Effective Solutions for Severe Adhesion Issues When Cutting Film Materials

In the packaging and slitting industry, film materials often stick to blades during cutting due to their softness and strong surface adhesiveness. This phenomenon not only degrades cutting quality but also causes frequent machine downtime, affecting overall production efficiency. Based on current industrial practices, here are several effective solutions to help companies achieve efficient and stable film cutting.

Main Causes of Film Blade Adhesion

High surface adhesiveness of materials

Films like BOPP, CPP, and PET naturally have sticky surfaces that easily bond with blades.

Blades without anti-stick coating

Standard blades have higher friction, increasing the risk of material sticking.

Worn or dull blades

Dull edges cause more friction and worsen adhesion during cutting.

Improper cutting parameters

Excessive pressure or too high speed can cause material to be pressed against the blade, increasing sticking.

Environmental humidity

Moisture in the air increases surface stickiness by causing films to absorb water.

Effective Solutions

1. Use Anti-Stick Coated Blades

Select tungsten carbide blades coated with anti-stick layers to reduce friction and prevent material adhesion.

2. Optimize Cutting Parameters

Adjust blade pressure, cutting speed, and angle to avoid over-compressing the material and ensure smooth cutting.

3. Regular Blade Inspection and Replacement

Keep blades sharp and replace worn ones promptly to minimize friction caused by dull edges.

4. Employ Auxiliary Airflow Systems

Use air knives or airflow near the cutting zone to disperse material and reduce contact adhesion.

5. Control Workshop Humidity

Maintain appropriate humidity levels using dehumidifiers or ventilation to prevent films from becoming overly adhesive.

Conclusion

Adhesion during film cutting is a common challenge in modern packaging production. However, with the right choice of anti-stick blades, optimized cutting settings, and controlled production environment, companies can significantly reduce this issue, improving both cut quality and production efficiency.
