From an FDA perspective, the material-qualification requirements for pharma packaging/administration systems are based on a separate regulatory section than the biocompatibility requirements for devices. Within the FDA's regulatory scope, there also is a third material-qualification basis, for food packaging.
Qualification of a material per one of these three regulatory bases, does not qualify it for either of the others. The systems are independent, and the tests are not substitutable.
In past years, this was less clearly defined. Back in the late 70s, for instance, evidence that a plastic material to be used in a device was Class VI qualified (which at that time was just a certificate from the resin vendor saying that it was not contaminated, basically) plus maybe a Draize test was all that was needed to establish biocompatibility for a 510(k), even for an invasive device.
I don't have the specific 21CFR sections immediately at hand for requirements for pharma-packaging/administration systems and food packaging. If someone else doesn't post them first, I'll try to post them here later today.
