الأسئلة الشائعة حول مواد ملصقات الأمان

What is a security label material?

A security label material is a pressure-sensitive material construction engineered to create visible evidence when removal, opening or manipulation is attempted. Depending on the construction, it may reveal a hidden VOID or OPENED message, transfer part of a security layer to the substrate, fracture during removal, or create another irreversible visual change.

بالنسبة للتوريد بين الشركات، قيّم النظام بالكامل: الطبقة الخارجية + طبقة الأمان الوظيفية + السطح القابل للطباعة + المادة اللاصقة الحساسة للضغط + بطانة الفصل. انظر كيف تعمل أنظمة مواد الملصقات الأمنية.

What is the difference between tamper-evident and “tamper-proof”?

تعني عبارة "مقاومة للعبث" أن التصميم يجعل أي محاولة للعبث مرئية بعد حدوثها. أما عبارة "مقاومة للعبث" فهي شائعة الاستخدام تجارياً، ولكن لا ينبغي اعتبار الختم الحساس للضغط بمثابة ضمانة على استحالة الوصول إليه في جميع الظروف.

For specification, define the evidence needed after removal: transferred message, label-side VOID effect, facestock destruction, carton-fiber tear or another permanent change.

كيف تعمل مادة ملصق VOID؟

تستخدم مادة VOID فصلًا مُتحكمًا فيه بين الطبقات الوظيفية. عند محاولة إزالتها، ينفصل الهيكل بطريقة مُصممة ويكشف عن نمط مخفي مثل VOID أو OPENED أو VOIDOPEN أو SECURITY أو شعار أو نص مخصص.

The message may remain mainly on the substrate, mainly on the removed label, or be divided between both surfaces. See ما هي مادة ملصق VOID؟ و Full / Partial / Non-Transfer comparison.

ما الفرق بين مادة ملصق VOID وملصق VOID النهائي؟

مادة ملصقات VOID هي مادة جاهزة للتحويل، تُقدم على شكل لفائف جامبو، أو لفائف مقطعة، أو صفائح، أو غيرها من أشكال المواد للطباعة والقطع. ملصق VOID النهائي مُحوّل مسبقًا إلى الحجم النهائي، وقد يتضمن طباعة، أو بيانات متغيرة، أو أرقامًا تسلسلية، أو أشكالًا مقطوعة.

Converters should define roll width, liner, core, printing method and downstream process. See the دليل لفائف مواد ملصقات VOID.

What is the difference between VOID and destructible security materials?

تُنتج البنى الفراغية أدلة على العبث بشكل رئيسي من خلال فصل الطبقات أو نقلها بشكل مُتحكم فيه. أما المواد القابلة للتلف فتُنتج أدلة بشكل رئيسي من خلال كسر الطبقة الخارجية، مما يجعل إزالتها بشكل نظيف وسليم أمرًا صعبًا.

Use VOID when a readable hidden message or controlled transfer effect is important. Consider destructible material when breakage of the label itself is the primary anti-removal mechanism. See مواد ملصقات قابلة للتلف و Converter Selection Guide.

How do I choose between full-transfer, partial-transfer and non-transfer VOID?

ابدأ بنتيجة الفحص المطلوبة. يُعدّ النقل الكامل خيارًا مناسبًا عند الحاجة إلى دليل مرئي قوي على السطح المُطبّق عليه. أما النقل الجزئي فيُقسّم الدليل بين الملصق المُزال والسطح الأساسي. بينما يُبقي عدم النقل الرسالة المخفية بشكل أساسي داخل الملصق المُزال مع تقليل الدليل المنقول الواضح على السطح المحمي.

These are selection directions, not universal guarantees. Final residue and message clarity depend on adhesive, substrate, dwell time and environment. Compare the constructions on أنواع مواد ملصقات VOID.

Does non-transfer VOID mean absolutely zero residue?

Not necessarily. “Non-transfer” describes the intended behavior of the security layer; it should not be interpreted as a universal guarantee of zero adhesive residue on every surface.

Actual residue can change with surface chemistry, coating, application pressure, dwell time, temperature and ageing. For sensitive or reusable surfaces, test the selected construction on the actual product. See the Non-Transfer VOID Buyer’s Guide.

Can the hidden VOID or OPENED message be customized?

نعم. يمكن للتركيبات المناسبة استخدام رسائل مخفية قياسية أو مخصصة مثل VOID، OPENED، VOIDOPEN، SECURITY، اسم الشركة، الشعار، نص تحذيري أو نمط متكرر.

