PopupLiner™ features patented vacuum-compressed insulation panels that deliver strong thermal protection while shipping and storing flat—helping reduce warehouse space, inbound freight, and handling costs.
The only certified curbside recyclable, paper liner rated for 72-hour refrigerated shipping. Unlike cellulose liners that require special handling, CelluLiner™ goes straight into your recycling bin—nationwide. Experience true satisfaction with insulation that actually gets recycled and proven to keep your products cold.
Ships compressed and flat, reducing warehouse space and inbound freight.
The panels quickly expand and lock together inside the carton.
Available in standard or custom sizes to fit your shipping configuration.
Creates a structured liner without excessive folding, taping, or assembly.
Suitable for frozen and refrigerated products, including food, pharmaceuticals, and other temperature-sensitive goods.
PopupLiner™ is a single, high-performance solution available in different insulation thicknesses and custom configurations
to match your carton size, shipping duration, temperature range, and performance requirements.
Ready-to-order configurations for common carton sizes.
Designed to fit your specific carton dimensions.
Two insulated panels lock together inside the carton.
Available in different thicknesses based on performance.
Thickness is selected based on temperature, transit time, payload & refrigerant.
PopupLiner™ panels arrive vacuum-compressed, allowing them
to be stored and handled efficiently before use. The compact
format helps maximize storage space and simplifies handling
in shipping operations.
Choose the thickness based on your performance requirements. Thicker configurations can provide greater thermal resistance
for more demanding conditions and longer transit times.
Lower Insulation Thickness
Suitable for applications with lighter thermal protection requirements.
Moderate Insulation Thickness
For applications requiring increased thermal resistance.
Higher Insulation Thickness
For applications requiring greater thermal resistance and extended protection.
Higher Insulation Thickness
For demanding applications requiring additional thermal resistance.

PopupLiner™ has been evaluated under controlled thermal conditions using different refrigerants, payload configurations, insulation thicknesses, and shipping profiles. The testing demonstrates its ability to provide reliable thermal protection for both refrigerated and frozen applications.
PopupLiner™ maintained temperatures below 41°F for at least 48 hours under simulated summer ambient conditions.
A separate 60-hour test evaluated PopupLiner™ within a controlled 15–20°C temperature range.
PopupLiner™ maintained temperatures below 41°F for at least 48 hours under simulated summer ambient conditions.

PopupLiner™ combines vacuum-compressed insulation, high-performance thermal panels, and reflective barriers to transform a standard shipping carton into a temperature-controlled shipping solution.
Tear open the outer vacuum sleeve holding multiple compressed panels.
Place the two insulated expanded panels inside a standard shipping carton, where they interlock to create a fully insulated interior.
Add temperature-sensitive products along with the appropriate refrigerant, such as gel packs or dry ice, based on the shipping requirements.
Close the carton and ship as usual. PopupLiner™ provides thermal protection while remaining lightweight and space-efficient.
PopupLiner™ can be configured for a wide range of temperature-sensitive shipments, from frozen food to pharmaceuticals and other products requiring refrigerated or frozen protection.
Protect frozen meats, seafood, ice cream, meal kits, and other frozen products during extended transit.
Support temperature-controlled shipping for vaccines, medications, and other pharmaceutical products.
Help maintain appropriate temperatures for refrigerated foods, dairy, prepared meals, and other perishables.
Provide an insulated shipping environment for products that require controlled temperatures during transportation.
PopupLiner™ can provide effective thermal protection for shipments lasting approximately 48–72+ hours, depending on the packaging configuration, payload, refrigerant, and shipping conditions.
PopupLiner™ is designed primarily as a shipping liner. Contact IPC to determine the best configuration for your specific application and reuse requirements.
Yes. IPC can manufacture custom sizes to fit your specific carton and shipping requirements.
PopupLiner™ can be used for a wide range of temperature-sensitive products, including frozen foods, refrigerated products, pharmaceuticals, vaccines, and other temperature-sensitive goods.
Yes. PopupLiner™ can be used with dry ice and other refrigerants to support extended thermal protection.
The insulation panels are vacuum-compressed, allowing them to ship and store in a compact form. They expand when opened and are assembled inside the shipping carton.
The current standard minimum order quantity is 1,000 sets/pieces per size. Custom requirements can be discussed with IPC.
PopupLiner™ provides a more space-efficient alternative to bulky molded coolers. It ships compressed, requires less storage space, and can be configured to fit the shipping carton.
