Color: Pack of 4


Features

  • Protective Foam Bags for Valuables: The expanding foam bags are widely used for the transportation of valuable items such as computer hosts, fragile ceramics, parts, equipment, etc., effectively protecting items from occasional collisions and vibrations.
  • Size Introductions: The package contains 4 pieces of quick expanding foam bags. Each bag measures 16" x 14", and it is recommended to use a box size of 8" x 8" x 8". Each packing foam bag is individually packaged. Compared with traditional bubble wrap, our packing foam is smaller and easier to carry, takes up less space, and is convenient for storage.
  • Easy to Operation: 1. Squeeze liquids in Zones "A" and "B" to thoroughly mix. 2.Once liquid seeps out, evenly distribute it throughout all voids inside the bag quickly. 3. For PC: Place bag into computer case, cover with lid, allow it to expand fully. For boxes: Place bag into shipping box with items, secure bag, wait for full expansion.
  • Friendly Reminder: The foam bag expands rapidly. Upon hearing a "pop" sound, please promptly distribute the liquid evenly and place it in the space. If it is a large box or a large computer chassis, you may need to use two foam bags. Once fully expanded, it will fill the space and conform to your items, so please place your items during the expansion process.
  • Efficient Equipment Protection: This cost-effective expanding foam bag allows you to transport your equipment without dismantling its components, significantly reducing the risk of damage caused by collisions and vibrations during transit, thus saving time and enhancing efficiency. If you encounter any issues during use, please feel free to contact us via email.

  • TECHNIQUE. TECHNIQUE.
Size: #10 16" x 14" Color: Pack of 8
Just like SpongeBob said to Squidward: TECHNIQUE. WEAR SAFETY GLASSES AND BE AWARE OF SHARP OBJECTS. If you read the directions on the packs and follow it verbatim you may not get the best results. See my photo. First pack on the right, barely inflated. Second time I really pushed and mixed up the Part A and B back and forth (step 4 on the pack instructions) it worked flawlessly and quadrupled the foam expansion. TLDR; follow the steps but on step 4 really mush/push the two agents back and forth to mix them together. Once it pops and shoots into the main bag spread it out and work fast. ... show more

  • Akin to the packing in a prebuilt PC tower. Simple to use and effective.
Size: #10 16" x 14" Color: Pack of 8
I recently used these to ship an assembled desktop PC without issue. Use is not difficult. Simply follow the directions. Some force is required to rupture the internal seal between the two reactants to produce the foam, then one must work quickly. The outer bag tore on one foam pack, causing the foam to leak, but this was not a huge issue as that one was used to cushion the outside of the tower and I faced the leak away from the case so the foam only touched the cardboard. When solidified, they provide excellent protection to the item. ... show more

  • You may get a good order or you may not.
Size: #10 16" x 14" Color: Pack of 16
My first order was great, but my second order had defective bags in it. I haven't used all the bags in the second order but I already had one that didn't inflate and several that didn't work well.

  • Really great for packing pcs
Size: #10 16" x 14" Color: Pack of 8
A little tricky at first due to having to press down continuously on the left side before finally getting the initial pop, once you get past that first hurdle the rest of the process is pretty smooth. Once you mix the two sides together you have to be quick to spread the inner foam and stuff it into place so that it fills in nicely, but once you get the hang of it it's perfect for packing and shipping pcs. ... show more
