Quick Expanding Foam Packaging Bag
Quick expanding foam bags are usually compressed before activation, so they have a small volume, which is one of their greatest advantages. Due to their small size, these foam bags are easy to carry and store. You can easily place them in your garage, warehouse, or toolbox for future use. Umail’s quick Expanding Foam bag is widely used in protecting fragile items during transportation and storage, such as electronics, moving a PC, glassware, ceramics, and other fragile items. Using quick expanding foam bags can reduce waste and the burden of cleaning work and protect the quality of items.
How to Use Umail’s Expanding Foam Bags？Easy to Use, Professional Experience
Step1 ：Activate the Foam Bag
Fully unfold the foam bag on a flat desk or surface. Press firmly on the“L”symbol to activate the foam. You will hear a small popping sound as the foam begins to expand. Mix the components of the foam by firmly patting back and forth between the “L” and“R” symbols. do this 15-25 times within 8 seconds to ensure that the foam is evenly distributed and fully activated. After finish tapping, quickly spread the liquid to every corner of the bag to ensure it fills the bag completely.
Step2：Put Expanding Foam into Box
Quickly place the bag into the box, then quickly place the item onto the foam bag, apply moderate pressure to help the foam bag completely wrap around the item and take its shape.
Step3： Repeat to Create Another Foam Bag
Make sure that the foam is in contact with all surfaces of item including the corners and edges. Lastly, Close the box and seal it with tape.

SHIPPING PC
According to our experience, when using the expanding foam bag to protect your computer, you should place it in the computer case as soon as the bag starts to expand. The bag will automatically adapt to the shape of the computer inside, providing protection. Do not wait until the bag has expanded significantly before inserting it into the computer case, as the metal of the case may cut into the already expanded bag when forcefully stuffing it in. Also, you should not forcefully stuffing 2 bags at the same time as the pc case is not enough. If it is really necessary to use 2 bags, please wait until the first bag is completed before putting in the second one.

I bought these ready to ship a small ITX system... and didn't realize just how thin that bag wall is. as it expanded the bag popped and turned a REALLY nice system into a 400 usd mistake. I won't be buying some of these and if you do find a smaller size this is just too cheaply made.

Was bought to stuff a computer for safe traveling the same way its used in one of the photos on the advertisement and instead it completely blew up and spread the foam all over the room and inside the computer. Completely damaging the inside of the pc as the foam leaves a residue and the impact of the bag exploding.Now my computer has to be replaced!!

This product does not perform like the product photos show. The foam expands the bag to approximately 1 inch thickness, which is a far cry from what the product photos showed.

Works exactly as I remember when we used to use it on an industrial scale for packaging odd shaped products. When you crack the first pouch it immediately comes in contact with the reactive material in the 2nd pouch. You have just a few seconds to thoroughly mix the two before the end product bursts through a membrane and fills the envelope. Work really fast, mix, knead, squish completely (corners too). Be ready to use it as soon as it starts expanding because at that point, mixed is OVER. I had no problem and it performed exactly as I knew it would. Thanks

This product worked as described in the instructions. Make sure you have everything ready because you only get one shot at it. One small disappointment was that the expanding foam did not completely fill one of the two bags I used. But it conformed to the odd shape of the item I was shipping and held it firmly in the shipping box. So, all-in-all very good. I will use these again in the future.
