Serrated Cutting Blade with 3–20 mm Tooth Pitch for Food Packaging Machines

Serrated Cutting Blade for Food Packaging Machines

This serrated cutting blade is intended for packaging-material cutting in food packaging equipment. The listed tooth pitch range is 3–20 mm. Final tooth geometry, blade dimensions and mounting details should be matched to the machine and packaging substrate.

The blade specification should account for the film or packaging material, cutting motion and required separation quality. Use in food packaging machinery does not by itself establish suitability for direct food contact.

Address Incomplete Cuts and Material Dragging

Incomplete separation, stretched film and irregular cut edges can occur when the blade is worn or its tooth geometry does not suit the material. Blade alignment, material tension and cutting clearance can also affect the result.

Before replacing a knife, compare the existing tooth profile, bevel direction and mounting position. These details help distinguish a blade-selection problem from a machine-setting problem.

Match Tooth Pitch to the Cutting Application

Tooth pitch describes the spacing between adjacent teeth. It is one part of the cutting-edge specification and should be considered together with tooth height, profile and bevel.

When selecting within the listed 3–20 mm range, provide the packaging material’s thickness and layer structure, along with the cutting motion. For replacement orders, a drawing of the existing edge is more useful than tooth pitch alone.

Technical Specifications

The ranges above do not describe one fixed blade configuration. Final requirements should be recorded in the approved specification.

Application Review

Flexible Packaging Film

Identify the film type, thickness and whether it is a single-layer or laminated structure. Describe how the material is supported and tensioned during cutting.

Coated or Laminated Packaging

Include details of coatings, adhesives and material buildup observed on the existing blade. These factors should be considered when reviewing the edge and surface specification.

Replacement Blades for Packaging Lines

Confirm the exact machine model, holder dimensions and cutting-edge position. A blade with similar overall dimensions may still require a different tooth profile or mounting arrangement.

Information Needed for a Quotation

• Dimensioned blade drawing or existing blade specification.

• Tooth pitch, height, profile and bevel orientation.

• Mounting-hole and slot dimensions.

• Packaging material type, thickness and layer structure.

• Required steel grade and hardness, if specified.

• Machine model, operating conditions and order quantity.

Include photographs of the existing blade and sample cut edges if you are troubleshooting incomplete separation or uneven cutting.

Frequently Asked Questions

Does a higher hardness always give better results?

No. Hardness must be selected with the steel grade, edge geometry and cutting conditions. Wear resistance and resistance to chipping both matter.

Can I choose the blade by tooth pitch alone?

No. Tooth height, bevel, blade dimensions and mounting details must also match the application.

Is this blade intended to cut food directly?

This description concerns packaging-material cutting. Direct food-contact use requires separate confirmation of the material, surface treatment and applicable requirements.

Is the blade compatible with every food packaging machine?

No. Compatibility must be checked against the specific machine’s holder, mounting pattern, cutting motion and clearance.
