Now that we are all concerned about what may be hidden in our mail, how about some of the film processors who read this publication developing clear plastic envelopes? That way you could sort of see what is inside.
It may be possible to incorporate an antimicrobial agent into the film. I am a mold maker for injection molded plastics, and not familiar with film applications, or I would do it myself.
I occasionally peruse office supply catalogs and have never seen a similar product available. I bet you could sell them now. Maybe plastics can make it possible to help protect our security.
