How to distinguish
from
From the appearance,
and the same specifications of plastic coated with silicon
There is no difference; and it is difficult to distinguish between the silicon-coated film
and the ordinary film with the naked eye, but you only need to use a few simple tools and operations to distinguish it well. To find out the difference between them, a paragraph
, a pen, and a small hand-teared paper test.
First of all, let’s take a look at the difference between ordinary
and
. Cut out a section of
and stick it to these films respectively. Then peel it off. The ones that feel easy to peel off and make no noise during the peeling process are the silicone-coated release films. The ones that are more difficult to peel off and make a squeaking sound during the peeling off process are those. Ordinary without silicone coating
. This method can also be used to distinguish whether a single silicone release film is coated with silicon on one side or a double silicone release film is coated with silicon on both sides. It can even compare which side is coated with silicone and the peeling rate. Another method is to use a water pen to test and scratch the surface of the film. There will be no ink on the surface of the release film, while there will be ink marks of varying shades on the ordinary film.
You can't tell the difference between plastic ones
and the same specifications
in appearance, but you can also tell the difference using the above method.
The appearance of glossy ordinary paper and laminated paper are sometimes very similar, but if you tear them apart by hand, ordinary paper only has fiber hair at the torn edge, while laminated paper has only fiber hair at the torn edge. Wood fibers also have some small diaphragms. If you use
to test, the coated paper will make a sound when removing the tape, but nothing will stick to the tape, while the shiny ordinary paper will stick to the surface of the paper

and
Sometimes, it is difficult to distinguish between silicone-coated glassine release paper and ordinary laminate-coated silicone release paper with the same specification and color when placed on the desktop, and They also have the same release characteristics. However, glassine paper is made of high-pressure light, so the paper is more uniform and smooth, and is generally more transparent, so you can easily distinguish these two similar papers by looking at the transparency and uniformity of the paper as long as they are facing a bright light. , If it doesn’t work, just tear it open with your hands. The film fragments you can see are the coated paper.