Custom patterns may require artwork preparation, gravure-cylinder or tooling setup and a project-specific MOQ. Standard stock patterns are usually more suitable when fast sampling and flexible quantities are priorities.

Can the same VOID construction be used on every surface?

No. A material that activates correctly on glass or PET may behave differently on PP, PE, HDPE, coated cartons, painted metal or textured plastics. Adhesive wet-out, coating strength and surface energy all influence the final result.

Start with the actual substrate and required tamper response, then qualify samples. See the دليل لاصق ملصق مقاوم للعبث.

Can a VOID label be removed and reused without evidence?

A properly selected VOID construction is designed so removal produces an irreversible visual change. The original condition should not be restored simply by pressing the label back into place.

For critical projects, evaluate removal and reapplication attempts during sample qualification rather than relying only on a hand-peel demonstration.

Why is the application surface so important?

The adhesive must wet out and bond to the real substrate strongly enough to activate the intended security response. Two surfaces that look similar may behave differently because of surface energy, varnish, paint, texture, contamination, plasticizers or release agents.

This is why Hanksec recommends identifying the exact substrate before selecting the adhesive. See the دليل اختيار المواد اللاصقة والركائز.

What surfaces can security label materials be applied to?

اعتمادًا على المادة اللاصقة والبنية، قد تشمل التطبيقات الزجاج، وPET، وABS، وPC، وPP، وPE، وHDPE، والمعادن المطلية أو غير المطلية، والورق المقوى المطلي، والكرتون المموج، والأكريليك، وأغلفة الإلكترونيات والمكونات الصناعية.

A material family should not be assumed to work equally well on all these surfaces. Sample qualification on the real substrate remains the preferred approach.

Why are PP, PE and HDPE more difficult to label?

PP, PE and HDPE are commonly treated as lower-surface-energy plastics. Standard pressure-sensitive adhesives may not wet out these surfaces as effectively as higher-energy substrates such as glass, PET or clean metal.

The final choice should consider the exact molded or packaging surface, not only the polymer name. Check initial tack, developed adhesion, edge lifting and final tamper activation on the actual part.

Can security labels be used on rough, textured or powder-coated surfaces?

Yes, but roughness and texture reduce the true contact area between adhesive and substrate. Some applications may require a different adhesive chemistry, coat weight or more conformable material construction.

For rough cartons, textured plastics, powder-coated metal or slightly contaminated industrial surfaces, evaluate application pressure, dwell time, edge lifting and final tamper response before bulk approval.

What information should I provide for adhesive selection?

قم بتوفير مادة الركيزة، والتشطيب السطحي، والطلاء أو الدهان، ودرجة حرارة التطبيق، ودرجة حرارة الخدمة، والرطوبة أو التعرض للمواد الكيميائية، واستجابة العبث المطلوبة، ومتطلبات البقايا، وحجم الملصق، ووقت الانتظار المتوقع.

If possible, send a real substrate sample. A physical sample is often more useful than trying to select an adhesive from a generic material name alone.

Are security label materials printable?

تتوفر العديد من مواد ملصقات الأمان بسطح قابل للطباعة، أو طبقة أساسية، أو طبقة نهائية. وتعتمد التوافقية على نوع الحبر أو مسحوق الحبر أو شريط الطباعة ومنصة الطباعة المستخدمة.

A material can produce the correct VOID effect and still fail printing requirements if the surface chemistry is mismatched. See the دليل مواد ملصقات الأمان القابلة للطباعة.

Which printing methods can be used on security label materials?

اعتمادًا على معالجة السطح وبنية المنتج، يمكن تقييم المشاريع لأنظمة الطباعة الفلكسوغرافية بالأشعة فوق البنفسجية، والطباعة بالشاشة، والطباعة الأوفست، والطباعة الحرارية، والطباعة الرقمية المختارة، والطباعة النفاثة للحبر الصبغي، وأنظمة الطباعة الأخرى.

“Digital printable” or “inkjet printable” should not be treated as universal specifications. Confirm the actual printer, ink or toner, drying or curing conditions and downstream converting process.

Can VOID materials be printed by thermal transfer?

Yes, when the printable surface is compatible with the selected ribbon and printer settings. Qualification should include ribbon transfer, print density, scratch or rub resistance and barcode or QR readability.

The printable topcoat must also remain compatible with the security-layer behavior and downstream die cutting.

