Product Specification

Product Introduction

Our Biodegradable Super Absorbent Polymer (SAP) Sodium Polyacrylate Ice Pack is designed for high-performance cold chain and temperature-control applications. Made from eco-friendly biodegradable SAP materials, the ice pack quickly absorbs large amounts of water and transforms it into a gel, providing long-lasting cooling while maintaining excellent leak-proof stability. It can be used safely in food transportation, medical cold storage, outdoor activities, and everyday cooling needs.

Engineered for efficient moisture absorption and prolonged cooling retention, this product is an ideal choice for users seeking reliable, sustainable, and convenient cooling solutions.

 FAQ

1. What is the ice pack made of?

The ice pack uses biodegradable sodium polyacrylate super absorbent polymer (SAP) sealed inside a durable, leak-proof film.

2. How do I use this ice pack?

Soak the ice pack in water for 3–5 minutes until fully swollen, wipe off excess water, and place it into the freezer for several hours before use.

3. Is the material safe for food transportation?

Yes. The SAP is non-toxic, odorless, and compliant with food-safe handling standards. It is widely used in fresh food and medical cold chain logistics.

4. How long can the ice pack stay cold?

Cooling duration varies by size and environment but generally lasts 3–15 hours, significantly longer than traditional gel ice packs due to high water retention.

5. Is the product environmentally friendly?

Yes. The SAP is biodegradable, and the outer film can be made with recyclable materials upon request.

6. Can the ice pack be reused?

Most designs can be reused multiple times as long as the outer film remains intact.

7. What sizes are available?

We offer standard sizes (such as 100g, 200g, 400g) and fully customizable specifications depending on application requirements.

8. Does the ice pack leak when it melts?

No. The SAP converts water into a stable gel that doesn’t liquefy, ensuring clean and safe usage throughout the cooling cycle.
