High-Speed Extrusion Film Coating Machine is a fast-operating production device used for film coating on plastic or paper surfaces. This machine enhances durability, waterproofing, protection, aesthetic properties, and strengthening of materials used in packaging by applying plastic film or protective coating to various surfaces.

Our type of machine offers manufacturers the ability to perform high-quality coating at high speeds and is commonly used in industries such as packaging, automotive, electronics, and food.

The series high-speed Extrusion Film Coating Machine adopts advanced technologies including integrated winding drying, surface treatment, edge trimming, and rewinding with a paper-plastic composite unit (non-adhesive composition unit), photoelectric tracking, electric spark treatment (corona discharge), linear speed and material length measurement, digital display screen, fully automatic tension and suction control, etc. The machine is designed with a centrally controlled PLC integrated with electrical and gas systems. The highly efficient corona unit and automatic hydraulic changing filter sieve are first-of-their-kind innovations, which can increase the peeling strength of products.

Working Principle of the High-Speed Extrusion Film Coating Machine

Extrusion Process: Plastic granules are fed into the extrusion machine and melt into a liquid state at high temperatures. The molten plastic is formed into a thin film layer through an extruder. This film is then applied onto the material to be coated.

Coating Process: The extruded plastic film is coated onto the target material (paper, plastic, etc.) at a specific thickness and speed. This coating process creates a strong bond between the film and the surface, making the material durable, waterproof, or aesthetically pleasing.

Cooling and Solidification: After coating, the extruded film is cooled and solidified. This stabilizes the coating and strengthens the bond between the material and the film. After cooling, the film fixation process is completed and the coating becomes durable.

Cutting and Packing: After the coating process, the material is cut and packed as needed. This step transforms it into the final product according to the manufacturer’s requirements.

Features of the High-Speed Extrusion Film Coating and Laminating Machine

High-Speed Operation: These machines can operate at speeds exceeding hundreds of meters per minute, providing large production capacities and efficiency. High speed is crucial for industries aiming at large production volumes.

Film and Coating Thickness Adjustment: The film thickness can be adjusted according to the properties of the material to be coated and the desired quality, meeting various coating requirements.

Various Coating Materials: Typically polyethylene (PE), polypropylene (PP), polyester (PET), and other plastic materials are used, but bio-based plastics, protective coatings, or composite materials can also be applied. Coating can also be done on surfaces like paper, cardboard, and textiles.

Eco-Friendly Features: Some machines support environmentally friendly production by using recyclable materials. They may also feature low energy consumption and minimal waste generation.
