CooLiner Insulated Envelopes

Easy to use, environmentally friendly and cost effective insulated envelopes.

Insulated Envelope CooLiner

CooLiner insulated pouches are lightweight thermal mailers designed for shipping flat or small-sized temperature-sensitive goods.

The thermal pouches can be quickly filled with your temperature-sensitive goods and sealed with an secure adhesive strip in a matter of seconds. Our insulated pouches provide the easiest method of shipping your small-sized items.

Made of recyclable #7* CooLiner material, these insulated bubble mailers are made using a combination of an internal bubble layer and a reflective outer layer which work together to provide reliable temperature control.

In the event the size of your payload exceeds the capacity of our thermal envelopes, our insulated box liners fill the need to ship “smaller than a pallet but bigger than an envelope” shipments with a guarantee that the temperature of the products being shipped remain largely unchanged throughout the cold-chain distribution system.

*May not be recyclable in your area

FAQs

What is CooLiner?

Made with a combination of metalized films and air bubbles, CooLiner material is an innovative type of insulated packaging that effectively protects shipments against extreme ambient temperatures.

Lined with a silver bubble wrap, these pouches give you all the flexibility you need. They are available in any custom size, and they can be filled and sealed in seconds.

Also available as a box liner, pallet cover or cargo blanket, CooLiner is recommended for protecting shipments for durations lasting 24 hours.

How does CooLiner work?

Our proprietary insulation technology, exclusively available at IPC, perfectly combines heat reflection and mass. In comparison to similar materials with a higher relative thickness, CooLiner provides superior temperature control.  It is the dual performance of the reflective outer layer and low thermal mass that allows CooLiner to outperform other similar products.

Reflective Foil Layer

The foil outer layer serves to prevent heat from radiating into the shipment. This works using the properties offered by this aluminized layer that allow it to receive and bounce away heat energy at a subatomic level.

Advanced Bubble Layer

With a unique structure carefully designed to inhibit conductive heat flow, CooLiner material can provide superior thermal protection to even thicker, heavier films.

The result of 11 years of research and development, our bubble insulation technology has, time and time again, proven to provide real-world efficacy.

Why is the CooLiner superior?

Unparalleled performance.  It provides a level of temperature control unparalleled in the industry.

Reduced operational costs.  CooLiner helps you to keep your work area efficient with quick and easy application. Another benefit is that CooLiner can be compactly folded away when not in use, providing valuable savings in warehousing and shipping.

Durable, puncture-proof and water-tight. CooLiner material is safeguarded against rips during transit, allowing you to rest assured your shipments will reach their destination without damage.
