Can a big bag be connected dust-proof?

A Big Bag can be connected dust-tight by means of a clamping adapter. For a Big Bag with a spout, this can be done with an inflatable bellows, for example. The bellows compresses all the wrinkles from the trunk, so that the cracks remain closed. The inflation cuff follows the irregularities and cracks of the Big Bag. Another possible solution for a Big Bag with a spout is a clamp with a foam seal that can absorb the irregularities of the Big Bag.

For a Big Bag without a spout, it is more complicated to create a good dust-proof connection. It is possible to lower a Big Bag without an outlet hose into a product hopper with a knife with all-round seal in combination with an extraction.
