Production process flow of PET PI gold-plated film, tin plated film, PE protective film

The production process of PE protective film plays a crucial role in the quality of the product to a certain extent. Because if there is a problem in any link of the production process of PE protective film, it is likely to cause some minor defects in the PE protective film.

Production process of PE protective film:

Film blowing - printing - coating - testing - rewinding - slitting - packaging

Blown Film
Blow molded film is a thin film made by melting and plasticizing plastic in an extruder, extruding it into a film tube through a circular die, and then blowing and cooling it with compressed air to shape it.

print

The gravure printing machine immerses the printing plate in an ink tank, removes ink from non engraved areas using a scraper, and then transfers the ink to the substrate under the action of an embossing roller.

coating

It is necessary to make adhesive according to the specifications and applicable products of the PE protective film, and then hand it over to a professional coating machine to evenly apply the adhesive to the substrate.

detection

During the production process of ingredients, blown film, printing, and coating of PE protective film, professional quality inspectors will conduct product quality inspection.

rewinding

Semi finished products and finished products are rewound on the inspection machine. If there are errors in shape, size, and color between the sensor feedback pattern and the standard sample input into the computer beyond a certain range, the inspection machine will automatically stop and detect them. The inspection process can reduce waste in subsequent processes and improve product quality.

cutting

The slitting process is the process of dividing large film rolls into the required size specifications. Nowadays, with the increasing application of automatic packaging equipment, there are more and more forms of film rolls leaving the factory.

package

Transport the finished PE protective film that has been tested and cut to the packaging machine for professional packaging.

The content introduced above is the production process of PE protective film. However, due to the production process, the PE protective film may vary depending on the equipment used, the type of adhesive, and the type of substrate.
