Trimming Teeth Blades for Aluminum Foil Circular Shape

This rotary cutting blade (serrated cup cutter) is designed for high-speed industrial packaging and filling lines. Here is how this specific design applies to the 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 trims 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.
