8 Pcs 14”x16” Expanding Foam Packaging for Irregular-Shaped Items - Shockproof Expandable Packing Foam, Protective Computer Shipping Material for Electronics & Fragile Devices

If you have fragile misshapen items that you need to store or ship you DEFINITELY NEED these Umail self expanding foam packaging bags! These are completely self contained self foam inflating bags that form fit to anything thus providing a custom shaped foam pad instantly. First off as i mentioned above these are completely self contained, as each individually sealed packet is one self foam filling packaging bag thing.. Once you open the clear packaging you want to unfold and spread out the umail protective bag thing and inspect that there are no tears or holes since this bag keeps the liquid foam from attaching to your items during foam creation / inflation. Inside the bag there is a rectangular bag that is where the chemicals get mixed, within this there is two square bags that you pop to begin the process. If needed the instructions are printed on the bag for quick reference and offer two options for activation. Now it's extremely important that you don't activate the foam creation and inflation until you have everything in front of you and are ready, as once you start you have a very short amount of time before the foam becomes more solid with a consistency of a styrofoam cup. As such once you activate and mix it will rapidly expand and pop the mixing bag at this point you very quickly place the bag in the box and spread it out. After that you want to place your item and lightly press it into the expanding foam. Within a few seconds the foam will solidify and create a custom mold around your item, this will give it the very best protection as even small parts are encased. Now it is worth mentioning that the chemicals when mixed create a fair exothermic reaction (it will get fairly hot) this is short lived and stops as the foam solidifies. I mention this as if your item is sensitive to heat you should be aware of this fact. Beyond that however, once in its solid state the foam will insulate your items extremely well and can be utilized in conjunction with chemical warners or cooling product

• PERFECT PACKING SOLUTION: Umail’s expanding foam for shipping are used to use on an industrial scale for packaging odd shaped products, or oddly shaped items, meters, vases, crafts, and even a fully built PC with GPU installed, pc packing foam. They are great for shipping fragile items.WORK QUICKLY: When you crack “L” symbol it immediately comes in contact with the reactant in the “R” symbol. You have only a few seconds to thoroughly combine the two before the final product bursts through a membrane and fills the envelope, so it's super important that you don't start making the foam and expanding it until you have all the supplies you need right there and you're ready to go. Once you get started, you've only got a short amount of time before the foam hardens up and feels like a Styrofoam cup.EASY TO USE: Place foam bag on desk, crack “L”, you will hear “peng” sound, then slap “L” and “R” with both hands quickly. Pat 20-25 times within 8 seconds. Then wait for liquid expand and break through L/R area, and quickly distribute liquid evenly throughout bag. Note: Only simple spreading to all corners of the bag is required here (e.g., follow the video instructions), do not keep spreading, as it will disrupt the foaming process. Once you've done that, you should position your item and gently push it into the expanding foam. In just a few seconds, the foam will harden and form a bespoke mold around your object, providing optimal protection as it envelops even the tiniest componentsWHAT YOU WILL GET: 8 pcs individually packaged expanding foam packaging bags. We recommend used for box size of 8"x8"x8". Please note that the heat generated when slapping the pc shipping foam bag is normal and it will soon return to room temperature, just like holding a hot cup of coffee.WATCH TUTORIAL: If first time user, watching tutorial or instructional video at listing to get a better understanding of how foam expands and how to apply it properly. This will help ensure a good results and prevent expandable foam from expanding more than intended. SHIPPING PC: According to experience, when using expanding foam for pc shipping, please place it in case as soon as bag starts to expand. It will automatically adapt to the shape of computer, providing protection, not wait until bag expanded significantly. Be careful to avoid sharp objects. When shipping a desktop computer, place one expending foam bag inside the computer case and one on each side of the chassis. This protects sensitive components and ensures the computer arrives in perfect condition.
