01 / FACESTOCK
PET Facestock Specification & Control
PET film thickness, surface condition and dimensional consistency are controlled to support stable coating, printing and downstream converting performance.
HANKSEC / QUALITY ASSURANCE
Security Label Material Quality Assurance
Quality assurance means controlling the complete material system — from incoming components and in-process conditions to functional performance and pre-production qualification. Hanksec verifies material consistency before bulk production.
QUALITY FOUNDATION
Material Quality Starts With Controlled Inputs.
Security material performance depends on the interaction of the facestock, release liner, pressure-sensitive adhesive and functional coating system. Each input is selected and controlled for consistency, compatibility, downstream printing, converting stability and tamper-evident performance.
02 / RELEASE LINER
Release Liner Selection & Control
Release liner construction and release characteristics are selected to support stable release force, die cutting, matrix stripping, rewinding and dispensing.
03 / ADHESIVE
Pressure-Sensitive Acrylic Adhesive System
Acrylic pressure-sensitive adhesive is selected according to the application substrate, bonding conditions, service environment and required tamper-evident response.
04 / FORMULATION
In-House Functional Coating Formulation
In-house formulation capability supports adjustment of functional coating layers to achieve the required release behavior, printability and tamper-evident performance.
FUNCTIONAL MATERIAL TESTING
Five Material Performance Tests Before Bulk Production.
Visual inspection alone cannot confirm whether a security material will perform reliably. Qualification should evaluate adhesion, release behavior, converting stability, tamper response and print durability under relevant application conditions.
01
Peel Adhesion Test
Bonding Performance
Measure bonding performance on the intended substrate.
02
Release Force Test
Liner Separation
Verify stable facestock-to-liner release behavior.
03
Die Cutting & Matrix Stripping
Converting Stability
Verify die-cutting stability and clean matrix removal.
04
VOID Tamper Effect Test
Security Response
Confirm the specified full, partial or non-transfer response.
05
Printing / Barcode / Rub Test
Printed Durability
Check printability, barcode readability and rub resistance.
Peel / Release Performance Testing
Initial Adhesion Evaluation
Test Data & Measurement
In-Process Quality Monitoring
Material and process checks during production
IN-PROCESS QUALITY CONTROL
Control Quality Throughout the Material Process.
Quality control does not begin at final inspection. Key material inputs, coating consistency, registration, adhesive and release behavior, security response and finished-roll condition are monitored against defined process requirements throughout production.
01
Incoming Material Check
Verify key facestock, liner and adhesive inputs before production.
02
Coating & Registration Control
Monitor coating condition, registration and visual consistency.
03
Functional Performance Check
Check adhesion, release behavior and security-layer response.
04
Final Inspection & Release
Confirm finished-roll condition before packing and release.
PRE-PRODUCTION QUALIFICATION
Qualify the Material Under Actual Application Conditions.
Laboratory data is useful, but it cannot represent every substrate, printer or converting line. Before bulk production, sample qualification should reproduce the intended substrate, printing method and converting conditions as closely as practical.
From Sample Evaluation to Bulk Approval
Qualification should reflect the complete material construction and the customer's intended application and converting conditions.
01
Confirm Material Construction
Facestock · adhesive · liner · security construction
02
Test Actual Substrate
Adhesion and tamper response on the intended surface
03
Verify Printing Compatibility
Ink / ribbon compatibility, print quality and durability
04
Run Converting Trial
Die cutting · matrix stripping · rewinding · dispensing
05
Approve for Bulk Production
Confirm required performance before production scale-up
TEST DATA & QUALITY RECORDS
Recorded Test Data for Material Review
Recorded test data and technical records support sample comparison, specification review and communication between purchasing, technical and production teams.
FINAL RELEASE
Controlled Packing & Shipment
Released materials are packed according to the agreed supply format and transport requirements before shipment.
