Trimming Teeth Blades – Aluminum Foil Circular Shape
Trimming teeth blades for aluminum foil in a circular shape are rotary cutting blades (serrated cup cutters) designed for high-speed industrial packaging and filling lines. Here is how this specific design applies to automated production lines for cream jars, yogurt cups, and cosmetic bottles:
1. Yogurt and Food Packaging Applications
Top-Seal Film Trimming
In yogurt filling lines, containers are filled, and a continuous roll of aluminum foil or plastic film laminate is heat-sealed across the top. This circular serrated cutter drops down to die-cut the individual round lidding away from the main roll.
Tamper-Evident Pull Tabs
The fine, repeating teeth create a clean serrated edge. This edge allows consumers to peel back the lidding easily without tearing or leaving jagged plastic shards.

2. Cosmetics and Creams Applications
Inner Protective Foil Sealing
High-end skincare creams and cosmetic jars typically feature a secondary protective foil layer under the plastic screw cap to preserve formula freshness and prevent leakage during transit.
Custom Neck Sealing
The 124.5 mm outer diameter and specialized inner mounting flange (R40.0 internal radius) make it a heavy-duty cutting tool suited for large neck jars or multi-cavity sealing heads. It securely punches or crops multi-layered barrier liners right after the filling stage.

3. Key Mechanical Features for Production
Clean Cuts
The dense serration profile ensures a clean, fast shear on polymers, foils, and pressure-sensitive adhesives, preventing film dragging or line jamming.
Line Integration
The inner circular shelf featuring 4 threaded mounting holes allows the blade to bolt directly onto automated rotary indexing stations, pneumatically driven punching heads, or capping machine assemblies.
