The key to keeping your content silent is slight compression packed as per instructions there is no rattling.
It’s recommended to use rolled Plastic Lunchwrap, Bubblewrap, Cloth or Latex Gloves to take up any unwanted space inside the Aeroclam.
As seen here, the LunchWrap over the top of content prevents the content connecting and nullifies any rattling.
You can of course load whatever you require into the Aeroclams but make sure any unwanted space is taken up by the above.
Should you have any further questions, please don't hesitate to contact Pat via email email@example.com. Thank you!
