Tailored pack-outs

Thermal protection built around your shipment

The right pack-out depends on your product, its target temperature, and how long it's in transit. We'll work with you to choose the right cooler size, wall thickness, and refrigerant configuration for your required temperature range and shipping duration.

Actual thermal performance depends on the complete pack-out, including payload, refrigerant conditioning, and external shipping conditions.

Frequently asked questions

What is EPS?

EPS stands for expanded polystyrene. It is a lightweight, rigid foam that provides thermal insulation and protective support in shipping containers.

How do I choose the right cooler size?

Allow space for your product, inner packaging, and required refrigerants. Share your complete packout dimensions, and we can help recommend a cooler size and wall thickness.

What sizes and wall thicknesses are available?

Standard interior sizes are 8″ × 6″ × 4″, 8″ × 6″ × 7″, and 12″ × 10″ × 7″. Standard wall thickness options are 1″ and 1½″. Contact us for available size and thickness combinations or to discuss a custom mold.

How does wall thickness affect the cooler?

Wall thickness influences thermal insulation and the overall dimensions of the shipper. The right choice depends on your payload, refrigerants, target temperature, and transit time.
