Cold Packs, Re-Freez-R-Brix®, Moisture-Safe and Biodegradable Options

Cold packs add conditioned thermal mass to insulated shipping systems. The selection includes Ice-Brix® cold packs, rigid Re-Freez-R-Brix® bricks, Tech Pack moisture-safe packs and specifically identified biodegradable packs. Sizes and weights vary by product, so choose from a validated thermal plan rather than carton size alone.

Choose the Pack Style and Thermal Mass

Flexible packs conform more readily around products, while rigid bricks hold a fixed shape that can simplify repeatable placement. Available examples include small Ice-Brix® packs beginning at 3 ounces and Re-Freez-R-Brix® formats beginning at 7.5 ounces, with larger weights offered in each family. The correct total coolant mass depends on payload, insulation, route, duration and season.

Moisture-safe products are designed to manage exterior moisture differently from standard packs, but the name does not make the finished shipment leakproof. Biodegradable claims apply only to the products specifically identified that way and should be reviewed against the supplier's disposal conditions. Do not extend either property to every cold pack.

Condition and Place Packs Consistently

Follow the exact conditioning method for the selected product. Freezing time, freezer temperature, pack orientation and staging can affect starting condition. Arrange packs according to the validated design and include separation where direct contact could freeze or damage the payload. Fill voids without blocking the intended thermal path or crushing the product.

A cold pack does not guarantee that contents will remain chilled or frozen. Test the complete package through representative ambient and transit conditions, and establish acceptance criteria for arrival. Revalidate after changes to pack weight, supplier, insulation, payload mass, carrier service or seasonal profile.

Cold Pack Family Guide

Family Starting Selection Question Important Check
Ice-Brix® cold packs What flexible-pack weight and footprint fit the layout? Conditioning, total mass and placement
Re-Freez-R-Brix® Would a fixed brick shape improve repeatability? Dimensions, weight and available interior space
Tech Pack moisture-safe Is exterior moisture management needed? Exact construction and package leak controls
Biodegradable packs Is the documented disposal attribute required? Exact product claim and disposal conditions

Cold Packs for Insulated Shipping FAQs

Do cold packs guarantee a product temperature?

No. The complete package must be designed and tested for the route and season.

What is the difference between flexible packs and bricks?

Flexible packs conform around contents, while bricks retain a more fixed shape.

Are all cold packs biodegradable?

No. That claim applies only to specifically identified products and documented conditions.

Can a frozen pack touch freeze-sensitive goods?

Only when the validated packout permits it; a separation layer may be required.
