Security VOID Tape Roll Slitting Blades
Roll slitting converts security VOID labelstock from a master roll into narrower rolls before printing, die cutting or label application. Mark the unwind face, liner side and any security-pattern datum; inspect facestock, indication layer, adhesive and liner as separate interfaces.

Where This Cutting Application Appears
Supplied material and process stage
These pages cover converting the supplied security VOID labelstock before application to the protected article. Confirm the actual facestock, indication or release layer, coloured or metallic layer, pressure-sensitive adhesive, liner, print and winding construction. Avery Dennison and 3M examples show polyester constructions that reveal a VOID or other pattern when removal is attempted; they do not define every security tape, prove tamper performance after conversion or specify a MEIRENTE tool.
Installed process checkpoint
Record the complete labelstock stack, parent-roll map, guide datum, blade stations, web support, tension, rewind, trim extraction and the stage at which print or security features are present.
Output and inspection stage
Measure each daughter-roll width and feature clearance; inspect edge lift, adhesive stringing, liner damage, pattern exposure, particles, telescoping and blocking after rewind.
Roll Slitting process boundary
Confirm the complete material stack, installed operation and approved drawing before reviewing a replacement tool.
Roll Slitting setup checkpoint
Record material condition, protected faces, installed interface and downstream handling before a controlled trial.
Roll Slitting acceptance checkpoint
Use customer-approved dimensions and observable defect limits on labelled samples from the same grade, lot and settings.
Define the Required Cut Result
- Measure every daughter-roll width at approved roll positions
- Inspect facestock, adhesive and liner edges separately
- Verify clearance to any print or security-pattern datum
- Compare at-cut edges with rewound roll build, blocking and premature VOID indication
Problems to Diagnose Before Changing the Knife
Width changes while both edges remain fully separated
Compare guide datum, tension, relaxed width, spacer or station position and core alignment.
The facestock edge is clean but adhesive transfers or strings
Map coated face, temperature, dwell, edge contact and the exact parent-roll position.
VOID pattern or coloured layer becomes visible before application
Stop and separate cutting damage from tension, liner release or unintended layer separation.

Acceptance Criteria for a Controlled Trial
Agree how the trial will be judged before changing the knife or machine setting.
- Measure every daughter-roll width at approved roll positions
- Inspect facestock, adhesive and liner edges separately
- Verify clearance to any print or security-pattern datum
- Compare at-cut edges with rewound roll build, blocking and premature VOID indication
Knife Forms That May Be Considered
| Possible knife form | When it may be considered | What must be confirmed |
|---|---|---|
| Existing matched shear-slitting pair | Only where the installed station supports the complete labelstock stack. | Confirm overlap, side load, holder, liner condition and both retained edges. |
| Existing guided fixed slitter | Only where support and exposure suit the declared facestock, adhesive and liner. | Confirm blade exposure, protected-face contact, liner penetration and rewind behavior. |
Information to Send for Technical Review
You do not need to know the exact blade name. Send the available workpiece, machine, current-knife and cut-result information so the application can be reviewed against a drawing or sample.
- Supplier designation and whether the supplied object is master labelstock, printed intermediate, finished tape or another documented construction
- Facestock material and thickness, indication or release layer, coloured or metallic layer and protected face
- Adhesive type, coat condition, liner material and thickness, release direction and any print or authentication datum
- Parent width, core, roll diameter, unwind face, winding direction, storage and approved conditioning state
- Target width, length or CAD feature, datum and accepted edge, adhesive, liner, print and particulate limits
- Existing unwind, guide, support, holder, blade, anvil, rewind, cut-off and waste-path drawings plus the current tool
- Labelled accepted and rejected samples from the same construction, lot and converting state
- Trial quantity, downstream label-application and tamper-validation ownership, cleaning, packing and annual demand

Questions About This Cutting Application
Can a blade form be selected from the term “security VOID tamper-indicating labelstock” alone?
No. Confirm grade, complete layer stack, process stage, protected faces, installed interface and accepted and rejected samples.
Does a clean slit prove tamper-indicating performance?
No. The converted label and its intended substrate require separate application and tamper validation.
Can an unprinted sample approve register to a security feature?
No. Use production-representative material with the actual datum.
Public references and scope
These public sources provide material, cutting-method or safety context for this guide. Supplier pages describe their own materials or equipment; they do not establish a MEIRENTE blade specification or performance claim. Confirm the actual grade, machine setup and required cut with a drawing or sample.
