The indication of the thickness of the text of "3 mm" is completely wrong. It should read 3 mil! The word "mil" (therefore initially 1 mil) refers to the measurement unit in inches by 2.54 cm (1 inch = / inch), divided by 1000 times 3 = 80 microns (76.2 exactly) or 0.08 mm as standard value within the film details. At 5 mil corresponding turn 125 microns (127 exactly) or 0.125 mm as standard value within the film details. Mil is actually local standards a relatively unknown measure, therefore, to facilitate the conversion description. The one who has described the product, thought probably to mm as he read the word "mil", but obviously knew probably not correct. ("To err is human," said the hedgehog, and rose from the wire brush.)
For a product under the laminators (initially only have a take a close look) is also read that it can process 5 mm thick films. This is also completely wrong, because strengths of half a cm would damage almost any standard laminators. For this purpose, none of these devices is designed. ;-)
Note: if the film actually 3 mm thick, would then have the package at 100 pieces incl repackaging already higher than 30 cm be.. This is definitely not the case!
