Extrusion casting laminating machine, some manufacturers and users in the industry are used to calling it a film coating machine, also known as extrusion laminating machine, casting machine, extrusion casting machine, casting laminating machine, film coating machine, coating machine, coating laminating machine (inaccurate, actually refers to hot melt rubber scraper coater), is a kind of extrusion molding machinery. It has the advantages of high automation, easy operation, high production speed, uniform coating thickness, high bonding fastness, flat winding, environmental protection and no pollution, saving labor and raw material costs, etc. It has developed and matured in Europe and the United States, and has gradually begun to be applied in China in recent years, which is an inevitable trend to replace dry composite and hot melt adhesive coating composite.
First, the introduction of the film machine
In fact, through the photo, the surface of the canvas with oily liquid on the film layer of about one meter wide small equipment is the real "shower" film machine, generally used in the studio and other industries, belongs to the daily life with small machinery. The composite material production line with high line speed and large width belongs to light industrial machinery, which should be called extrusion casting composite unit according to packaging printing and machinery manufacturing industry standards. The search results of domestic search engines such as Google Chinese and Baidu on the film machine and most of the information about the film machine on B2B, B2C or portal websites are both coexisting, and the photo film machine accounts for the majority, which is easy to confuse people.
Four, the type of film
(1), according to the extrusion speed classification
1. Low speed extrusion casting compound machine
2. Medium speed extrusion casting compounding machine
3. High speed extrusion casting compound machine
(2), classified by the number of substrate layers
1. Single substrate coating machine
2. Multi-substrate coating composite machine
3. 3-in-1 substrate coating machine
(3), according to the type of substrate classification
1. Paper coating machine
2. Plastic film coating machine
3. Non-woven fabric/non-woven fabric coating machine
4. Woven cloth coating machine
5. Mesh coating machine
6. Other substrate coating machine
Five, the application range of the film machine
1. Food industry
2. Packaging industry
3. Beverage industry
4. Pharmaceutical industry
5, printing office industry
6. Engineering and construction industry
7, other composite flexible packaging materials manufacturing
Six, the main role of the film machine
Small film coating machine is a special equipment for photo and packaging
The large is to do paper-plastic composite film, film composite unit, is the high pressure polyethylene (LDPE), OPP film, paper cup paper, paper box paper, trademark paper, melon seed bag paper, cleaning bag paper and aluminum foil, film, cloth and other substrates for a single film, double layer film coating equipment.
Through the photo, the surface of the canvas with oily liquid on the film layer of about one meter wide small equipment is the real "spray" film machine, generally used in the studio and other industries, belongs to the daily life with small machinery. The composite material production line with high line speed and large width belongs to light industrial machinery, which should be called extrusion casting complex unit according to packaging printing and machinery manufacturing industry standards. At present, the search results of Google Chinese and Baidu and other domestic search engines on the film machine and most of the information about the film machine on B2B, B2C or portal websites are both coexisting, and the photo film machine accounts for the majority, which is easy to confuse people.
Suitable for laser printing, inkjet printing photo film, coated paper, back adhesive paper film
● Oil-based coating features: waterproof, moisture-proof, anti-aging, anti-ultraviolet, high yield, and non-destructive picture, can be repeatedly coated. The film liquid is directly attached to the surface of the picture, solidified after ultraviolet irradiation, and should not be shed.
● The main advantages compared with the water-based coating: the finished product after the oil-based coating is more waterproof, sunscreen, non-deformation, and more wear-resistant.
PS: The permeability is increased by more than 15%, the coating liquid can be recycled, the coating is convenient and no waste, fast and low cost.
