Film Slitting Blades

Film slitting blades for converting lines—built to reduce edge dust, stabilize tracking, and keep cut quality consistent across long runs.

Clean-edge film cutting blades

Film Slitting Blades We Manufacture

Film slitting blades for clean, high-speed cuts—edge geometry, grinding precision, and surface finish optimised to reduce dust, prevent edge tearing, and maintain consistent slitting performance over long runs.

Film Slitting Methods

Film and flexible materials are typically slit by razor slitting, shear slitting, or score/crush slitting. Each method drives different requirements for blade stiffness, edge geometry, and mounting stability.

Razor Slitting Blades

For thin, flexible webs where fast changeover and clean separation are priorities.

  • Slotted Razor Blades
    Reliable positioning in slot holders, efficient replacements, and stable performance on high-speed rewinding lines.
  • 3-Hole Razor Blades
    A common format for 3-hole holders. Options available for corner style and edge preparation to match handling and cut behavior.
  • Injector Razor Blades
    Used with injector-style holders where quick, compact loading is required.
  • Single Edge / Double Edge Razor Blades
    Selected by holder design and changeover habits. Edge preparation can be tuned for cleaner edges and better stability on challenging films.

Common Slitting Issues We Target

These are the most frequent reasons film edges become unstable on the line—and where blade spec changes deliver clear gains:

  • Dust / angel hair / rough edges
    Usually linked to edge wear progression, unstable engagement, or film structure abrasiveness.

  • Edge tearing or inconsistent slit line
    Often caused by mismatch between slitting method and blade format, or insufficient mounting stability.

  • Fast dulling / short change intervals
    Common with abrasive coatings, filled films, or adhesive contamination; may require coating + edge preparation changes.

  • Tracking sensitivity at speed
    Thin-blade vibration or holder fit can amplify cut variation; stiffness and fit consistency become key.

How We Keep Film Slitting Edges Repeatable

To keep film slitting results stable across repeat orders, we control the factors that most directly affect edge quality and change intervals:

  • Material traceability to keep performance consistent across batches
  • Heat treatment control for predictable hardness and edge stability
  • Edge preparation + grinding consistency so slit quality doesn’t drift over time
  • Thickness and mounting fit checks (razor hole/slot patterns or circular OD/ID/bore features)
  • Protective packaging to prevent micro-chips and edge damage during shipping and handling

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.

  • Which blade type should I choose for my line?

    Start with your slitting method and holder design. Razor lines typically use slotted / 3-hole / injector formats, while shear and score/crush systems use top & bottom circular slitters and anvils.

  • What coating should we consider for adhesive or high-friction films?

    Low-friction, wear-stable coating directions can reduce drag and heat buildup and help slow down wear—especially when adhesive transfer is part of the issue. We’ll recommend based on your film stack-up and run profile.

  • Can you manufacture by sample or drawing?

    Yes. Send a drawing or a physical sample, plus photos of your holder or mounting area, and we’ll match the mounting details and edge specification.
