FAQ

Insulated Cooler Bag FAQs

How long do insulated bags keep food hot or cold?
With standard 3 mm EPE foam plus reflective aluminum foil lining, contents stay within about 10°C of packing temperature for 4-6 hours. Upgrading to 5 mm foam extends retention to 8 hours and beyond.
Are the insulated bags leak-proof?
Yes. Inner seams are heat-sealed, so melted ice, condensation and sauce spills stay inside the bag. For liquid-heavy loads we add a welded PEVA inner liner.
Can you print my logo on insulated bags?
Yes. We print with silk-screen or heat transfer on the outer fabric, from one-color logos to full-color photographic artwork. If finished artwork is unavailable, a paid design service can be quoted separately.
