23°C Phase Transition Pack - 100 g

Smarter temperature control for sensitive shipments.

This 100 g Phase Transition Pack is designed to help buffer parcel temperatures around ~23°C, making it ideal for shipping temperature-sensitive items like live aquarium plants, shrimp, and other delicate goods.

Unlike standard ice packs, this isn’t about making things cold—it’s about keeping things stable.

Why It’s Different

Traditional ice packs create sharp temperature drops.
Phase transition packs work differently.

They absorb and release thermal energy as they move through their transition range, helping reduce sudden temperature swings inside your packaging.

Result:

• Less thermal shock
• More stable conditions
• Safer transit for sensitive items

A more controlled approach—rather than the classic “throw in ice and hope for the best.”

Compact & Practical

At 14 × 14 cm and 100 g, this pack is:

• Compact enough for small parcels
• Easy to position inside insulated packaging
• Large enough to add meaningful thermal buffering

Best Used With

For optimal performance, use alongside:

• Styrofoam boxes or insulated liners
• Void fill (to reduce air gaps)
• Sensible packing layout
• Proper dispatch timing

It’s a support tool, not a standalone solution—combine it with good packing practices for best results.
