Sonoco Protective Solutions

When you're shipping temperature-sensitive pharmaceuticals, biologics, or perishable food, the difference between a product that arrives usable and one that doesn't often comes down to what's packed alongside it. Sonoco Protective Solutions builds cold-chain packaging components engineered to hold a stable temperature range throughout transit — the kind of reliability that regulated shipments demand.

This collection features the Sonoco PolarPack Refrigerant Gel Pack (PP6), a gel-and-polyethylene coolant designed for safe transport of food, pharmaceutical, and medical products. Gel packs like the PP6 work by absorbing and releasing thermal energy slowly, buffering your payload against temperature swings during shipping delays or warm loading docks. Unlike loose ice, they won't leak melted water into a shipper, and they can be pre-conditioned (frozen or refrigerated) to target the range your product requires — whether that's a frozen shipment or a controlled 2–8°C refrigerated window.

Buyers typically ask how many gel packs a shipment needs and where they sit inside the box. The answer depends on your payload volume, insulation, ambient conditions, and expected transit time, so many operations validate a configuration through packout testing before standardizing. The PP6's polyethylene film construction is puncture-resistant and holds up to repeated freeze-thaw cycles, making it practical for both one-way shipping and reusable programs.

For facilities that manage their own packouts, keeping validated coolants on hand means fewer temperature excursions and less product loss.
