Instant Cold Packs: 1.5x Cooling, Eco & Multi-Use

In modern society, instant cold packs have become indispensable cooling tools, widely used in food preservation, pharmaceutical transportation, and cold therapy for sports injuries. With continuous technological advancements, traditional cold packs increasingly face challenges such as short cooling durations and inconvenient usage. Through our proprietary internal material formula, our company has successfully enhanced the cooling performance of instant cold packs, overcoming the limitations of traditional urea-based formulas. Compared to urea-based products on the market, our cold packs not only extend cooling durations by over 1.5 times but also offer greater convenience, particularly due to the innovative fixed water pouch design, ensuring a hassle-free user experience.

Working Principle of Instant Cold Packs

The fundamental principle of instant cold packs relies on chemical reactions to generate cooling effects. Traditional cold packs typically employ a urea-water pouch formula. When external pressure or impact is applied, the water pouch ruptures, triggering a chemical reaction between water and urea. This reaction produces a significant endothermic effect, rapidly lowering the temperature and delivering immediate cooling.

However, traditional urea-based formulas suffer from short cooling durations, making them inadequate for scenarios requiring prolonged cooling, such as food delivery, travel-related food preservation, or temperature-sensitive pharmaceutical logistics. To address this issue, our team conducted extensive R&D and testing, ultimately introducing a next-generation cold pack with an advanced internal formula.

Our Innovative Formula: Enhanced Cooling Performance

Unlike traditional urea-based formulas, our instant cold packs utilize a proprietary internal compound formula, scientifically optimized to significantly extend cooling efficiency. By incorporating high-efficiency chemical reactants and advanced material technology, our cold packs absorb heat more rapidly, achieving longer-lasting cooling effects.

Based on test data, our new formula extends cooling durations by over 1.5 times compared to conventional urea-based cold packs. Under identical conditions, this ensures temperature-sensitive products (e.g., pharmaceuticals, perishable foods) remain within safe temperature ranges during transport and storage, mitigating risks of spoilage or degradation caused by temperature fluctuations.

Fixed Water Pouch Design: Simplified Usability

A common drawback of traditional cold packs is the unstable positioning of the water pouch, which may shift during handling, compromising cooling performance. To resolve this, we redesigned the water pouch fixation mechanism. Using specialized material engineering, the water pouch remains securely anchored inside the pack, eliminating displacement or deformation during use.

This innovation not only enhances user convenience but also ensures consistent and uniform cooling. During transportation, the water pouch remains unaffected by vibrations or compression, guaranteeing reliable chemical reactions and stable cooling performance.

Versatile Applications

Our instant cold packs excel in diverse scenarios due to their superior cooling performance and user-friendly design. Key applications include:

Food Preservation
Whether for supermarket refrigerated goods or food delivery services, our cold packs effectively extend freshness. In delivery scenarios, they maintain optimal low temperatures over extended periods, preventing food spoilage due to heat exposure.

Sustainable Ice Blocks: Green Cold Chain Solutions

As industries prioritize environmental responsibility, sustainable ice blocks are revolutionizing temperature-controlled shipping. Traditional refrigerant packs containing plastics and toxic gels are increasingly replaced by plant-powered alternatives that protect both products and the planet. These next-generation cooling solutions combine natural phase-change materials (PCMs) with smart design to deliver superior performance while minimizing ecological impact.

The true breakthrough lies in the thermal efficiency of bio-based PCMs. Derived from renewable plant sources, these compounds absorb 30% more thermal energy than conventional gels while maintaining precise temperature ranges (2-8°C or 15-25°C). For vaccine transport and perishable food logistics, this translates to 40% longer cooling durations – a game-changer for transcontinental shipments. Pharmaceutical companies report 99.3% product integrity rates when using PCM blocks versus 87% with traditional methods.

Durability meets circular design in modern eco-blocks. High-grade HDPE shells withstand 500+ freeze cycles without cracking, while fully recyclable construction diverts 1.2 tons of plastic waste per 10,000 units from landfills. Leading manufacturers now offer closed-loop回收 programs, where used blocks are repurposed into new cooling products or construction materials.

Smart cooling integration pushes boundaries further. IoT-enabled blocks with embedded sensors provide live temperature mapping (±0.5°C accuracy), while blockchain-tracked data ensures regulatory compliance. Emerging innovations include algae-based PCMs that decompose in 18 months and color-changing indicators that validate cold chain integrity upon delivery.

Non‑Toxic Ice Blocks: Safe Cooling & Tempk Edge

Non‑toxic Ice Blocks have become the gold standard for modern cold‑chain shipping and consumer refrigeration because they eliminate the leakage and contamination risks once associated with conventional ammonium‑or calcium‑salt coolants. At the heart of these blocks is a food‑safe, polymer‑bound hydrogel or a phase‑change material (PCM) derived from purified plant oils; both freeze cleanly at set points between –20 °C and +5 °C, then melt slowly, releasing latent heat without producing harmful by‑products. Encased in puncture‑resistant HDPE or PP shells certified under FDA 21 CFR 176.170 and EU Regulation 10/2011, the blocks withstand more than a hundred freeze–thaw cycles while keeping payload variance under ±2 °C—critical for vaccines, biologics, gourmet seafood, or meal‑kit deliveries that face ambient swings of 40 °C during last‑mile transit.

Performance optimization focuses on three vectors. First, latent‑heat capacity: bio‑based PCMs can store up to 300 kJ kg⁻¹, doubling hold time versus plain‑water gels of equal weight. Second, shell geometry: ribbed, flat‑plate, and U‑shaped designs shorten re‑charge time in blast freezers by 25 %, maximizing fleet turns. Third, smart traceability: RFID chips molded into the casing transmit block “state‑of‑charge” in real time, letting 3PL dashboards match coolant capacity to route duration and reducing over‑packing or dry‑ice supplementation. Together these innovations cut spoilage by 30 % and lower overall CO₂ emissions across multimodal networks.

Sustainability is equally important. Non‑toxic Ice Blocks support closed‑loop recycling; end‑of‑life casings are shredded, washed, and re‑extruded into new shells, meeting Extended Producer Responsibility mandates in the EU, California, and several ASEAN markets. Because the internal hydrogels are biodegradable or water‑soluble, disposal poses no risk to soil or groundwater. Consumer brands appreciate the marketing edge: labels can carry NSF or TÜV “food‑contact safe” seals, and QR codes link to LCA dashboards that verify carbon savings—an increasingly powerful differentiator in B2C subscription food services.

Tempk Ice Brick Advantage – Tempk’s Ice Brick leverages a high‑density, food‑grade HDPE body and a proprietary plant‑oil PCM core to deliver up to 72 hours of cold retention. Smooth, seamless walls resist punctures and wipe clean in seconds, built‑in stacking grooves save 15 % freezer space, and sizes from 200 mL to 2 L let shippers fine‑tune load plans—providing longer hold times, lower breakage rates, and greener lifecycle economics compared with generic blocks.
