## Description

Product description 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 about 25 times quickly to ensure that the foam is evenly distributed and fully activated. After finish tapping, quickly spread the liquid to every corner of the bag. Note: Only simple spreading the liquid to all corners of the bag is required here (e.g., follow the video instructions). If you keep spreading during the foaming process, it will disrupt the progression, causing an unsmooth foaming reaction and insufficient expansion. 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. Further Enhance the Product Protection You can trust Umail’s expandable foam packing to protect your valuable items. Our foam material provides excellent cushioning protection, strong enough to prevent damage during shipping and storage. 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. Tips for use If the foam doesn’t cover the entire bag, it could be because you didn’t spread the liquid evenly throughout the bag. You should try patting the bag quickly about 25 times as quicky as you can. This will help distribute the liquid evenly and ensure full coverage. Additionally, make sure to keep the bag flat and avoid overfilling to prevent the foam from spilling out. It’s also important to follow the manufacturer’s instructions carefully and use the recommended bag size. If you’re still having trouble getting full coverage, consider using a different size bag or foam product that is designed to provide better coverage. Before using Umail’s expanding foam pack, make sure you have a clear idea of where you want the packing foam to expand and how much you will need to use. This will help you avoid overfilling and wasting shipping foam. Watch a tutorial: We provide tutorial at page, if it’s your first time using the expanding foam packaging, consider watching a tutorial or instructional video online to get a better sense of how much the foam will expand and how to apply it properly. This will help ensure that you get the best results and that the expandable foam doesn’t expand more than you intended.

Review: Good - Shipped fast, it worked as intended to pack fragile item (glass). You have to lay the bag flat on the floor, press the Left side until you hear/ feel a pop, then press right and left (marked area) back and forth to mix throughly. The mixture will then explode inside the bag and u have to spread it evenly quickly, then place in box to harden, after spreading it out evenly I placed it in the box and closed the box and held it down until I felt it was hardened enough so it fills up the box and did the other side same way. You should have everything ready to go as you have to work quickly!
Review: Best Packing Material I've Used - This is a great packing material to protect an item for shipping. The expanding foam forms to the item to protect it during shipping. I used one on the bottom holding my item down in the foam as it expands. Then when the foam is set I used another one which I laid on top and closed the box lids and held them down to make the foam form around my item. After a few minutes you're done. Unfold the lid remove your foam and check out what you did. Perfect, my item wasn't moving anywhere, it was locked in foam all around. One TIP: pre-plan what you're going to do. Once you break the pouches and mix up the foam (per instructions) you need to move quickly as once it starts expanding you don't have much time. This stuff is perfect. That's the way to ship anything you don't want bouncing around during the rigors of shipping.
