Review on SPR60041 Sparco Heavyweight Package Sealing by Brock Chisholm

We are a machine shop specializing in the precision machining of components. Some of our parts are quite heavy. This adhesive tape has proven to be a very good alternative to the much more expensive 3M version. That's all we use. Goes further without much effort to prevent wrinkles. It's crystal clear. It's 0.003 inches (0.076mm) thick (not sure how many "mils" that's equivalent to - we're a machine shop, after all, so we measure things in specific units, not an industry standard).
