How about a large ziplock bag inside a large ziplock bag inside a large ziploc bag? Just leave the innermost bag just slightly open and have the open ends on opposite ends. Once the air is sucked out, you should be able to close the innermost bag without releasing suction. Another option would be to put a couple of nested ziplock bags in a much larger space bag. With the ziplocks as far away from the suction valve as possible, you should get minimal material escaping and getting sucked into the vacuum. -- Nathan, TX -- Hire the lazy man.

Worked with silica fillers for decades. Highly doubt you will be successful reducing the volume significantly? Colloidal silica is micro powder. The size ranges in commercially available fillers are measured in sub-micron to ~100 microns. It will be very hard to filter material out of any vacuum system to reduce the volume for shipping.

Hi John, You may want to check if sending thickener by the post or UPS might violate shipping hazardous materials. I would consider that as hazardous as asbestos fibers. The GG1 project is still ongoing. I work slow so as not to make any big mistakes. |

A chamber vac will work since the pressure inside and outside the bag remains equal during sealing, there is no tendency for the material to move. You can even seal up a bag of water with one. -- Half of what we read or hear about finishing is right. We just don’t know which half! — Bob Flexner |
