PopupLiner Insulated Pouch

A high-performance insulated pouch perfect for small-sized shipments.

Insulated Pouch

The PopupLiner Insulated Pouch is our best-performing thermal mailer and is available in any custom size.

The self-inflating thermal envelopes arrive in patented large compression sleeves and inflate to full size when opened. These lightweight thermal mailers are constructed with a Mylar outer cover (an added benefit over non-reflective thermal mailers) and a high-performance polyurethane insulated panel.

This combination provides unmatched insulation, as well as excellent cushioning, shock and vibration protection.

Formerly known as GreenLiner, these thermal pouches could not be simpler to use. Simply fill them up with your temperature-sensitive goods, and seal it up with the peel-and-seal adhesive strip.
