22 x 27 Inches #80 Instapak Quick Room Temperature Bags, 24 Bags (E-2032-24)

Work fine but if your first user, let me tell you it expanded very very fast so if it your time using it just note to self to have everything ready.

I really like this product. Works perfectly. I will buy this product again. Also, I wish I can buy one bigger than 22" X 27".

These things are great for packing those oddly shaped things you need to ship. All that you need to do is take it out of the wrapper, unroll it, break the pouch of liquid by pressing down until you here the pop, and then you have about 3 seconds before the foam starts expanding. These are a lot better than packing peanuts. Some helpful tips I found: - Make sure you have your box read to go, as these things expand fast. - Once you get a hang of activating the foam, I like to unroll the pouch around the item I'm shipping before I activate it so I don't have to quickly put it in place - These things get hot. You have only about 15 seconds from activation to manipulate the bag before it gets too hot to touch. The one thing I'm not a fan of is that these are not recyclable. You can mail the inflated foam to recyclers around the world, but that doesn't seem economical. In terms of environmental impact, I'll stick with bubble wrap.

A really great idea - these ship rolled up, and you can fit around 5 or 6 in a small shipping box. You unroll it, lay it flat on a surface, press hard on both pressure points to break the chemicals and start to mix them - then the bag starts to fill with foam. It's really quite amazing, but a few things worth noting: 1) The bag gets extremely hot when you release the chemicals and it starts filling with foam -- so much so that there are steam vents on the top of the bag. If you were holding the bag in your hand it could burn you - that's how hot this gets. 2) 3 out of the 6 bags I ordered didn't fill completely with foam - slightly disappointing given the high cost of each bad 3) You have about 15 seconds before the bag fully hardens, so you have to quickly wedge it into the box you're shippingha. After than, the die is cast and the foam becomes hardened and is no longer malleable

I used this packing material to protect my PC from shipping it from Virginia to Florida. it did its job but it was a little bit of a tight fit and was worried it would break something. But it removed fine and all my components were good. worth the investment if you have a high end gaming PC that you need to transport.

i hate shipping computers. but i had to. so i used this product. once you mix the pouch. you must move QUICKLY...... this product is awesome.

I don't write many reviews. I feel the need to for this product. These are very high priced when buying individually. The instructions are clear enough but the product doesn't work very well. You put them down on a flat surface and 'pop' the A side of the chemical vial. Then you mix the two sides together until they build up enough pressure to pop the outer container and send the foam into the bag. Here's the rub. It does not fill the bag evenly. You can help it along but you have precious little time to do so. You then have to place it in the box and the item on the foam before it cures and hardens. I bought two of these for one shipping package. I put one in the bottom and one on the top. By the time I got the first one in the bottom , I realized it had not expanded evenly, so one side of the box has no foam at all. The second one went a little better as I evened out the foam as it was filling the bag. Still though, it didn't get across the whole bag and one side had very little foam. At close to 10 bucks a piece, I don't feel these were any better than peanuts or bubble wrap. I could have gotten more even cushioning from the peanuts or bubble wrap at a lot lower price. I had no issues with the heat. They were warm but not super hot. Maybe if you were using a lot of these you would get better at it, but I would not suggest them for a one time deal. I will not buy these again.

A bit big for a mid tower case but worked wonderfully.
