Cold Chain & Durability: Why Sæplast Triple-Wall Containers Outperform Single-Wall Alternatives

In industries like fish & seafood, meat & poultry, pet food and food processing, where maintaining product quality is paramount, two critical factors determine success: cold chain reliability and container durability. This is where Sæplast’s triple-wall insulated containers outshine traditional single-wall plastic containers—delivering superior performance in every aspect.

Cold Chain Confidence

Temperature stability isn't just about freshness—it directly impacts food safety, shelf life, and financial return. Sæplast containers are engineered with triple-layer, closed-cell PE insulation, maintaining internal temperatures for extended periods without relying heavily on ice or active cooling.

In contrast, single-wall containers lack insulation, making them highly susceptible to temperature swings. This can lead to product degradation, flavor loss, and spoilage.

Durability That Drives Sustainability

Sæplast containers are designed to withstand the harshest handling conditions for over a decade, offering:

• Impact resistance
• Seamless construction
• Easy repairability for multiple usage

Single-wall containers often crack or degrade under stress and require frequent replacement, driving up both waste and operational costs.

Sæplast’s longevity supports sustainable operations by reducing replacement frequency and lowering the environmental footprint.

Head-to-Head Comparison

Cold Chain Performance

Feature	Sæplast PE Containers	Single-Wall Plastic Containers
Thermal Insulation	✅ Triple-layer, insulated PE core	❌ No insulation
Temperature Stability	✅ Minimizes fluctuation, maintains product integrity	❌ Prone to spikes and spoilage
Cold Chain Continuity	✅ Maintains cold during long transport	⚠️ Requires frequent ice or chilling

Conclusion: Sæplast ensures a stable, efficient cold chain. Single-wall containers introduce risk and inconsistency.