Can barcodes, QR codes, serial numbers and variable data be added?

نعم، يمكن للمواد المناسبة أن تحمل الرموز الشريطية، ورموز الاستجابة السريعة، والأرقام التسلسلية، والنصوص المتغيرة، والشعارات، ومعلومات التتبع. وتعتمد طريقة الطباعة والتحقق على ما إذا كان المحوّل يطبع داخليًا أم أن هانكسيك توفر تنسيقًا مُحوّلًا.

For barcode or QR applications, check scan readability after printing, handling and any required environmental exposure.

Why should a printed security material be tested again after converting?

Printing is only one part of the production system. Die cutting, matrix stripping, slitting, rewinding and dispensing can introduce additional mechanical stress.

Final qualification should confirm that print adhesion and readability remain acceptable and that the intended VOID or destructible response still works after converting. See the دليل مراقبة جودة مواد ملصقات الأمان.

Do pigment-inkjet systems require a special coating?

Often they do. A standard PET or security surface that works well with UV or flexographic ink may not provide suitable drying, dot definition or rub resistance with pigment inkjet.

For Epson ColorWorks and similar systems, review the دليل مواد الملصقات القابلة للطباعة باستخدام طابعات نفث الحبر and qualify the exact printer and ink set.

Do you supply security label materials in jumbo rolls and slit rolls?

نعم. اعتمادًا على تصميم المنتج ومتطلبات المشروع، يمكن توفير مواد ملصقات الأمان على شكل لفائف جامبو/ماستر، أو لفائف مقطعة، أو صفائح، أو تنسيقات محولة.

Converters should specify web width, roll length, core size, winding direction and release-liner requirement. See the دليل اختيار لفائف جامبو وسلت.

What should a label converter provide before ordering roll material?

Provide the printing process, required security construction, application substrate, web width, roll length, core size, winding direction, release liner, die-cutting method, approximate label geometry and estimated volume.

This helps separate material selection from machine-fit issues and reduces the risk of approving a small sample that does not run correctly on the production line.

Why is the release liner important?

تحمي بطانة الفصل المادة اللاصقة قبل التطبيق وتؤثر أيضًا على قوة الفصل، والقطع بالقالب، وإزالة المصفوفة، وإعادة اللف، ومعالجة الشريط، والتوزيع، واستقرار اللفة.

Changing liner type can change converting behavior even when facestock and adhesive remain the same. See Glassine vs PET Release Liner.

When should I choose glassine versus PET release liner?

Glassine is widely used for conventional label converting and can provide a practical balance of cost and processing performance. PET liner offers higher dimensional stability and tensile strength and may be useful for demanding high-speed converting or dispensing.

Neither is automatically better. Liner selection should be driven by the complete laminate, die-cutting method, web tension, dispensing geometry and machine conditions.

What is release force?

Release force is the force required to separate the pressure-sensitive laminate from its release liner under defined test conditions. Stable release behavior supports matrix stripping, dispensing and consistent web handling.

Release force should be evaluated together with the adhesive and liner rather than as an isolated number.

Why do matrix stripping or die-cutting problems occur with security materials?

Possible causes include incorrect die depth, fragile facestock, excessive web tension, narrow matrix, sharp label corners, adhesive flow, unstable release force or a liner that is not suitable for the process.

Security and destructible materials can have a narrower converting window than ordinary label stock. See the Destructible Material Converter Guide و دليل مراقبة الجودة.

What controls how easily a destructible material breaks?

Destructibility is influenced by facestock formulation, film thickness, elongation and brittleness, adhesive bond strength, application substrate, temperature, dwell time and label geometry.

The most fragile material is not automatically the best choice: extreme brittleness can create printing, die-cutting or matrix-stripping problems. Compare easy, medium and hard directions in the Destructible Label Material Rolls Guide.

Are destructible materials suitable for very small labels?

They can be, but small labels place greater demands on die-cutting accuracy, corner geometry, matrix stripping and dispensing. A very fragile facestock may provide strong anti-removal behavior while reducing converting stability.

Sample rolls should be evaluated at the intended label size and production speed.

Can holographic effects be combined with VOID tamper evidence?

Yes. A holographic optical layer can be combined with a VOID, partial-transfer, non-transfer or destructible construction depending on the project. Holographic appearance provides visible authentication, while the underlying security structure provides removal evidence.

See the Hologram Labels Selection Guide.

Are all hologram labels tamper-evident?

