and is causing these crazy patterns of sticking
I'm not an expert with plastics, but your use of the word "crazy" reminded me of a phenomemon called "crazing" which is is cracking of materials (plastics & ceramics mostly) into patterns that could resemble "lightning". Sometimes it goes all the way throuhg a material; sometimes just the surface. Typically it is caused by thermal, mechanical or chemical stress.
If the problem is just patterns in the adhesion of the materials, then crazing probably isn't related.
A quick web search found
"A major electronics equipment and computer manufacturer first encountered the polycarbonate compatibility problem with dissipative polymers. Their field service people noticed that polycarbonate-containing components were "crazed" which then cracked when used. Later, they found another crazing problem that was time related and was traced back to their static dissipative shipping and storage bags. This second polycarbonate compatibility problem became critical when a costly worldwide product recall was required to replace the crazed parts.
In general, polycarbonates can be seen as polar, rigid thermoplastics. As expected with chemistry's "like dissolves like" rule, a polar solvent or molecule with a polar end will try to dissolve into the polycarbonate surface. However, because polycarbonate is rigid, it cannot expand or swell to accommodate the solvent. It accommodates the solvent molecule by surface cracking or crazing at a stress point, which leads to further surface attack and ultimately breaks in two."
Don't know if that is at all related, but it might give an idea or two.
