## Description

desertcart.com: Smilco 6 Pack Insulated Bags for Food, Thermal Box Liners, Reusable Waterproof Metalized Insulated Shipping Bags for Lunch & Shopping(13 x 8.5 x 12 Inches) : Industrial & Scientific

Review: Help keep food cold - I use these in my insulated lunch bag for traveling. They actually help so much to keep my food cold!
Review: Great for shipping sensitive items in summer heat - These were just what I needed to ship chocolates in 90° heat. I lined my normal shipping box with these, added a couple of ice packs, and shipped my items with no worries. These are great because in addition to keeping the items cool they also act as padding, eliminating the need for bubble wrap. The size was perfect, leaving extra space for folding the top over to keep the cold in and heat out.

- REUSABLE, SPACE-SAVING LINERS – Each liner weighs only 0.85 oz, folds flat to save storage space, opens in seconds, and replaces bulky foam coolers with flexible insulated box liners that wipe clean and can be reused again and again
- EVERYDAY FAMILY USE – From school lunches to takeout night, these foil thermal bags keep casseroles and takeout meals warm, and your salads or drinks cool while you’re on the go. Perfect for grocery runs, picnics, road trips, and weekly meal prep

## Questions & Answers

**Q: Can I use these to turn a bag into a lunch box?**
A: You can use it to wrap the lunch box to achieve the effect of insulation

**Q: Is it safe for food?**
A: Hello, it’s safe to use reusable insulated bags

**Q: Does it work with hot food?**
A: It will, up to a certain point. The inside is a soft Styrofoam/plastic and the outside mylar. I am sure that it will melt at a high enough temperature.

**Q: Do i put the ice packs inside the isolation or on top of it to keep items frozen?**
A: I generally put them in the middle.  I pack a lot of little refrigerated items, and my goal is to keep them cold, not frozen.  I have not received any negative feedback from my customers yet.  I don't know how well it would keep frozen items frozen.  But, if your question was to put the ice packs inside or outside of the thermal bag, well, you have to put the packs inside.  The whole purpose of the bag is to keep the outside temperature from getting in.

### ⭐⭐⭐⭐⭐ Help keep food cold
*by N***E on March 26, 2026*

I use these in my insulated lunch bag for traveling. They actually help so much to keep my food cold!

### ⭐⭐⭐⭐⭐ Great for shipping sensitive items in summer heat
*by R***E on June 26, 2025*

These were just what I needed to ship chocolates in 90° heat. I lined my normal shipping box with these, added a couple of ice packs, and shipped my items with no worries. These are great because in addition to keeping the items cool they also act as padding, eliminating the need for bubble wrap. The size was perfect, leaving extra space for folding the top over to keep the cold in and heat out.

### ⭐⭐⭐⭐ Used for a Cooler Hack
*by J***L on September 30, 2024*

I read in a camping and hiking fb group about a cooler hack and decided to give it a go. I was doing some primitive camping and needed my ice to last 5 days. The hack was to cut these bags, line your cooler with them and be sure to use one on the top of everything as well before closing the lid. WORKS LIKE A DREAM!!! Everything stayed very cold, even when the ice started to melt. The best part was I even came home with a small chunk of ice leftover. Since there were so many in this pack I did use two as storage bags and it kept food dry and cold. Grab these and try it yourself.
