Insulated Plastic Pallet Boxes

Double-wall insulated pallet boxes for food products

Double-wall insulated pallet boxes are designed for handling, storing and transporting food, liquids and other products that must be protected from temperature fluctuations. They are particularly well suited for fish, seafood, sauces, ice and many food-processing applications.

The four CPX models are rotationally molded in one piece. Their two polyethylene walls are filled with insulating polyurethane foam. This durable construction reduces heat transfer from the surrounding environment and helps preserve ice and maintain the temperature of the contents during handling or transportation.

An insulated pallet box does not generate cold and does not replace a refrigeration system. Its performance depends on the initial product temperature, amount of ice, ambient temperature, use of a lid, transportation time and frequency of opening.

The models shown are CFIA approved and meet FDA requirements for food applications. Their smooth, solid interior surfaces facilitate cleaning. The lid is sold separately.

Comparison of the four CPX models

All four models have the same 43 in × 48 in exterior footprint. Their height, interior volume, load capacity and permitted stacking height differ.

The model with the largest volume is not necessarily the best choice. The actual product weight, available height, handling method and frequency of movement must also be considered.

Why choose an insulated pallet box?

Reduced temperature fluctuations

The polyurethane foam between the two walls slows heat transfer. It helps preserve ice and limit temperature fluctuations during temporary storage, handling and transportation.

Temperature retention time cannot be determined from the box construction alone. It must be evaluated according to the product, load, lid, amount of ice and operating conditions.

Product protection and containment

The solid walls and bottom retain liquids, melted ice, sauces and wet products. This construction also provides better protection against dust and surrounding contaminants than a vented pallet box.

Each model includes a 2-inch drain that facilitates the removal of liquids, melted ice and wash water.

Easier cleaning

The smooth interior surfaces reduce the areas where residue can accumulate. The boxes can be steam-cleaned or pressure-washed according to the facility’s sanitation procedures.

The condition of the drain plug or valve and all sealing components should be checked before each food application.

Durable construction

One-piece rotational molding eliminates assembly joints in the main structure. The runners are molded directly into the box and allow it to be rotated during certain handling or cleaning operations.

Rotation must be performed with suitable equipment and a controlled method. The load, centre of gravity, available space and risk of the contents shifting must be evaluated before the operation.

How to choose the right model

Product volume and weight

Capacity in litres represents the available interior volume, while load capacity indicates the maximum displayed weight for the model. A box filled with a dense product may reach its load limit before reaching its full volume.

Calculate the weight of the product, ice and any added liquid. The weight of the pallet box must also be considered when selecting handling equipment.

Available height

All four models have a 43 in × 48 in exterior footprint, but their heights range from 28 to 47 inches. Check doorways, conveyors, cold-storage rooms, clearance beneath equipment and the interior height of trailers.

Height also affects manual access to the contents. A deeper pallet box may be less practical when employees must regularly reach the bottom.

Forklift and pallet-jack handling

The CPX318 provides two-way access for a forklift or pallet jack. The CPX327, CPX332 and CPX335 provide four-way forklift access and two-way pallet-jack access.

This difference must be considered based on aisle width, box orientation and the method used to load trucks or supply workstations.

Stacking

The CPX318, CPX332 and CPX335 can be stacked up to four high with their lids. The CPX327 can be stacked up to three high with its lid.

These limits should not be used alone to establish a stacking configuration. The weight of the contents, load distribution, floor stability, temperature and storage duration must also be considered.

A lid is required for stacking but is not included with the pallet box. It must be ordered separately from the individual product page.

Drain and lid

A 2-inch drain is included with each model. It facilitates emptying, but the drain and its components must still be checked for compatibility with the product and cleaning methods used.

In addition to allowing the stacking configuration specified by the manufacturer, the lid helps protect the contents and reduce heat transfer caused by leaving the box open.

Frequently asked questions

Does an insulated pallet box keep food cold?

It slows the warming of the contents and helps preserve ice, but it does not actively cool food. Temperature retention depends on the product, amount of ice, lid, ambient temperature and length of use.

Can these pallet boxes hold liquids?

Yes. Their solid walls and bottom retain liquids. A 2-inch drain is included to facilitate emptying. The liquid must be compatible with the polyethylene, drain and sealing components.

Is the lid included?

No. The lid is sold separately. It is required to stack the boxes to the specified heights and provides additional protection for the contents.

Can all four models be stacked to the same height?

No. The CPX318, CPX332 and CPX335 can be stacked up to four high with their lids. The CPX327 can be stacked up to three high with its lid, subject to the allowable loads and operating conditions.

Can the boxes be steam-cleaned or pressure-washed?

Yes. The product specifications indicate that they can be steam-cleaned or pressure-washed. The temperature, pressure, cleaning products and nozzle distance must follow the facility’s procedures and must not damage the polyethylene, drain or seals.

How do I choose between the four capacities?

Compare the required volume, total weight of the contents, available height, required fork access and planned stacking configuration. Agrico Plastiques’ consulting service can assess your application and help identify a compatible model.
