What’s the Best Lunch Bag that Keeps Food Cold?
The best lunch boxes to keep food cold come in myriad shapes, sizes, and colors, but have one thing in common: insulation! Add your logo, slogan, team name or special event to an insulated lunch bag and you enjoy daily exposure on a practical giveaway that’s sure to be appreciated when there’s a chilled lunch to look forward to. Read on for our recommendations.

What Does Insulated Lunch Bag Mean?
An insulated lunch bag is a bag designed to keep food and beverages at temperature longer. The bag can keep cold food and drinks cold or hot food and drinks hot. An insulated lunch bag is like a puffer coat for your lunch. And hopefully, the custom insulated lunch bags you choose to put your logo on are as eye-catching and on trend as the aforementioned puffer jacket as well. (We’ll show you our top picks for best lunch boxes to keep food cold and hot. Read on!)   

How Do Insulated Lunch Bags Work?
An insulated lunch bag is made of material that slows down heat transfer between the warmer air outside the bag and the cold air inside the bag. Similar to how a double-walled thermos or tumbler works,  custom insulated lunch bags feature additional layers or barriers between the air inside the container and air outside. The bag’s lining includes an internal interwoven foam material that slows the transfer of heat or cold. The denser the material, the better the insulation. Think of moving from Point A to Point B via a maze instead of a straight line. The crazier the maze, the longer it takes to get out!

Do Insulated Lunch Bags Need to Be Refrigerated?
Your custom insulated lunch bag delivers visibility for your small business at the office, on campus, on the field, and on the road. But does it need to be tucked away in the fridge in order to be effective? The short answer is no. An insulated lunch bag will keep food and beverage at temperature longer than a non-insulated bag, whether it’s stored in the fridge, in a backpack, or in a school locker. However, to maximize cold retention, it’s always a good idea to store your lunch bag in the refrigerator until you’re ready to snack. Another tip: Place your custom lunch bag in the freezer the night before you pack it. This way you’re placing cold food into an already-cold bag, buying even more chill time for your fresh lunch.
