Different hardness: several lines of plastic film are commonly known as microns, and one micron is one thousandth of a centimeter. In the photo, the thicker the plastic film, the better. Generally, it is 7-15 silk. If it is more than 15 silk, it will feel hard. If 12 inch uses 10 filament, then 12 inch uses less than 10 filament.

Thickness of plastic packaging film

Thickness of general plastic film: 80mic, 100mic, 125mic, 150mic, 175mic, 200mic.

Unit conversion: 80mic= plastic film thickness 0.08mm, 100mic= plastic film thickness 0. 10mm, 125mic= plastic film thickness 0. 125mm, 150mic= plastic film thickness 0.655.
