What Are Our Ice-Cold Gel Packs Made Of—And Why Does It Matter?

Introduction

In industries like food logistics, pharmaceuticals, and veterinary care, maintaining temperature control isn’t optional—it’s essential. At Ice-Cold Gel Packs, we take every detail seriously, starting with the materials we use to manufacture our products.

In this blog, we’ll break down exactly what our gel packs are made of—and why that matters for durability, performance, and safety.

1. The Outer Layer: High-Resistance Polymer for Maximum Durability

Each Ice-Cold Gel Pack is encased in a high-resistance polymer film designed to endure the rigors of transport, storage, and repeated use:

• Polyethylene (PE): Flexible, waterproof, and tear-resistant

• Polypropylene (PP): Offers excellent thermal and chemical stability

• Multi-layer laminate: Combines materials to enhance sealing and longevity

These materials make our gel packs highly resistant to punctures, leaks, and ruptures—even after multiple freeze-thaw cycles.

2. The Gel Inside: Stable, Long-Lasting Cooling

Inside every Ice-Cold Gel Pack is a specialized cooling formula that ensures consistent, long-term cold retention. The gel includes:

• Purified water: Forms the cooling base

• Superabsorbent polymers (e.g., sodium polyacrylate): Trap water in a gel-like state to prevent spills

• Preservatives and stabilizers: Maintain hygiene and extend shelf life

This formula stays colder longer than regular ice, without excess moisture or mess—perfect for temperature-sensitive applications.

3. Why Should You Care About the Materials?

Understanding what goes into our gel packs helps you make a smarter choice for your shipping and storage needs. Here’s what sets our materials apart:

• Safe: Suitable for indirect contact with food and pharmaceuticals

• Reusable: Built to last, helping reduce recurring costs

• Thermal stability: Consistent performance during long or sensitive shipments

• Eco-conscious: A cleaner, more sustainable alternative to dry ice or single-use coolants

Conclusion

Ice-Cold Gel Packs are crafted with premium materials to give you maximum confidence and reliable performance. From their tough, multi-layer exterior to their advanced, long-lasting cooling gel, every detail is designed to safeguard your temperature-sensitive shipments.
