Custom Metallized Polypropylene Film

Production Processes

• 

  Coating

  Coating

  This is the initial step where a thin layer of metal, usually aluminum or zinc, is deposited onto a plastic film, like polypropylene or polyester. This metallization process is crucial for creating the dielectric layer in capacitors.

• 

  Coating Inspection

  Coating Inspection

  After the coating process, the metallized film undergoes inspection. This step is essential to ensure the consistency and quality of the metallization, checking for defects like uneven coating, breaks, or impurities.
• 

  Slitting

  The large rolls of coated film are then slit into narrower widths. This process is tailored to meet specific requirements for different types of capacitors, depending on their intended use and specifications.

  Slitting Inspection

  The slit materials are inspected to ensure that the cutting process has been accurate and that the film meets the required dimensions and specifications. This may involve checking the width, edge quality, and any potential damage incurred during slitting.

  Small Packaging

  Small Packaging

  After inspection, the slit film is packaged into smaller units. This packaging is typically done to make handling, transportation, and storage easier and more efficient, especially if the film is sent to another location for further processing.

  Bulk Packaging

  Finally, these smaller units are packaged in bulk. Bulk packaging is often used for final shipment to customers or distributors and is designed to protect the materials during transit and to facilitate easier bulk handling.
