PET release film is a commonly used material in industries such as electronics, adhesive, die-cutting, and packaging. However, due to different industry fields, the names of various thicknesses on the market are also different, and the differences in units also lead to confusion in the names of various specifications. To avoid confusion, the commonly used thickness units for PET films are listed one by one, hoping to be helpful to everyone.

To distinguish the thickness, the first step is to understand the commonly used thickness units for PET release films. Currently, there are several commonly used types on the market: 1mm=100c (wire)=1000um, which means that one wire is equal to 10 microns. It should be noted that the unit of c (silk) is not an official national standard unit and is commonly seen in the hardware and machinery industry. In addition, some enterprises use "strip" as the unit, with 1 strip=1c, which means 1 strip is also equal to 10 micrometers. The commonly used thickness specifications for PET films are 0.012mm, 0.025mm, 0.036mm, 0.05mm, 0.075mm, 0.1mm.0.125mm, with a maximum thickness of 0.25mm

The thickness division is generally based on the thickness of PET film, so when ordering or consulting, it is important to clarify the commonly used units. Some companies are accustomed to using mm, while others may use c (wire) or strip, as well as um (micrometer). The most common mistake is to make a mistake in ordering 0.025mm and 0.25mm, with 0.025mm=2.5c=25um and 0.25mm=25c=25um. It is estimated that many companies have experienced this situation, claiming a thickness of 25, and then receiving the sample is far from the requirements they stated. The ultimate reason is that the unit is not unified, or the title is not unified, completely out of habit. Therefore, consistency in the use of units is very important, and all enterprises must pay attention to this.
