ColdShip's cotton blend liners are built from post-industrial reclaimed fiber — resistant to moisture, heat, and deformation. Four film barrier configurations are available to fit your ideal packout. # 0 Virgin resources Cotton is post-industrial fiber # 4 Film barrier options Transparent, opaque, open edge, full encapsulation Cotton blend is derived from cotton, polyester, nylon, linen, wool, and elastane, among other fibers reclaimed for reuse. # ↓ Cost vs. specialty fiber Optimized supply chain cost # ✓ Consistent supply Cotton availability reduces sourcing risk vs. PUR and other oil derivatives --- ![product_photo_denim](https://coldship.com/hs-fs/hubfs/product_photo_denim.jpg?width=1080&height=1440&name=product_photo_denim.jpg "product_photo_denim") Cotton blend liner — open edge configuration with Metalized film barrier.     ![denim chat](https://coldship.com/hs-fs/hubfs/denim%20chat.png?width=1254&height=1254&name=denim%20chat.png "denim chat") Cotton blend liner — Fully wrapped configuration.      ## Cotton Blend Liners ColdShip's cotton blend liners use post-industrial reclaimed fiber — not virgin resources. The blend combines cotton with complementary fibers to deliver durability, insulation, and moisture management in a single liner. Four outer film barrier configurations are available — transparent, opaque, open edge, or full encapsulation — so the liner fits your specific fulfillment and product protection requirements without modification. | Film Barrier Option | Ideal for... | | --- | --- | | Transparent | Product visibility through packaging | | Opaque | Light-sensitive or branded contents | | Open Edge | Easy loading at pack station | | Full Encapsulation | Maximum containment and moisture barrier | | Specification | Value | ASTM Standard | | --- | --- | --- | | R-Value | **~3.7 per inch (R3.69/in)** | ASTM C518 | | Thermal Conductivity | **0.040 W/m·K** | ASTM C518 | | Composition | **Cotton Blend** | — | | Thickness Available | **.5-4"** | — | - Post-industrial material — less virgin fiber resources in your supply chain - Resistant to wear, tear, and deformation — maintains liner integrity across the transit cycle - Cotton availability ensures consistent sourcing — lower risk of supply disruption than specialty fibers - Lower cost basis than specialty insulation fiber — optimizes cost per shipment across the supply chain [Request Samples](mailto:sales@coldship.com) Download Spec Sheet --- ## Four reasons buyers switch to cotton blend. Post-industrial sourcing. Consistent availability. Lower cost. Thermal performance that holds. | 01 / Cost Efficiency #### Lower cost basis, same liner performance. Cotton runs at a lower cost than most specialty insulation fibers. Using a cotton blend lets ColdShip optimize production cost without sacrificing thermal or structural performance — savings that carry through your per-shipment cost. | 02 / Availability and Sourcing #### Consistent supply. Fewer sourcing surprises. Cotton fiber availability is broad and stable. That depth of supply reduces the risk of material scarcity or production delays — a meaningful advantage for high-volume shippers who can't afford packaging shortfalls.   | | --- | --- | | 03 / Durability and Longevity #### Holds up through the full transit cycle. Blending cotton with complementary fibers — polyester, nylon, elastane, or wool — produces a liner resistant to wear, tear, and deformation. The liner maintains its shape and insulating properties through the transit cycle without breaking down. | 04 / Performance and Versatility #### Configurable for your shipment profile. Blending cotton with complementary fibers — polyester, nylon, elastane, or wool — produces a liner resistant to wear, tear, and deformation. The liner maintains its shape and insulating properties through the transit cycle without breaking down. |     ## The proof is in the fibers. Cotton blend is derived from cotton, polyester, nylon, linen, wool, and elastane, among other fibers. |   #### Strength + longevity. Durability, resistance, and resilient properties. Enhances liner strength for long durations. |   #### Flexibility + fit. Stretchable fiber that allows the liner to conform to box dimensions, minimizing void fill and improving pack efficiency.   | | --- | --- | |   #### Insulation + moisture management. Natural insulating and moisture-wicking properties. Suited to temperature-regulating applications and colder transit environments. |   #### Base fiber + cushioning. Natural cushioning and insulating properties. Post-industrial sourcing eliminates virgin resource use while maintaining consistent fiber quality. |     ## Ready to replace Styrofoam?
