Ideas

well, I think this could work, but I'm not sure how you'd sell it? What's your plan? I can see some benefit, but would it really sell?

Would it make tape weaker at the perforated points? Is that perhaps why it hasn't been done?

imagine if you try to unroll a large bit of tape, as if you're masking something for painting - the perforations will weaken the tape, and it will break where you don't want it. Submodified is completely right. Don't people think before they post hairbrained ideas?

sorry, i'm not quite a guru or anything. was just an idea. isn't that what this place is for?!

thanks to the constructive criticism to all who gave some. much appreciated

Hey, this is a great idea.

There is no problem making perforated tape, it is a common manufacturing process.

The limited stress would just limit it's application, find the right application and you should have an easy sell. This is probably whatever you were doing when you thought of the idea.

The strength would not be as weakened as you might think. Once an adhesive is attached to a substrate, the stresses are translated from tensile to shear. Basically all of the strain is on the glue, not the tape.

How will you determine the optimum distance between perforations?

3M market a product that is short pieces of tap in a rectangle canister. They even have one on a wrist band so that you can reach a strip while holding the poster with the hand that has the tap on it.

It would not be much weakened, good idea. Perhaps get a patent, and contact 3M or something

If that was a viable idea, 3M would have done it already. If there were perforations, the tape would rip even worse when trying to pull it off, as well as losing it's tensile strength for larger projects.
