Meet FrostIris 4x5 Inch Ice Packs

Designed to replace bulky ice and messy melting, FrostIris 4x5 inch ice packs slide into coolers, lunch boxes, and bags with ease. Built with New Cooling Technology, these slim packs aim to keep foods and drinks cooler for longer windows while maintaining a safe, non-toxic profile that’s suitable for daily reuse.

Whether you’re packing hearty sandwiches for school, keeping perishables fresh on a road trip, or loading a shipping box with chilled goods, these flexible packs adapt to your situation without sacrificing space or convenience. Their lightweight, paper-thin profile after soaking makes them easy to stash and quick to deploy in a wide range of containers.

Key benefits at a glance

• Potentially longer cooling than loose ice in typical coolers, with durations that can span 24 to 48 hours depending on use and conditions.
• 100% BPA-free and non-toxic materials designed for everyday handling and reuse.

• Puncture-resistant construction built for repeated use, helping you reduce mess and waste.
• Compact 4 by 5 inch size provides versatile placement across a range of containers and setups.

How to use and care

• Activation: soak in clean water for 5–10 minutes, then wipe the surface dry to prevent sticking when frozen.
• Freezing: place in the freezer for at least 8 hours before use for best results.
• Reuse: after use, rinse if needed and air-dry; store flat to save space and keep them ready for next time.
• Notes: water-activated packs may feel slick until dry; the design aims to be durable through daily handling.

Ideal uses and scenarios

From beach days and fishing trips to shipping perishable foods and daily lunch packing, these packs are designed to curb melting mess while keeping contents cool. The 4x5 inch footprint fits many containers, coolers, and lunch bags, making them a flexible choice for travelers and families alike.

What makes FrostIris different

• Lightweight and slim profiles that slip into tight spaces without adding bulk.
• Side water absorption helps manage moisture and minimizes leakage risk during handling.
• Activated packs offer an efficient way to replace ice while supporting multiple uses from one pack set (10 packs can approximate the mass of ice when hydrated).

Note: This cooling aid is designed to support food freshness and chilling in various settings; results vary with external conditions and container performance.
