Classically, Peter Parker designed his webbing so that it would dissolve after an hour or so, but before then would be stronger than steel. This was done so that cops arriving on the scene could arrest the evil-doer and put them away. It additionally made it impossible for someone to collect a sample and analyze it in a lab unless they were really quick.

Raimi’s Spider-Man, however, naturally produces his own webbing. I am not a biologist or a zoologist, only a humble chemist, but I’m pretty certain that spider webs in nature do not naturally dissolve away within a day or more. Given that, I would think that this might cause difficulty in arrests. Did his webs dissolve in the trilogy, or are there pieces of webbing hanging in the wind attached to buildings all over Manhattan?
