ChargePoint Technology sell "ChargeBag Clip"

This product retention seal for flexible packaging is a simple clip that keeps product safely contained within the packaging during dispensing and transfer. It can be used alongside a ChargeBag and/or ChargePoint valve, for example to hold powder in place while coupling a ChargePoint valve to a ChargeBag, while connecting or disconnecting an open ChargeBag from process equipment, until the ChargePoint valve is opened for transfer, or across an empty ChargeBag while its valve is uncoupled for cleaning, preventing bulk powder release.
