KoolPak Instant Heat Pack

Instant Single-use Heat Therapy Hot Pack

A self-activating, single-use heat pack designed to deliver fast, controlled warmth wherever heat therapy is required, without electricity, microwaves or preparation.

Best for: clinical procedures, first-aid kits, workplace health settings, and short-term heat application for muscle and joint discomfort.
Not ideal for: prolonged or repeated daily heat therapy where a reusable solution is preferred.

• Designed for reliable, on-demand heat delivery
• Suitable for professional healthcare environments
• Simple activation with no external equipment

Expected comfort and use timeline

First use: Once activated, the pack begins warming within moments. Users typically notice a gradual, comfortable rise in temperature rather than an intense burst of heat.

Short-term use (minutes): Heat remains consistent and evenly distributed across the pack surface, supporting comfort during clinical procedures or while resting affected areas.

Ongoing use (up to 40 minutes): The pack continues to emit warmth for approximately 40 minutes at room temperature. Heat slowly reduces as the contents cool, signalling the natural end of use.

What is it?

The KoolPak Instant Hot Pack is a compact, disposable heat therapy solution activated by a simple manual process. It is designed for situations where immediate heat is required and traditional heating methods are impractical or unavailable. Once activated, the pack produces controlled warmth suitable for therapeutic and procedural use.

Its single-use format supports hygiene and infection control, making it particularly suitable for clinical environments, emergency kits, and mobile healthcare settings.

Who is it for?

This instant hot pack is intended for use by healthcare professionals, first-aiders, occupational health teams, and individuals seeking short-duration heat therapy. It is commonly used in:

• Hospitals and clinics
• Phlebotomy and vaccination settings
• Workplace first-aid stations
• Sports and rehabilitation environments
• Home first-aid kits where rapid heat access is needed

What does it help with?

Heat therapy is widely used to promote comfort and tissue relaxation. The KoolPak Instant Hot Pack is designed to support this process in a practical, controlled way.

• Muscular aches: may help relax tight or overworked muscles
• Joint stiffness: supports gentle warming of stiff joints
• Soft-tissue discomfort: can reduce the sensation of tightness
• Pre-procedure warming: supports vasodilation prior to venepuncture or injections

How does it work?

The pack contains a sealed solution of sodium thiosulfate and water. Activation triggers a controlled exothermic reaction that releases heat. This process does not require electricity, microwaves, or external heat sources.

The design ensures that heat is released gradually and spread evenly across the surface of the pack, helping to avoid hot spots and supporting consistent comfort during use.
