Insulated Recycled Paper Liners for Cardboard Boxes
Line your shipping box to absorb condensation and maintain the temperature of your contents for up to 24 hours. These liners are best for small- and medium-sized shipments that would be damaged by heat, such as perishables and electronics. However, they’ll start to break down from prolonged exposure to water. Made of 100% recycled paper, they cushion fragile items just as well as bubble liners but without the waste of plastic. They are, however, bulkier than bubble liners, so they take up more space in your package. There are no special requirements for recycling these liners. Toss them in your recycling bin when you’re done.
To completely insulate your package, you’ll need two liners—one for around the top, side, and bottom, and another for around the other three sides. These liners are easy to cut down if you need to customize the size.
R-value measures the liner’s ability to slow heat flow. The higher the value, the better it insulates. A value of 5.1 means these liners maintain temperatures between 32° and 90° F for short periods.
