Laboratory small coater coated with polyester film on ultra-thin PET film [video demonstration]

Polyester film coated with PET film has a wide range of applications in modern industry, and its main purpose is to enhance the multiple properties of the substrate to meet various demanding application scenarios. First of all, in the electronic and electrical fields, PET film coated with polyester film is widely used in the manufacture of insulating materials and capacitors because it has excellent electrical insulation and heat resistance, and can remain stable in high-temperature environments. Secondly, in the packaging industry, this composite film is used in the packaging of food, pharmaceuticals and other high-value products due to its excellent mechanical strength and barrier properties. The coating not only effectively prevents the penetration of oxygen and water vapor and extends the shelf life of the product, but also prevents the accumulation of static electricity and protects the internal product from static damage. In addition, coated polyester films provide better optical properties, making them widely used in high-end printing and display protection films. By coating PET film with a polyester layer, it can also significantly improve its chemical resistance, making it suitable for environments that need to resist a wide range of chemicals. This coating technology not only improves the overall performance of PET film, but also expands its range of applications in various industries and daily life, meeting the needs of different industries for high-performance materials.

One of the typical applications of small laboratory coaters is the coating of PET films, the improvement of the properties of PET films or the testing of product properties. This case is the application case of the small coating machine of Huinuo laboratory to coat polyester film on ultra-thin PET film, Huinuo film coating machine adopts imported high-precision wire rod + high flatness table, the main high-precision coating film, up to 1 micron, and the accuracy verification is carried out with a Thickness Gauge at the end of the experiment.

The following is the picture of the coating process of this experiment, and the thickness of the coating film tested at the end is 13.1~13.2 microns, the accuracy is less than 1 micron, and it is very uniform.
