Distinguishing between laminated paper, release paper and release film

Visually, there is no difference between laminated paper and silicone-coated plastic release paper of the same size; and it is not easy to distinguish silicone-coated release film from ordinary film with the naked eye, but you only need to use a few simple tools and operations to tell the difference between them, a piece of tape, a signature pen, plus a small hand-tear paper test.

Let's look at the difference between ordinary plastic film and release film. Cut a piece of tape and stick it to these films respectively, and then uncover them. The ones that feel easy to uncover and have no noise during the uncovering process are silicone-coated release films, while the ones that are harder to uncover and have a squeaky sound during the uncovering process are ordinary plastic films that are not silicone-coated. www.susumino.com南京 Sumino Seiko film laminator

In this way, it is possible to distinguish between single-silicon release films with silicon coating on one side and double-silicon release films with silicon coating on both sides, and even to compare the amount of silicon coating on one side and the size of the peel rate. There is also a method to test the film surface with a water pen, and there is no ink on the surface of the release film, while there are ink marks of varying shades on the ordinary film.

You can't tell the difference between plastic release paper and laminated paper of the same size in appearance, but you can tell the difference between them by using the above method. www.susumino.com南京住野精工淋膜机

Glossy plain paper and laminated paper can sometimes look similar, but if you tear them apart by hand, the plain paper will have only fiber hairs at the torn edge, while laminated paper will have small pieces of film in addition to wood fibers. If tested with tape, the laminated paper will rattle as the tape is removed, but nothing will stick to the tape, while the glossy plain paper will stick to the coating and wood fibers on the surface of the paper.

Sometimes, it is difficult to distinguish between a silicone coated Grassian release paper and a plain laminated silicone coated paper with the same specifications and color on the desktop, and they have the same release characteristics. But Grassian paper is made of high-pressure light, so the paper is more uniform and flat, and generally more transparent, so you just need to look at the transparency and paper uniformity of these two similar papers against the light is easy to distinguish, really can not, tear open by hand, you can see the film fragments is laminated paper.


Film laminating machine is a machine equivalent to plastic sealing, used in the production line is very efficient, and environmentally friendly non-polluting coating thickness uniform bonding is also very high. It is only in recent years that the domestic application has gradually started and it is the future development trend to replace dry lamination and hot melt adhesive coating. www.susumino.com南京住野精工淋膜机

Next, a brief introduction to the use of film laminating machine several industries.

First, the food industry, for example, the appearance of food is a lot of plastic sealing, especially with oily food, so the food wrapping paper is the masterpiece of the laminating machine;

Second, the packaging industry, the development of laminating machine in the packaging industry is gradually improving, especially with the rapid development of China's dairy industry, the competition between the dairy manufacturers intensified, which led to the development of its related processing and laminating machine packaging industry;

Thirdly, the photo paper industry, because the laminating machine is relatively small and efficient, it is very suitable for the use of photo paper.
