PCM Gel Pouches

Why gel-form PCM is a niche you can own

• Better payload conformity — gel pouches mold around products, reducing dead air space, improving heat transfer.
• Lighter & safer to handle — no hard corners, less damage risk in transit.
• Flexible pack-out — can be layered or wrapped, perfect for oddly shaped payloads.
• Lower upfront tooling cost — you don’t need custom molds like rigid bottles/bricks.

PCMCOOL SnapGel Pouch

Weight: 150g
Size (mm): 140 x 120 x 15
PCM: 5°C/15°C/18°C/23°C/25°C/28°C

SnapGel is a unique self-recovering, crushable phase-change gel that combines flexibility with durability. When crushed or deformed, it quickly regains its original shape, making it ideal for reusable cooling packs applications. Its phase-change material (PCM) efficiently absorbs and releases heat, providing long-lasting thermal regulation.

PCMCOOL SolidGel Pouch

Weight: 150g
Size (mm): 140 x 120 x 15
PCM: 5°C/15°C/18°C/23°C/ 25°C/28°C

SolidGel, in contrast, is a high-tensile-strength, block-like gel with superior structural integrity. Unlike liquid gels, it resists tearing and maintains shape under pressure, making it perfect for rigid cooling pads, its high thermal capacity ensures prolonged cooling or heating cycles.

Ru Entropy Organic PCM Gel Pouches:
Cost-Effective, Versatile Solutions for Cold Chain & Beyond

Lightweight, lower cost
Ru Entropy delivers a significant cost advantage over traditional HDPE bottle PCM solutions without compromising accuracy. Our organic PCM gel pouches are lightweight—weighing 20% less than HDPE bottle alternatives—reducing shipping costs for cold chain logistics while maintaining the same thermal performance.

Versatile Applications

Our organic PCM gel pouches are primarily engineered for cold chain applications, but when properly designed, these PCM gel pouches can also function as cooling vest inserts or support other innovative cooling and heating applications.
For example, they’ve been successfully integrated into industrial cooling vests for workers in high-temperature environments, providing 4–6 hours of continuous cooling to prevent heat-related discomfort.

Solid-to-Solid Gel for Optimal Protection
This PCM product transitions from solid to solid gel within the temperature range required to protect the items it safeguards (specifically, this gel-form PCM is hard in its solid phase and transforms into a soft gel in its liquid phase).

Unlike rigid PCM solutions, this flexible gel form allows the pouch to conform to the shape of packaged items, ensuring closer contact and more uniform temperature distribution.

Fitting Any Thermal Packaging Need
The unique property of our PCM creates super-efficient thermal packaging that fills thermal dead zones and can be sized to fit any application. Whether you need small pouches for individual pharmaceutical vials or large custom sheets for pallet-scale freight, our design adapts to your exact packaging needs.

Longer Lifespan & Tailored Temperatures
Importantly, our organic PCM gel pouch differs from the more common water-based gel pouches on the market. Unlike water-based options that lose effectiveness after 5–10 uses, our organic PCM maintains consistent thermal performance even after 50+ reuse cycles.
Ru Entropy offers a series of PCM solutions with different temperature specifications to meet diverse cold chain application needs. From -20°C for deep-frozen biologics to 2–8°C for vaccine transport, each formulation is tailored to specific temperature-sensitive goods.
