Luguan Plastic Bandera 7-Layer Co-Extrusion Technology for High-Performance Agricultural Films

1. Why Advanced Equipment Matters in Agricultural Film Production
In modern agriculture, plastic films are no longer simple crop covers. For greenhouse growers, distributors, and agricultural project companies, film performance directly affects light transmission, heat retention, UV resistance, anti-fog performance, mechanical strength, and service life.
That is why advanced extrusion technology has become one of the key factors when choosing an agricultural film supplier.
2. What Is Bandera 7-Layer Co-Extrusion Technology?
Bandera 7-layer co-extrusion technology refers to a multi-layer blown film extrusion process that combines different functional layers into one integrated agricultural film structure.
Compared with conventional single-layer film, 7-layer co-extruded film provides more structural design space. Each layer can be designed for a specific function, such as UV resistance, thermal retention, anti-fog performance, light diffusion, mechanical strength, or crop-specific optical performance.
For agricultural film buyers, this means better customization capability and more stable product performance across different climates, crops, and greenhouse structures.
3.How Bandera Equipment Supports Film Stability？
——More Consistent Layer Distribution
Multi-layer co-extrusion requires precise control of each film layer. Stable layer distribution helps ensure that functional materials and additives are distributed more effectively, supporting consistent product performance from batch to batch.
——Better Combination of Multiple Functions
A high-performance greenhouse film may need UV resistance, anti-fog performance, high transparency, thermal retention, and mechanical strength at the same time. 7-layer co-extrusion provides more possibilities for combining these functions in one film.
——Wider Customization for Global Markets
Different markets have different climate conditions and crop requirements. Films used in hot regions may require cooling and light diffusion, while films used in cold regions may require stronger thermal retention.
With multi-layer co-extrusion technology, Luguan can customize film structures according to crop type, climate, greenhouse design, service life, and customer branding requirements.
4.Why 7-Layer Co-Extruded Films Are Suitable for High-Value Agriculture？
As greenhouse agriculture becomes more professional, growers and distributors are looking for films that support stable crop growth, not just basic covering.
A well-designed 7-layer greenhouse film can help improve the balance between transparency, diffusion, thermal insulation, anti-aging performance, and mechanical strength.
This makes 7-layer co-extruded films especially suitable for applications such as:

5.Why Equipment Choice Matters to Buyers？
For international buyers, the equipment behind the film is not just a factory detail. It directly affects product stability, delivery reliability, and long-term customer satisfaction.
A stable co-extrusion platform can help reduce common purchasing risks, such as:

6. How Luguan Applies Bandera Technology？
Qingzhou Luguan Plastic Co., Ltd. applies Italian Bandera equipment and 5-layer / 7-layer co-extrusion technology in agricultural film production. The company manufactures greenhouse films, mulch films, silage films, oxygen barrier films, flame retardant films, shrink films, and other functional film products.
Luguan supports customized film thickness, width, color, function, lifespan, packaging, and OEM/ODM branding. Its available product range includes greenhouse films such as cooling film, thermal film, light conversion film, bubble film, light diffusion film, UV-stabilized film, algae-proof film, and white-black-white film.
This allows global buyers to match film structure with local crop type, climate condition, greenhouse design, and market positioning.
