How to Choose the Right Blade Material for Plastic Film Cutting?

2025-07-18
Latest company news about How to Choose the Right Blade Material for Plastic Film Cutting?

Choosing the right blade material is key to achieving efficient cuts, maximizing tool life, and reducing downtime. Here are the most common materials and how to select them:

1. D2 Tool Steel (High Carbon, High Chromium)

  • Benefits: High hardness (HRC 58–60), excellent wear resistance, cost-effective

  • Best For: Standard PE and PP film applications in medium to high-volume production

  • Consideration: Requires rust prevention in humid environments

2. M2 High-Speed Steel

  • Benefits: Superior heat resistance, higher hardness (HRC 61–63), better edge retention

  • Best For: High-speed bag-making machines and tacky films

  • Consideration: Higher cost but better wear resistance

3. Tungsten Carbide

  • Benefits: Ultra-high hardness (HRC 70+), top-level wear and impact resistance

  • Best For: Cutting abrasive films like recycled or composite materials

  • Consideration: Ideal for automated systems with extreme durability demands

4. Coated Blades (TiN, CrN, etc.)

  • Benefits: Reduced friction, lower heat buildup, anti-stick properties

  • Best For: Continuous, high-speed cutting where film sticking is a risk

  • Consideration: Choose coating based on film material compatibility