No. A holographic effect is an optical authentication feature; it does not automatically create tamper evidence. For removal evidence, the hologram must be combined with a VOID, destructible or other engineered tamper-response construction.

What are paper VOID materials used for?

Paper VOID materials use a paper-based facestock together with a controlled security and adhesive system. They are often considered for fiber-based cartons and paper packaging where buyers want the security label to integrate more naturally with the package construction.

See ملصقات ورقية فارغة: المواد، وأنواع النقل، والتطبيقات.

Do you offer high-temperature label materials for PCB and electronics?

Yes. High-temperature projects may use polyimide or application-specific PET constructions depending on the thermal profile, adhesive requirement and printing system.

The facestock temperature alone is not a finished-label rating. Confirm peak temperature, exposure time, repeated thermal cycles, substrate and print durability. See High-Temperature Polyimide Label Material.

What is a water-contact indicator label material?

Water-contact indicator material is designed to create a visible response after contact with a defined liquid or moisture condition. It can be used for electronics, warranty inspection and liquid-exposure verification.

Selection should consider target liquid, humidity environment, laminated or unlaminated construction, adhesive, application location and converting format. See the Water Contact Indicator Buyer’s Guide.

What tests should be performed before bulk production?

خمسة مجالات أساسية مفيدة بشكل خاص لمواد الأمان الموجهة للمحولات: قوة الالتصاق بالتقشير، وقوة التحرير، والقطع بالقالب وإزالة المصفوفة، والتحقق من استجابة العبث، والطباعة / الرمز الشريطي / اختبار الاحتكاك.

Additional checks may be needed for temperature, ageing, chemical exposure or application-specific risks. See the دليل مراقبة جودة مواد ملصقات الأمان and Hanksec ضمان الجودة صفحة.

Is a hand-peel test enough to approve a security material?

No. A hand-peel demonstration is useful for initial screening, but it does not represent production printing, die cutting, matrix stripping, web handling, automatic dispensing, longer dwell time or the full service environment.

Bulk approval should use representative production and end-use conditions wherever practical.

Why does dwell time matter?

Pressure-sensitive adhesive bonding can develop after application. A label peeled immediately may behave differently after several hours or days.

When comparing materials, keep application pressure, temperature and dwell time consistent so the tamper response is being compared under equivalent conditions.

Why should samples be tested on the customer’s actual substrate?

Laboratory panels cannot reproduce every varnish, paint, molded plastic, roughness, contamination or curvature found in production. These factors can change adhesion, residue behavior and VOID activation.

Actual-substrate testing is one of the most important steps before bulk production, particularly for sensitive surfaces or low-surface-energy plastics.

Does higher peel adhesion always mean better tamper evidence?

No. Peel adhesion measures one aspect of adhesive performance under defined conditions. Tamper evidence also depends on the facestock, functional security layer, transfer mechanism, substrate and removal behavior.

The goal is a controlled system that produces the required security response — not simply the highest possible peel value.

How does Hanksec control manufacturing consistency?

Hanksec’s manufacturing workflow includes security-layer production, coating, metallizing where required, printable-surface treatment, adhesive coating, release-liner lamination, slitting and quality inspection. The relevant controls depend on the material construction.

For a manufacturing overview, see القدرات التصنيعية.

What can be customized on security label materials?

اعتمادًا على عائلة المنتج، يمكن أن تشمل التخصيصات رسالة VOID / OPENED، أو الشعار أو النمط، أو سلوك النقل، أو مادة الوجه، أو اللون، أو السماكة، أو التأثير الهولوغرافي، أو الطبقة العلوية القابلة للطباعة، أو نظام اللصق، أو بطانة التحرير، أو عرض الشبكة، أو طول اللفة، أو حجم القلب، أو اتجاه اللف.

See the نظرة عامة على منتجات ومواد هانكسيك for the broader range.

Can the adhesive be customized for a specific substrate?

For selected projects, the adhesive direction can be matched to the intended substrate, surface condition and environment. Unusual plastics, sensitive surfaces, high/low temperature or special residue requirements should begin with application details and sample testing.

Can material thickness be customized?

Selected constructions can be supplied in different facestock thicknesses or project-specific structures. Thickness should not be changed independently because it can affect stiffness, die cutting, matrix stripping, rewinding, dispensing and tamper response.

Can I request samples before placing a bulk order?

Yes. Sample evaluation is strongly recommended for technical security-material projects. Standard material samples can be used for initial screening, while custom constructions may require artwork, tooling, plate/cylinder setup or sample charges depending on the project.

