WeProFab Final Solution

• Processes descriptions:
  • Single-layer Film:​ Plastic pellets are heated and melted, then blown into a thin film. The process involves Extrusion – Inflation – Cooling & Setting – Trimming.
    • Extrusion:​ The molten plastic is extruded through a die to form a tubular parison.
    • Inflation:​ Compressed air is introduced into the parison, inflating it like a balloon to achieve transverse stretching and thinning.
    • Cooling & Setting:​ After cooling, the film is flattened or wound into a tube.
    • Trimming:​ The edges of the film are trimmed.
    • Multi-layer Film:​ Lamination is performed to combine multiple layers.

• Critical to Quality: Nylon and PE double-layer composite, the factory is capable of producing multi-layer composites (e.g., up to 4 layers).
• Final products description: LLDPE + Nylon double-layer composite film.
