Bubble Paper Liners are a packaging insulation solution designed with the cold chain industry in mind, reducing cost and increasing product recyclability. With our Bubble Paper technology core, they can be used to ship food, beverages, medical supplies, and other temperature-sensitive payloads. Each “kit” contains two liners— an “A liner” and a “B liner” both 1.5 inches thick. The two liners fit snug into a variety of square box sizes, creating a barrier on all sides.
