Blades for the packaging industry

Product Description

At Castillo we manufacture blades and cutting tools for the packaging industry, with a special focus on corrugated cardboard and flexible packaging. Our solutions are designed to maintain a clean, stable, and repeatable cut on high-production lines, reducing downtime, improving finish quality, and increasing process efficiency.

In addition to cutting, in packaging, sealing is critical to the final quality of the package and the continuity of the line.  That is why we place importance on sealing optimization: incident analysis, material testing, and parameter adjustment (temperature, pressure, and time) to achieve consistent sealing at maximum speed.

Types of tools for the packaging industry

Circular blades

For longitudinal slitting and continuous in-line operations.

End cutting blades

For slitting and cut-to-size on the production line.

Slotting blades

Designed for grooving operations in corrugated cardboard, delivering precision and cutting stability.

Blades for continuous lines (longitudinal cutting on machine)

For integrated in-line equipment that requires reliability and consistency.

Dies and molds (materials and manufacturing to specification)

Die-cutting and cutting solutions for converting processes, made to drawing or sample.

Blades for bag manufacturing (flexible packaging)

Specific blades for production lines of supermarket bags and other bag formats, optimized for a clean, consistent cut in film, improving line continuity and finish quality.

Sealed

In packaging lines, poor sealing causes rejects, downtime, and complaints. That is why we treat sealing as a critical part of process performance:

Analysis of sealing problems (marks, lack of closure, leaks, wrinkles, material variations).
Testing new materials and validation under real conditions to ensure the change works before implementing it.
Optimization of process parameters (temperature, pressure and time) to improve consistency and speed without compromising quality.
Support in machine integration when the system needs to be adjusted to stabilize the result.

Custom manufacturing

We can manufacture from drawings, samples, or references, adjusting dimensions, holes, and geometries for safe assembly and stable performance. This allows us to adapt the solution to your line, your material, and your way of working, reducing downtime and improving the quality of the final product.
