Black Tough Matte/Gloss Tape for Static Protection?

I noticed this tape covering a good amount of components in the motherboard. The thing is that i'm finishing up this old laptop restoration but the the original aforementioned tape definitely needs to be replaced. The laptop was disgusting full of tiny dead bugs and it's also stuck to the sticky side of the tape making it look like a scene from a Hellraiser movie. What tape is this, the sticky side is glossy while the other site is matte and the whole thing is very thick and hard. The bottom side of the motherboard has even more tape

Reminds me of "fish paper" which is widely used for insulation. Comes in various colors. May also come anti-static, but it is usually just for electrical insulation. Here's a link to a black version: https://www.digikey.com/product-detail/en/gc-electronics/560/560GC-ND/257752?utm_adgroup=Accessories&utm_source=google&utm_medium=cpc&utm_campaign=Shopping_Prototyping, Fabrication Products_NEW&utm_term=&utm_content=Accessories&gclid=EAIaIQobChMI-cq49ub26QIVr4VaBR2GlQc1EAQYAiABEgKQUvD_BwE

The sticky side could be an adhesive coating. More often what is have seen used was a double sided tape with no backing, sometimes known as adhesive transfer tape or "glue on a roll." (https://www.mcmaster.com/adhesive-transfer-tape )

What's the point of sticking that material over some motherboard components? Aren't the components in the mobo manufactured with built-in insulation?

With through hole components and metal cases, fish paper was used extensively to protect the bottom of the boards from contacting the case.

With more modern SMD boards, that is not such a problem, but one still might not want either the bottom or top to be in direct contact with the case. If you showed what was under the black "tape," the reason might be clearer.
