I'd think welded PVC would be a better choice. How is the box being closed?
As long as it isn't a leak hazard... as that what the issue with the baggies were; they came loose and when hit by a robot spilled EVERYWHERE... My memory is no good but IIRC a red card was handed out for the incident, due to the downtime needed to clean up the mess on the floor (you can imagine the sound created by the vacuum, high speed pinging!) and also because the baggies were supposedly deliberately "hidden" from the robot inspectors who would have otherwise not passed the ballast as legal.
Same goes for sand and any other "granulated" ballast weights. Make sure it is sealed and well attached.
