Application of 7 Layer Coextrusion Casting Film extruder

1. Seven different kinds and different grades of plastics are extruded through the compound die and the dispenser die to obtain seven or nine layers of films and sheets with different layer ratios with specific properties;

2. It is mainly used in the production experiment of high barrier film. High barrier co-extrusion flow film is plastic packaging material. Its barrier, fragrance retention, moisture resistance, oil resistance, cooking heat sealing performance can be further improved, can be widely used in food, medical, aviation, aerospace, military and so on.

3. In the plastic mixed with various additives, such as stabilizer, flame retardant, colorant, etc., in order to obtain uniform dispersion and has a specific function of the new functional film
   

1. 7-layer co-extruded casting film extruder produces high-quality film materials with high strength, abrasion-resistant, waterproof and moisture-proof properties, which are suitable for all kinds of packaging, construction and agricultural uses.

2. Adopting advanced 7-layer co-extrusion technology, the film materials produced have excellent airtightness, transparency and tensile strength, which can be widely used in food, medical and electronic product packaging industry.

3. 7-layer co-extruded casting film extruder can be applied to the production of film materials of various sizes and thicknesses, so as to meet the needs and requirements of different customers.

4. Based on modular and customizable design, the 7-layer coextruded cast film extruder offers different production configurations and capacities, allowing users to choose freely according to their needs.

5. Efficient production process, intelligent control system and easy-to-operate production process provide users with high-quality, high-efficiency and economical equipment for film material production.

1.7 Layer Co-extrusion Cast Film Extruder produces high quality film. The use of a multi-layer extruder produces a film that is homogeneous, high-strength, tear-resistant, puncture-resistant and moisture-proof. As a result, these films are ideally suited for packaging products that need to be protected.

2.7 Another advantage of the multilayer coextrusion cast film extruder is its versatility. Since different materials can be used in each layer, this flexibility allows the film to offer a variety of properties such as gas and odor barrier, UV protection and easy-open features.

3. It can be adjusted arbitrarily according to the different needs of customers to produce products with different properties and specifications.

1. Medical industry: Co-extrusion casting extruder can produce high-precision medical devices and medical packaging materials, such as syringes, infusion tubes, artificial joints and so on.

2. Automotive industry: co-extrusion casting extruder can produce high strength, high toughness, flame retardant, UV resistance and other properties of automotive parts and exterior parts, such as roof, door, lamps and so on.

3. Electronics industry: co-extrusion casting extruder can produce high-precision, high transparency, high damping and other properties of optical parts and high-performance plastic shell, such as cell phone screens, camera lenses, TV shells, etc..

4. Construction industry: Co-extrusion flow extension extruder can produce building materials and decorative materials with high strength, waterproof, anti-corrosion, sound insulation and other properties, such as partition walls, window frames, wall panels and so on.
