Ship temperature-sensitive items safely with lightweight cool shield thermal bubble mailers. These thermal envelopes feature a protective exterior made from puncture-resistant polypropylene metallic that repels water and heat. They also have a 3/16” air bubble interior, pressure sensitive closure, and a strong seamless bottom. Insulated mailers are the ideal short-term shipping solution for perishable items like food, cosmetics, or pharmaceuticals.
To use these cool shield bubble mailers, place contents inside, remove the adhesive strip, and apply slight pressure to close. If contents are sensitive to heat, we encourage the addition of a cooling agent like a gel or cool pack to help repel heat and maintain a desired temperature during transit.
Cool Shield Thermal Bubble Mailers are made with a polyethylene interior and polypropylene metallic exterior.
