I’m using manual capsule filling machine for supplements manufacturing.

The procedure is weighing the powder in the cup then empty it in the machine tray.
In this case, can we use any kind of plastic bottles during the production process so the powder gets in Contact with the plastic Bottles, is it allowed in the GMP? instead of using stainless steel cups?

Is there any reference available for allowing pvc use in pharma production?
