Most crime scene tape is non adhesive you could always tape it with some other tape. There is some evidence tape here that is adhesive that is used for sealing boxes. http://www.amazon.com/gp/search?ie=UTF8&...

Yes. It's called 'caution tape'. At hardware stores.

I'm looking for novelty tape modeled after the black and yellow police tape that says "crime scene do not enter" with adhesive backing, because I want to decorate my door frame with it. So far I haven't had any luck finding one with an adhesive backing to it, so if anybody knows if it exists, or anything similar, such as biohazard, quarantine, etc. I'd greatly appreciate being pointed in the right direction, thank you and have a nice day!
