Film Slitting Blade

Film slitting operations demand precision, reliability and long‑term durability. A properly engineered film slitting blade ensures clean edge quality, higher yield and reduced downtime for your film converting line. In this page, you will explore our industrial film slitter knife solutions, see how to choose the right one and understand why we deliver value for B2B clients.

Partner with us for reliable industrial blade solutions

Whether the machinery you work with has specific machine blade specifications from the original equipment manufacturers (OEM), or you need to create an industrial knife blade that is unique to your converting application, we has the custom industrial blade solutions you need.

Why Film Slitting Blade Matters

When you slit large rolls of film into narrower widths, the blade is a critical component. If the blade edge is dull, misaligned or the wrong material, you risk edge corrugation, "angel hair" strands, excessive scrap and unplanned stops. According to industry experts, high‑quality blades minimise wear and improve roll edge quality. For manufacturers and converters of plastic film, the right blade directly supports production performance, yields and cost control.

Typical Applications


  • Applications
    Plastic film extrusion and converting (PE, PP, PET)
  • Applications
    Flexible packaging film rewinding
  • Applications
    Label stocks, tape materials and adhesive film slitting
  • Applications
    Lamination lines requiring high edge quality and minimal downtime

Materials & Construction Options

We offer a variety of blade constructions tailored to your application’s demands:

  • Stainless steel blades with ultra‑hard coatings — ideal for moderate duty film converting.
  • Ceramic‑coated or full ceramic blades — built for abrasive films, higher wear resistance and longer service life. 
  • Customised shapes (3‑hole, slotted, single edge) to fit your slitter rewinders and mounting systems.

Selecting the right material and construction enhances cut precision, extends blade life and reduces machine downtime.

How to Choose the Right Film Slitter Knife

  • Film material and additives

    Thick, filled or abrasive films wear blades faster.

  • Blade holder and mounting type

    Ensure compatibility with your slitter so the blade seats correctly.

  • Cut quality requirements

    Do you require burr‑free edges, minimal dust and consistent width?

  • Production speed and blade change frequency

    Higher speeds may demand advanced coatings or harder materials.

  • Cost of downtime vs blade cost

    Sometimes a premium blade saves more in reduced stops and scrap.

Frequently Asked Questions

Do you have any questions about our products and how to use them? We have compiled the most frequently asked questions and answered them. If your question is not listed here, please contact us.

  • How often should the blade be changed?

    It depends on film material, additives, speed and machine condition. As a rule of thumb, monitor edge quality and increase frequency if you observe burrs or increased scrap.

  • Can you manufacture custom shapes?

    Yes. We can produce 3‑hole, slotted, single‑edge or other formats to suit your mounting system and film width.

  • Do you support global shipping?

    Yes. We ship globally and provide logistics support for industrial clients.
