Solution for gluing on release film [film coating machine]

Release film is a very common film, used in plastic film, electronic products and other industries, and its film-making research is also widely used. This article mainly introduces the solution for preparing the adhesive film on the release film, using an experimental automatic film coating machine with vacuum adsorption.

To prepare an adhesive film of tens of microns on the release film, there are generally two difficulties in manual scraping, one is the precision control of the film thickness, and the other is how to flatten and fix the film. The former can be solved by choosing a better Film Applicator, but whether wire bar or drawdown blade coating is used, the unevenness of the substrate directly affects the difficulty of film production. The latter requires a Vacuum Pump to drive a vacuum plate to absorb bopp, PET and other films on the coating film substrate. It is an effective way to choose a suitable coating method according to the viscosity and characteristics of the fluid.

The following is the video of the experiment case of NBCHAO applying glue on the release film. This laboratory has a multi-layer coating film. Here is a small clip of it, the effect of the second coating film.

Attach a few effect pictures, pay attention to the flexible substrate coating film, it must be equipped with vacuum adsorption to keep the substrate smoother.
