The Recyclable One-Piece.

Coldkeeper’s continues to revolutionize the cold-chain industry! Introducing the only Curbside Recyclable Paper One-Piece Thermal Insulated Box Liner!

Made with postindustrial paper products, these liners are not only fully curbside recyclable but also fully repulpable. The liners ship flat to save freight and are suitable for shipments of ambient, fresh, refrigerated, and frozen products between 24 to 72 hours + (Use with gel packs or dry ice to extend transit times).

Immensely popular with pharmaceutical companies and direct to consumer food delivery businesses, a primary advantage of this innovative solution is its ability to ship flat and save on inbound freight and warehousing costs. Additionally, the design permits a quick turnaround for custom sized liners without prohibitive tooling costs, which allowed us to pioneer the introduction of seasonal use liners to further minimize costs (thinner liners for winter, thicker for summer, etc.). The patented one-piece design also allows for effective and efficient product implementation by fulfillment facilities versus a two piece counterpart.

Feel free to reach out today to our sales and customer service team to learn more about this exciting new product line. Stock sizes range from 10 to 12 cube; custom sizes available upon request.
