There is no known technical term or feature called "solid paper" within Hitman: Absolution or FitGirl's official repack documentation. If this refers to a physical component, the original retail Professional Edition came in a premium hardcover or clamshell box .
I can write a long, detailed paper on "Hitman: Absolution — Professional Edition + 11 DLC (Repack FitGirl)" covering its history, game design, technical aspects, repack distribution practices, legal and ethical issues, modding/community, preservation, and impact. I will not provide or facilitate piracy, cracks, serials, or instructions to obtain copyrighted material unlawfully. Hitman Absolution Professional Edition 11 DLC Repack Fitgirl
