Frequently Asked Questions about Thermal Mailers
Starting out with insulated mailers? Have a look at some of our most frequently asked questions about insulated mailers and thermal pouches.
What are insulated mailers used for?
Insulated mailers are used to ship temperature-sensitive goods such as frozen foods, meal kits, pharmaceuticals, and lab samples. Their lightweight, compact design helps protect products from heat exposure and temperature fluctuations during short- to mid-range transit.
Can insulated mailers keep items frozen?
Yes, when paired with dry ice, Insulated Product Corp’s insulated mailers can help maintain frozen temperatures, depending on shipment duration and climate conditions. For longer shipping durations, we recommend frozen shipping boxes. Insulated pouches are a great choice for 24-48 hour shipping of temperature-sensitive food, like cold shipping chocolates, vaccines, or biotech samples.
Are your thermal mailers recyclable?
IPC offers several recyclable options, including CelluLiner, a curbside-recyclable insulated box liner and EcoLiner, made of recycled denim insulation. These sustainable pouches reduce landfill waste and meet corporate sustainability goals without sacrificing performance.
How long do insulated pouches maintain temperature in transit?
Our thermal pouches are engineered to maintain temperature ranges for up to 48 hours when used with appropriate refrigerants. Actual performance depends on outside temperature, product load, and insulated mailer type.
What size insulated mailers do you offer?
IPC manufactures a wide range of stock and custom insulated mailer sizes, from small 6×6” pouches to oversized options, 9″ x12″, insulated packaging for meal kits and bulkier products. We also provide custom sizing for wholesale insulated packaging purchases.
What is IPC's minimum purchase quantity of insulated thermal mailers?
Minimum order quantities vary by product type. For most stock sizes, IPC offers pallet-based minimums, while custom configurations may require a higher volume.
What are the best insulated mailers for pharmaceuticals?
For pharmaceutical shipping, IPC recommends our PopupLiner thermal pouches or CelluLiner recyclable mailers, which provide high thermal performance and compact packaging.
