UOFFICE One-Sided Thermoflex Insulated Bubble, 125-feet Wrap x 12" This 12-inch wide roll of Thermal Foil Bubble Roll Wrap combines a layer of small 3/16" bubbles with a reflective foil backing, offering targeted insulation and cushioning for narrower items or smaller packaging applications. The reflective foil effectively minimizes heat transfer, helping to maintain stable temperatures, while the bubble layer provides reliable protection against physical impacts and vibrations encountered during shipping and handling. Perfect for wrapping individual bottles, smaller electronic components, or lining boxes containing temperature-sensitive goods, this 125' x 12" narrower roll offers greater precision and less waste for smaller-scale packaging needs. UOFFICE Thermal Foil Bubble Roll’s lightweight and flexible nature makes it easy to handle and conform to various shapes, providing a secure and thermally regulated environment for delicate and temperature-critical products. Effective thermal radiant barrier: reflects 96% of radiant heat transfer with a thermal resistance R value of 4. 9 to 14. 1
