Having trouble figuring out what product category this falls into

What would you put this product under- just going off these basics:

Food-contact

Food-processing aid

Not consumed

Not packaging

Non-additive

Disposed of after use

Facility only produces this product.

Different experts have said different things (FSSC category I, to K, to not applicable to anything)

Curious to any thoughts, thank you!

Not to into wasting time, what is the item?

Specify the product first.

If you want to put this material into contact with food, you'd better apply category C so food safety is always implemented.

It might look like category K is applicable, but it wouldn't guarantee food safety.
