Bubble foil is a lightweight and highly efficient thermal insulation material, composed of a composite structure featuring an aluminum foil layer bonded to a polyethylene (PE) bubble film. Its internal enclosed air bubbles significantly reduce heat conduction, while the reflective surface of the aluminum foil reflects up to 97% of radiant heat, thereby delivering exceptional thermal insulation performance.
