Specify pitch, tie width, depth, and pattern—get perforation tooling optimized for your web, speed, and tear requirements.
Perforating and serrated blades are tooth-pattern cutting tools used to create controlled separation in webs, sheets, and packaging materials. Perforation tooling creates a repeatable tear line by alternating cut and tie sections, while serrated blades improve bite and traction to reduce slipping and enable cleaner cutting of challenging materials.
Performance depends on the full system: tooth geometry, backing/anvil conditions, registration, runout, line speed, and material behavior. Davion supplies made-to-print tooling or build-to-sample replacements with controlled patterns for repeat orders.
A consistent tear line typically depends on:
tooth-to-tooth spacing that sets perf frequency.
the uncut portion that controls tear strength.
affects separation reliability and fuzzing/dusting.
ensures tear line aligns with graphics, seals, and product features.
If you don’t have these defined, share your material, thickness, and desired tear behavior (easy tear vs secure hold). We can help translate performance goals into a practical pattern.
What it is: Circular perforating wheels with a repeating cut/tie pattern.
When used: Packaging films, pouches, and wrappers requiring predictable tear initiation.
What it is: Fine-pitch perforation patterns designed for controlled tear without aggressive penetration.
When used: Thin films, label stock, and applications where aesthetics and low dust are important.
What it is: Deeper or stronger tooth geometries for thicker or tougher materials.
When used: Laminates, heavier films, and products needing robust separation.
What it is: Perforation sections separated by non-perf “skip” zones.
When used: When tear lines must appear only in specific product regions or formats.
What it is: Perforation designed to repeat in sync with product graphics or sealing areas.
When used: Printed packaging where tear lines must align with artwork or functional features.
What it is: Perforation optimized to remove a strip cleanly with controlled tie strength.
When used: Overwraps, lidding, or tear-strip features in consumer packaging.
What it is: Patterns designed to initiate openings and consistent tear propagation.
When used: Bag making and pouch applications where opening performance is critical.
What it is: Linear perforation knives used in guillotine or intermittent stations.
When used: Sheet-based operations or intermittent web processes.
What it is: Straight blades with serration to increase bite and reduce slipping.
When used: Tough films, rubbery materials, or products that skid on smooth edges.
What it is: Serrated knives used to trim web edges with improved traction.
When used: Slippery webs where trim stability impacts winding and downstream handling.
What it is: Circular blades with serration patterns for increased bite and reduced slip.
When used: Elastomers, tough films, and materials that skid on smooth edges.
What it is: Tooth-pattern edges beyond standard serrations, including custom tooth forms and pitches.
When used: When traction, tear behavior, or bite must be tuned to a specific material, tension regime, and station mechanics.
What it is: A wave-profile edge that alternates contact points along the cut, reducing continuous contact length.
When used: When you need controlled bite with reduced drag—often helpful where slip or pickup occurs on certain webs.
What it is: Disposable razor-format blades used in dedicated holders for very low cutting force and rapid changeover.
When used: Thin films or quick-change stations where frequent swaps are expected and consistent edge initiation is critical.
What it is: Serration pitch tailored to material stiffness and thickness.
When used: Fine for thin webs, coarse for thicker/tougher products requiring grip.
What it is: Adjusting tooth tip and land geometry to tune penetration and durability.
When used: Pointed for initiation, flatter forms for durability and reduced snagging.
What it is: Patterns designed to reduce fiber pull and fuzzing.
When used: Nonwovens where edge cleanliness affects bonding, sealing, or aesthetics.
What it is: Tooth geometry selected to avoid tearing, edge wave, and ragged perforation.
When used: Foil laminates and barrier structures sensitive to crack propagation.
What it is: Coating/finish choices to reduce pickup and heat generation at tooth edges.
When used: Adhesive films, tacky laminates, foams, and residue-forming materials.
What it is: Stainless-based tooling for wet, humid, or washdown environments.
When used: Food-adjacent packaging and processes where corrosion pits damage tooth edges.
What it is: Tooling replicated from an existing sample with verified pattern and interface.
When used: OEM replacements where CAD/drawings are not available.
Tooth-pattern tools are sensitive to edge chipping, wear, and buildup—material and surface strategy must match the duty cycle.
common for general perforation/serration wear-toughness balance. → Materials: Carbon & Tool Steels
corrosion resistance for humid/wet/washdown environments. → Materials: Stainless Steels
for abrasive webs or extreme wear needs (application dependent). → Materials: Carbide
can reduce pickup and wear; selection depends on web chemistry and temperature. → Coatings & Surface Treatments

Repeatable perforation depends on repeatable geometry. Inspection scope can be aligned to your requirements:
Perforating and serrated tooling is commonly used in:
easy-tear features, tear strips, pouch opening performance
ticket/receipt paper tear lines, tissue perforation, printed web separation
packaging webs and food-adjacent converting lines
tough films, elastomers, and specialty sheet products
controlled opening features in packaging formats (application-defined)
Patterns require specific inputs. Provide what you have—minimum is acceptable.
validate tear behavior, aesthetics, and consistency before scaling.
controlled revision handling to maintain tooth geometry and pattern repeatability.
