Sealed Air Instapak Quick RT, #80 Bag for 18"x12"x12" Box, Easy to Use, The ultimate protection for fragile shipments, Foam Packaging Bags (Pack of 24), Light Blue (13173)

Work as advertised, and a good price too. Invaluable when packing heavy or delicate items.Be sure to get the right size for the boxes you are using.

I use Quick RT all the time.The batch I received has issues. The bags blow inside the box and foam spills out all over the contents. 4 bags in a row, same problem.

I use these frequently to secure heavy objects inside a moon for shipping.

These are great! makes shipping our product way simpler. They nestle everything securely and we have not had a problem to date of damage.They are a little expansive but super easy to use. Will definitely order again!

Ever wonder how they make those custom foam packs? Wonder no more!These bags are very handy for packing items that are fragile and need a custom-formed mold. We use them, along with some flat foam, to make a carrying cases for a specialized computer equipment inside an ordinary hard shell suitcase.(The poor man's version of a Pelican case.)You lay the bag flat on the floor or table , and then at the bottom of the bag, there are two foam catalyst sacks labeled A & B that you can feel.. You push down on the A side and it will squirt the contents of the A sack into the B sack inside the bag. You then keep going back and forth for a few seconds to mix it and the foam catalyst bags will begin to expand into the rest of the bag. You have to work quickly to spread out the foam inside the bag. It feels quite warm. You then quickly place the bag in or around the item you are packing and hold it there. It is hard in less than a minute.We found then very effective.The company would sell alot more of these if you could buy them in 10 packs rather than an entire case.See https://www.youtube.com/watch?v=4K8Q1uLKI7U for a demo on how they work and how much they will expand.You typically want to buy it bigger than the container dimensionsThe video shows a bag pre-warmer but we did not find this necessary as long as your office is at room temperature.

Worked as advertised, you need to work fast when using them and know exactly how you want to pack you piece. They expand and set fast.

Product was just as described. It didn't come in original packaging box but it's all good.

Ive used these for years in my small business. They work great but no matter who you buy them from, they are spendy.
