Need to pay attention to the difference in thickness unit between PET release film and PET film-film supplier

PET release film and PET film are commonly used materials in electronics, adhesives, die-cutting, packaging and other industries. Due to the different industry sectors, the companies on the market also call various thicknesses differently, and the differences in units lead to confusion in the names of various specifications. Therefore, we must understand the commonly used thickness units of PET film and PET release film to avoid sending The samples delivered are inconsistent with the samples required by the customer. Commonly used units for market chiefs are as follows: 1mmu003d100c (silk)u003d1000um. Among them, the unit c (silk) is not a national standard unit, and is more common in the hardware machinery industry. There are also individual companies that use 'bars' as the unit, 1 bar u003d 1c. Zhonglian is here to show examples of commonly used thicknesses. The usual thickness of PET film has the following specifications: 0.012mm, 0.025mm, 0.036mm, 0.05mm, 0.075mm, 0.1mm, 0.125mm, 0.15mm, 0.175mm, 0.188mm, 0.25mm. The thickness of the PET release film is actually divided according to the thickness of the PET film. When ordering or consulting, you must clarify the units you usually use. Some companies are accustomed to using mm, some companies are accustomed to using c, and some companies are accustomed to using micron. The most common mistake is to make a mistake in ordering 0.025mm and 0.25mm, 0.025mmu003d2.5cu003d25um, 0.25mmu003d25cu003d250um. I believe that many companies have encountered this situation, the demand is 25 thickness, and then the samples received are far from their own needs. This is caused by unclear unit differences.
