CooLiner insulated box liners are lightweight, easy-to-use, made from environmentally friendly materials, and provide effective thermal protection for containers of any size. The thermal liners are completely collapsible for easy shipment and efficient handling.
CooLiner insulated shipping boxes can be used for shipping perishable food items, pharmaceuticals, dairy products, and any other temperature-sensitive products.
Made of recyclable #7 material*, CooLiner foil insulated bubble bags are recommended for protecting refrigerated, carton-sized shipments against extreme ambient temperatures for up to 24 hours. When used together with a corrugated shipping box, the one-piece CooLiner creates an effective insulated shipping box that arrives folded in a compact format for low-cost transport and storage.
Knowing that your temperature-sensitive products are protected against extreme temperatures throughout the cold-chain distribution system gives you the confidence to ship your goods in any season, to any location. Shipping with the proper type of 3D insulation means ‘product loss’ is much less of a concern.
Using the same innovative technology found in our foil-bubble thermal blankets and pallet covers, our gusseted insulated box liners use passive energy reflection to insulate your products throughout the entire shipping duration.

Refrigerated Product – 24-Hour Transit in Summer
The efficacy of the CooLiner thermal box liner was tested by comparing it to that of a 1/2″ styrofoam insert. Two test samples were placed under extremely high ambient temperature and the thermal performances were compared.
As shown in the graph below, insulating with CooLiner box insulation resulted in a substantial temperature differential over a 24-hour transit duration.

CooLiner is a revolutionary type of insulation made from metalized films and air bubbles. The combination of these materials creates a silver bubble wrap that provides high-performance temperature control against extreme temperatures.
These cold shipping boxes are simple, easy-to-use, come in any custom size, and are available in various forms: bags, covers and roll stock. They are summer liners recommended for protecting carton-sized shipments at refrigerated temperatures for shipments lasting 24 hours or less.
Unique Dual Layer Technology
IPC utilizes proprietary reflective materials, not available to insulated box liner manufacturers, that provide the perfect combination of heat reflection and mass. Similar materials, when presented with a higher relative thickness, do not necessarily provide the best heat resistance. Light (low thermal mass) and highly reflective insulated bubble wrap can provide better heat resistance. This critical combination has a large net effect on the performance of insulated shipping boxes such as CooLiner.
The foil reflective layer in CooLiner effectively blocks radiating heat from the environment, even after it has entered through the walls of a carton. This foil layer is even more effective when exposed to open air, such as when it is used as a pallet cover.
Our Exclusive Bubble Layer
IPC’s bubble material provides a unique structure that resists conductive heat flow. Again, the correct weight (gauge) is critical in the material’s performance capacity. Thicker, heavier films, although more durable, have higher thermal mass that can actually exacerbate heat flow.
Perfected after 11 years of careful research, IPC’s bubble technology presents time-tested, real world efficacy.

CooLiner insulation material is superior to similar products from other manufacturers or suppliers for the following reasons:
- It offers unparalleled temperature-control performance.
- It has a space-saving design that allows efficient shipping and storage.
- It resists becoming cracked or broken during transport.
- It is watertight, which prevents leakage during transport.
- It is easily disposed of.
- It is available at competitive wholesale prices.
CooLiner cold shipping boxes provides cost-saving advantages over conventional foam-type insulation products.
CooLiner insulated containers are easy to store and use.
Because they require little space when folded, CooLiner products present more efficiency in the pack area, whereby less work is required to move them into the packaging process.
Usage is also very simple; just open, place in the carton or pallet, and seal.
The combination of easy storage and easy use present money-saving efficiency in the packing area. These efficiencies are being utilized by a host of today’s perishables shippers.
CooLiner provides thermal protection for any temperature-sensitive products, including pharmaceuticals, blood products, and perishable food items (such as dairy products, gourmet meal kits, ice cream, smoothies, baby food, and raw and frozen meat and poultry.)
