Protect temperature-sensitive products against extreme ambient temperatures with a lightweight, collapsible insulated box liner designed for refrigerated shipments up to 24 hours.
Protect temperature-sensitive products against extreme ambient temperatures with a lightweight, collapsible insulated box liner designed for refrigerated shipments up to 24 hours.
CooLiner® is a lightweight, one-piece insulated box liner made with reflective metalized film and air-bubble insulation to protect temperature-sensitive products during refrigerated shipments. Its completely collapsible design arrives folded for efficient storage and handling, then expands easily inside the carton.
The gusseted construction creates an insulated interior around the product, with an optional peel-and-seal adhesive lip for easy closure.
Compact when collapsed, CooLiner® requires less storage space before use and can help improve efficiency in shipping and packing operations.
The completely collapsible one-piece liner opens directly inside the shipping carton, simplifying the packing process and reducing assembly work.
An optional peel-and-seal adhesive lip provides a simple closure method for securing the liner around the carton opening.
The gusseted liner features a water-tight, leak-resistant bottom designed to help keep products protected from leakage during transit.
IPC manufactures custom-sized CooLiner® liners to fit specific carton dimensions and shipping requirements.
CooLiner® raw materials are approved by the FDA for incidental food contact, according to the existing product information.
CooLiner® combines a reflective outer barrier, high-strength bonding layer, and engineered bubble insulation to create a lightweight material designed to reduce heat transfer while remaining durable and efficient for shipping.
The existing Materials page describes this as an advanced foil-type material engineered for maximum reflection and minimum absorption, while also being highly puncture-resistant.
The engineered bubble material is designed to resist conductive heat flow while remaining temperature stable. IPC also describes special additives intended to provide a strong structure suitable for the demands of shipping.
For applications requiring additional thermal control, CooLiner® is also available with a dual bubble layer. The additional layer of air pockets provides enhanced insulation for longer-duration temperature protection.
CooLiner® is available in multiple insulation configurations and can be manufactured to fit your carton dimensions. Select the configuration that best matches your cost, protection, and shipping requirements.
Streamlined for reduced costs
A lighter configuration designed for applications where a more economical insulation option is preferred.
Designed for 24-hour refrigerated shipments
The standard single-bubble configuration provides thermal protection for carton-sized refrigerated shipments requiring up to 24 hours of protection.
Dual-layer insulation for increased protection
The double-bubble configuration uses two bubble layers and is described by IPC as providing 20% better protection than the single-bubble configuration.
CooLiner® can be manufactured to your required dimensions, allowing the liner to fit the specific carton and payload configuration rather than forcing your operation to adapt to a standard liner.
SustainaLiner® is an alternative to traditional foil-bubble insulation, designed for customers who place a higher priority on material recyclability. Made entirely from low-density polyethylene (LDPE), this mono-material offers a high-recycling-value option for refrigerated and controlled-room-temperature shipments.
Proven Performance in Real-World Cold-Chain Conditions
CooLiner® has been tested under elevated ambient conditions to evaluate its ability to protect refrigerated products during a 24-hour transit period.
As shown in the graph below, insulating with CooLiner® box insulation resulted in a substantial temperature differential over a 24-hour transit duration.

Expand the collapsed CooLiner® and prepare it for installation inside the carton.
Place the CooLiner® inside the corrugated carton so the insulated walls surround the product area.
Place the temperature-sensitive product and appropriate refrigerant inside the insulated carton.
Close the liner using the optional peel-and-seal adhesive lip, then close and prepare the carton for shipment.
Explore how CooLiner® provides lightweight thermal protection across a range of temperature-sensitive shipping applications. See how the liner can be integrated into different packaging configurations and product shipments.
CooLiner® is designed for up to 24 hours of thermal protection under defined refrigerated shipping conditions. Actual performance depends on factors such as ambient conditions, payload, refrigerant, starting temperature, and shipping configuration.
The reflective metalized layer helps reflect radiant heat, while the bubble layer helps resist conductive heat transfer.
CooLiner® is available in Lite, Single Bubble, and Double Bubble configurations.
