An automatic Film Applicator is a kind of equipment that is widely used in industrial production, and its role is to evenly apply the coating to the surface of different types of materials. Among them, BOPP (biaxially oriented polypropylene) film is a common material that is widely used in packaging, labeling, advertising and other fields. BOPP films usually need to be glued to their surface in order to bond or print in a subsequent process. This article will explore the application of automatic film coating machine to apply glue on BOPP film, and gain an in-depth understanding of its working principle, advantages, and application scenarios in different industries.
The working principle of the automatic film coating machine mainly includes the coating system, the drying system and the control system. A coating system usually consists of a coating roller, a tun and a glue supply system. The glue is conveyed to the glue bath via the glue supply system and then applied on the coating rollers. Whereas, the coating roller rotates to evenly apply the glue to the surface of the material to be treated. After the coating is complete, the material passes through a drying system, usually by drying or UV curing, to ensure that the glue dries quickly and bonds to the surface of the material. The control system is used to monitor and adjust the parameters during the coating process to ensure the thickness and uniformity of the coating.
Application of automatic film coating machine on BOPP film
Packaging industry: In the packaging industry, BOPP film is often used to make various types of packaging materials, such as bagged food, cosmetics packaging, etc. The automatic film coating machine can apply glue to the surface of BOPP film to enhance its adhesion and water resistance, thereby improving the quality and durability of the packaging.
Label manufacturing: In the label manufacturing industry, BOPP film is often used to make various types of labels, such as commodity labels, barcode labels, etc. Through the automatic film coating machine, glue can be applied on the surface of BOPP film, and information such as words and patterns can be printed on it to realize the function of label pasting and identification.
Advertising industry: In the advertising industry, BOPP film is usually used to make outdoor advertising, promotional posters, etc. The automatic film coating machine can coat the surface of BOPP film with glue and print a variety of colorful advertising content on it to achieve visual effect display and publicity.
Electronic product manufacturing: In the electronic product manufacturing industry, BOPP film is often used to make protective films and screen protectors for electronic products. The automatic film coating machine can apply glue on the surface of BOPP film, and add scratch-resistant, waterproof and other functional coatings to it to enhance the durability and use experience of electronic products.
Procedure
The operation process of the automatic Film Applicator on the application of glue to BOPP film usually includes the following steps:
Before starting the operation, the automatic Film Applicator needs to be inspected and prepared. Make sure that the coating system and drying system are in working order, that there is an adequate glue supply in the glue tank, and that the pressure and speed of the coating roller are adjusted.
According to the requirements of the coating glue and the characteristics of the BOPP film, the parameters of the automatic film coating machine are set. This includes parameters such as the coating thickness of the glue, the coating speed, the drying temperature, etc.
The BOPP film to be processed is loaded into the feed end of the automatic Film Applicator. Ensure that the position and tension of the film are adjusted appropriately to ensure stability and uniformity during the coating process.
Start the automatic Film Applicator and start applying the glue to the surface of the BOPP film. The coating roller will apply the glue from the glue tank to the surface of the film, ensuring an even and consistent coating layer.
After the coating is completed, the BOPP film is cured through a drying system. Depending on the characteristics of the glue, drying or UV curing can be selected to ensure that the glue dries quickly and adheres to the surface of the film.
After coating and drying, the coated BOPP film is inspected for quality. Check the thickness, uniformity and adhesion of the coating layer to ensure that the product meets the quality standards required by the customer.
The coated BOPP film of acceptable quality is collected from the automatic film coating machine, and post-processing such as packaging and labeling is carried out for subsequent production and delivery.
After the operation is completed, the automatic Film Applicator is cleaned and maintained. Remove the residual glue on the glue tank and coating roller, check whether the parts of the equipment are operating normally, ensure the normal use of the equipment and prolong the service life of the equipment.
conclusion
The application of automatic film coating machine to apply glue on BOPP film has a wide range of application prospects and market demand. By understanding its working principle, advantages, and application scenarios in different industries, you can better understand the importance and role of automatic Film Applicators in industrial production. With the continuous progress of technology and the continuous growth of market demand, it is believed that automatic film coating machines will play an increasingly important role in the future development, providing more efficient and accurate coating solutions for the production of all walks of life.
