Premium Bubble-Foil Insulated Pouches
Premium Bubble-Foil Insulated Pouches
Thermapack Double insulated pouches offer outstanding thermal protection. They comprise of a dual-foil outer layer with a robust bubble membrane for superior temperature control in transit. The Premium Bubble-Foil Insulated Pouches are designed to protect your chilled, frozen, pharma and other temperature-sensitive shipments from external temperature changes that can damage goods when exposed.
Why choose Thermapack Double?
Thermapack Double is a high-performance insulated chilled packaging material designed to keep products at a stable temperature, during transport or storage. It’s made using a foil–bubble–foil construction, where a bubble membrane is sandwiched between two layers of genuine aluminium foil. This combination creates a lightweight but highly effective thermal barrier.
Because the foil reflects up to 97% of radiant heat and the bubble layer reduces conduction, Thermapack Double offers insulation comparable to much bulkier materials—such as thick polystyrene—while remaining just a few millimetres thick.
