Securing usual complimentary items in cabin
 

Could anyone give some input (suppliers would be very useful) of methods you use to secure cabin items such as confectionary, catering, etc... in the cabin. Preferably securable via a seatbelt on the bench seat. Aircraft is a mix of lightweight/super-lightweight.

Any manufacturers who make a commercial solution that can be branded would be excellent.

PM if it's more convenient. Thanks
