seamless, one-piece structure—roto-molded pallets are cost-effective and available in standard dimensions. Reinforcing them with steel inserts boosts load capacity up to 1,500 kg dynamic. Their smooth surfaces prevent bacterial buildup, making cleaning effortless.
Advantages: Lightweight, impact-resistant, and customizable for nesting when empty.
Drawbacks: Limited color options and potential for warping under prolonged sun exposure.
Applications: Widely used in pharmaceutical and food industries for sterile transport, such as moving medical supplies in hospitals.
#2 – Injection-Molded Pallets
These pallets are formed by injecting molten plastic into molds, resulting in uniform, flat designs in various colors and sizes. HDPE versions are corrosion-proof, recyclable, and withstand temperatures from -40°C to 60°C, with load capacities often reaching 2,000 kg.
Pros: High precision ensures consistent performance; easy to integrate with automated systems.
