How to Make an Insulated Lunch Bag

Making your own insulated lunch bag is a great way to save money while helping the environment. This project is easy to do and only requires a few supplies.

You will need:

  • Outer fabric of choice
  • Insulated fleece
  • Spray adhesive
  • Sewing machine
  • Trimming scissors
  • Velcro or other closure
  1. Cut two pieces of your desired lunch bag template out of both your outer fabric of choice and the insulated fleece.
  2. Use a spray adhesive to glue the insulated fleece to the backside of the outer fabric.
  3. Sew the pieces together. Quilting the fabrics is also suggested as it will keep the pieces together and create a sturdier bag.
  4. To finish the bag, attach Velcro or another closure of your choice.

You can find many great lunch box templates online. To keep food cold, put an ice pack in the bottom of the bag and pack your lunch on top of it. For hot lunches, put the food in a thermos or microwaveable container and heat it up before packing it.


Insulated lunch bags are an eco-friendly switch to plastic and other disposable bags. They reduce waste, save money, and let you put a stylish twist on lunch. You can even make your own with some fabric, a sewing machine, and a little bit of creativity.
