Insulated Bubble Shipping Box Liners

For leak-free insulation, line your cardboard box with these plastic liners. These liners maintain the temperature of your shipment for up to 24 hours, making them ideal for shipments that would be damaged by heat, like perishables or electronics. Padded in bubble wrap, they protect your shipment without the bulk of paper liners or insulated foam. An adhesive strip for sealing prevents condensation or vapor from leaking outside the liner.

Insulated Recycled Paper Shipping Box Liners

Two Liners

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.

Insulation R Value—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.

EMI/RFI-Shielding Cardboard Shipping Boxes

Safely ship circuit boards and other sensitive electronics with two layers of defense against EMI and RFI signals. These boxes have an outer conductive layer that shields your box’s items from electrical noise outside the box, preventing malfunctioning. The inner conductive foam lining dissipates charges inside the box created by handling or movement. The foam also creates a cushion for your items. All meet ANSI/ESD standards for controlling electrostatic discharge and packaging sensitive electronic components.
