Smilco Reusable Insulation Bags Thermal Box Liners Metalized Box Liners Lunch Food Shopping Bag Insulated Lining Waterproof Insulation Package (20 Pack/ 11 In x 15 In)

Great product. Very helpful. Very functional. As advertised.

Lightweight, reusable, and do exactly what they promise. The metalized lining holds temperature well for groceries or lunch boxes, and they fold flat when not in use. Not fancy, but practical, durable, and worth it if you need reliable thermal insulation.

Edit: It works with ice packs and an insulated shopping bag. If you use it together- it works PERFECTLY! 5 stars. Leaving old edit for chemical smell. Because after a while it goes away. So just noting be aware. However it works great. Giving 3 stars for item arriving on time. I needed these urgently but couldn’t get options for delivery to arrive in 2 days except this item. The item came nicely packed. However they are very thin as in,1/8 inches and smaller than the size listed 13” by 15”. They are more likely mail envelopes. I hope it will keep food cold for packaging. Also note they have a bit of a weird chemical smell.

Basically paper inside with foam liner and a foil outside, so the inside surface easily absorbs any spills and cannot be washed or rinsed off so has to be discarded. So reusable to a point. But for the price, can't complain.

Great quality

Works well with packaging

The insulation bags are flexible, reflective, with thermal insulation outside and inside, they seem to work pretty well keeping cold chocolate chips from getting soft.

I thought the bags were large enough to fit a round 8 or 9 inch two layer cake. Unfortunately it’s not. The bags nice but again, unfortunately, way to small for what I need them for. These seem to be the largest ones I see on Amazon. I’ll try to find larger ones in a store near me.