Use the اتصل بهانكسيك page to send the substrate, printing method and required tamper response with your sample request.

What is the MOQ?

There is no single MOQ for every security material. MOQ depends on whether the material is stock or custom, the roll format, hidden message, color, coating, adhesive, liner, holographic feature and manufacturing setup.

Standard stock constructions generally allow more flexible quantities than fully customized materials. Send the required specification first so MOQ can be quoted against the actual production route.

What information is needed for a quotation?

للحصول على أسرع عرض أسعار فني، يرجى تقديم ما يلي: مادة التطبيق، واستجابة العبث المطلوبة، وطريقة الطباعة، وشكل المادة أو اللفة، وعرض الشبكة، وطول اللفة، وحجم القلب، واتجاه اللف، وتفضيل البطانة، واللون، والرسالة المخصصة، والكمية المقدرة.

Photos or a physical sample of the application surface are also useful.

Do you supply only finished labels?

لا. يتمثل التموضع الأساسي لشركة Hanksec في كونها شركة مصنعة لمواد ملصقات الأمان ومزودة لحلول مقاومة التلاعب، حيث تقوم بتوريد مواد جاهزة للتحويل بالإضافة إلى تنسيقات محولة مختارة.

Label converters and printers can source jumbo or slit rolls for in-house printing and die cutting. End users with a finished-label requirement can confirm the required converting scope with the sales team.

Can tamper-evident materials be used for pharmaceutical and healthcare packaging?

Yes, tamper-verification materials can be used as one component of pharmaceutical and healthcare packaging systems for medicine cartons, bottles, vials, medical-device packaging and related applications.

A label by itself does not make the complete package compliant. The package design, substrate, application method and target-market requirements must be assessed together. See Pharmaceutical VOID Materials Guide.

Which security material is suitable for electronics and warranty protection?

Common starting directions include non-transfer or partial-transfer VOID when residue control matters, full-transfer VOID when stronger surface evidence is preferred, and destructible material when intact label removal should be difficult.

Final choice depends on device surface, service-access point, label size and inspection method. See ملصقات الأمان: أنواعها وموادها واختيارها.

What should be used for carton sealing and logistics security?

For cartons, parcels and shipping packaging, buyers may consider security packing tape, carton-sealing tamper labels or full/partial-transfer VOID constructions depending on the opening path and residue requirement.

See أشرطة تغليف أمنية مضادة للعبث و Security Packing Tape range.

How is security bag tape different from ordinary carton security tape?

Security bag tape is designed around flexible bag films and the bag-manufacturing process. Adhesive compatibility with HDPE, LDPE, co-extruded or laminated bag films can be very different from adhesion to corrugated carton.

Bag tape may also incorporate additional tamper-response features depending on security level. See the Security Bag Tape Selection Guide و Bag Tape Types.

When should I use an evidence bag instead of a label or tape?

An evidence or security bag is appropriate when the complete pouch must provide controlled one-time closure, identification and chain-of-custody support for documents, cash, evidence or sensitive contents.

See the Tamper Evident Security Bags Guide for bag structures, applications and selection criteria.

Can tamper-evident labels prevent theft or opening completely?

No pressure-sensitive seal should be treated as a physical lock. Its primary purpose is to make unauthorized opening, removal or manipulation more visible and harder to conceal.

For higher-risk systems, combine tamper evidence with appropriate packaging design, traceability, inspection procedures and other physical or digital controls.

Where should a new buyer start if they do not know which security material to choose?

Start with the Security Labels Selection Guide to define required tamper response, application substrate, residue requirement, printing method and supply format.

Then use the Hanksec Knowledge Center for deeper guides on adhesives, release liners, printing, roll formats, destructible materials and quality testing.

How does Hanksec recommend a material for a new project?

Define the application first: substrate, tamper-response objective, printing method, converting process, service environment and supply format. Suitable constructions can then be shortlisted for sample evaluation.

This application-first approach is designed to avoid choosing a material only from color, VOID pattern or a generic adhesive specification.

What should I send Hanksec for a technical evaluation?

أرسل صور التطبيق، ونوع الركيزة، والطلاء أو التشطيب السطحي، والمادة الحالية إن وجدت، وتأثير الأمان المطلوب، وطريقة الطباعة، وحجم الملصق النهائي، وعملية القطع بالقالب أو التحويل، ومواصفات اللفة، ونطاق درجة الحرارة والكمية المقدرة.
