Multi-Layer EVOH Cast Film Co-Extrusion Line

Introduction of Multilayer Co-Extrusion Specialty Cast Films

1. EVOH High Barrier Film

• Product Features:

• EVOH (Ethylene Vinyl Alcohol Copolymer) is a high-performance barrier material, effectively blocking moisture and oxygen.

• Common structures include 5-layer, 7-layer, or 9-layer co-extrusion forms, such as PP(PE)/ADH(EVA)/EVOH(PA)/ADH(EVA)/PP(PE).

• Uses a distributor or in-mold composite die to precisely control the usage of EVOH, reducing costs while ensuring barrier performance.

• Applications:

• Food packaging (e.g., frozen food bags, vacuum packaging).

• Electronic product packaging (moisture-proof and oxidation protection).

• Technical Parameters:

• Model: GWS 90/75/65

• Layers: 5 layers, 7 layers, 9 layers

• Width: 800-2100mm

• Thickness: 0.012-2mm

• Line Speed: 200-250m/min

2. Biomedical Packaging Film (Asymmetric Structure)

• Product Features:

• Asymmetric cross-sectional design allows for precise adjustment of the thickness and performance of each layer according to specific requirements.

• Suitable for biomedical packaging scenarios that demand high barrier properties, high strength, and precise dimension control.

• Special production processes ensure the film is flat, without deformation or shrinkage.

• Applications:

• Medical packaging (e.g., infusion bags, pharmaceutical blister films).

• Technical Parameters:

• Model: GWS 90/75/120/65/45/90/75

• Layers: 11 layers, 13 layers, 15 layers

• Width: 800-2100mm

• Thickness: 0.012-2mm

• Line Speed: 70-200m/min

3. Acrylic Rainbow Film

• Product Features:

• Composed of multiple layers of plastic film, with up to 150-270 layers, creating a colorful effect through optical interference.

• Offers high transparency and excellent optical properties, widely used in decorative and optical fields.

• Applications:

• Gift packaging, optical decorative materials, specialty display materials.

• Technical Parameters:

• Model: GWS 90/75/120

• Layers: 150-270 layers

• Width: 1500-2100mm

• Thickness: 0.012-0.1mm

• Line Speed: 70-200m/min

4. PET Decorative Film

• Product Features:

• PET decorative film adopts a two-layer or three-layer co-extrusion structure, with surfaces offering high gloss or soft "skin-feel" effects.

• Suitable for composite use with wood, metal, and plastic substrates in high-end decorative applications.

• Applications:

• Furniture surface decoration, electronic product casings, interior materials.

• Technical Parameters:

• Model: GWS P95/52

• Layers: 2 layers, 3 layers

• Width: 800-1500mm

• Thickness: 0.15-0.5mm

• Line Speed: 30-70m/min

5. PP Decorative Film

• Product Features:

• Manufactured using three-layer co-extrusion technology, PP decorative film is suitable for printing various patterns and offers excellent abrasion resistance and flexibility.

• Provides a wide range of width and thickness options to meet diverse decorative needs.

• Applications:

• Furniture decoration, construction materials, home appliance casings.

• Technical Parameters:

• Model: GWS 75/90/75

• Layers: 2 layers, 3 layers

• Width: 800-1500mm

• Thickness: 0.08-2mm

• Line Speed: 30-70m/min
