High-Performance PCM Cooling Elements for Deep-Freeze Shipping
Our dedicated category for deep-freeze dispatch introduces advanced PCM cooling cushions and PCM ice packs specifically engineered for shipping frozen products. Whether you handle frozen food, BARF pet nutrition, pharmaceutical goods or lab samples, our solutions maintain defined temperature levels of -16 °C and -21 °C for extended durations – ensuring reliability in modern cold-chain logistics.
What is PCM?
PCM stands for Phase Change Material: a material that absorbs or releases latent heat during its phase transition, maintaining a near-constant temperature. For example, a PCM pack at -21 °C holds that temperature over hours – enabling precise deep-freeze transit without deviation.
Key Benefits of PCM Cooling Cushions & Ice Packs
- Stable deep-freeze performance: Ideal for -16 °C and -21 °C shipments of frozen goods.
- Pharmaceutical & laboratory compliance: Secure cold chain for vaccines, diagnostics and biotech.
- Reusable and cost-efficient: Many PCM ice packs are designed for multiple uses, lowering lifecycle cost.
- Tailored temperature profiles: Choose from several gradients for your specific frozen shipping needs.
- Optimised for deep-freeze logistics: Suitable for multi-day transport, e-commerce frozen delivery and sensitive supply chains.
- Wide range of formats: Sizes from ~200 g to 1000 g (or more) to suit parcel shipping and carton integration.
- Customisable solution: Branding, logo imprint, bespoke weights and shapes available for your packaging concepts.
Applications Across Industries
- Frozen food & retail logistics: Meat, seafood, ice cream, convenience food for direct-to-door delivery.
- Pet nutrition & BARF shipping: Frozen raw-food products requiring constant deep-freeze control.
- Pharma, biotech & laboratory: Frozen diagnostics, biological samples, medical transport with -20 °C class requirements.
- E-commerce & subscription fulfilment: Brands delivering frozen packages to consumers with high performance and sustainability standards.
Best Practices for Using PCM Cooling Systems
1. Pre-condition PCM packs correctly
Ensure your PCM ice packs are frozen or conditioned to their rated temperature (e.g., -25 °C for -21 °C pack) before use. This step is critical for optimal deep-freeze retention.
2. Combine with quality insulation
Use your PCM elements inside high-performance insulated packaging such as:
- Paper-based insulated boxes
- Reuse-capable thermo boxes
- Thermal containers designed for cold-chain logistics
Such combinations maximise the latent-heat advantage of PCM and ensure cost-efficient deep-freeze transport.
3. Pack and position correctly
Place the PCM packs adjacent to your shipping goods and fill any voids. This ensures a consistent temperature envelope and prevents temperature excursions.
Which solution suits you – PCM cushion, ice pack or pack?
Depending on your needs, choose from:
- PCM cooling cushion: flexible flat format for direct contact with your goods.
- PCM ice pack: robust reusable format for parcel shipping and multi-use.
- PCM cold-pack: generic term covering all PCM modules in various sizes and temperature classes.
