Thick Corrugated Heat Insulation Sleeves
Safety is non-negotiable in foodservice packaging. Our thick corrugated sleeves are engineered for extreme heat protection, using the natural insulating properties of corrugated structure to minimize heat transfer. This makes them the ideal choice for extra-hot beverages, high-volume operations, and businesses that prioritize customer safety.
The Science of Corrugated Insulation:
The corrugated structure creates an air gap between the cup and the outer surface. Air is a poor conductor of heat, so this gap significantly reduces heat transfer, keeping the outer surface comfortable even when the cup contains near-boiling liquid.
