Cool Barrier Bubble Mailers measure 24 x 20" and deliver dual-layer protection through a 3/16" bubble interior paired with a reflective thermal outer material. The bubble lining absorbs impact and vibration during transit, while the thermal layer slows heat transfer to help contents maintain target temperature ranges throughout the shipping cycle.
These mailers are well suited for e-commerce fulfillment of perishables, direct-to-consumer food shipments, pharmaceutical distribution, and specialty retail requiring cold-chain integrity. The puncture-resistant, water-repellent construction holds up in varied handling environments, from sortation facilities to last-mile delivery.
Each mailer features a built-in peel-and-seal adhesive strip for fast, secure closure without additional tape or equipment. Cases contain 50 mailers and weigh approximately 15.88 lbs per case.
