Product Introduction

Crisp Variable Serial Number Printing

We ensure every unique serial number, alphanumeric sequence, and product specification is printed with extreme sharpness. Advanced digital thermal printing guarantees that ultra-fine legal text, sequence numbers, and regulatory certification logos remain 100% legible for life-cycle tracking and product authentication.

Premium Brushed Gold PET Durability

Engineered with a high-end metallic finish, our custom SN labels utilize heavy-duty Brushed Gold PET film. This material delivers a sophisticated aesthetic while providing superior resistance against chemical solvents, oil stains, high temperatures, friction, and long-term surface wear.

High-Tack Permanent Adhesion

To ensure serial numbers remain permanently affixed throughout the product lifecycle, we apply industrial-grade solvent acrylic adhesive. It forms a powerful bond on curved metal, textured electronics casing, equipment enclosures, and high-temperature surfaces without edge lifting.

Product Materials

Materials

Art Paper

With a smooth surface, high transparency, and good water and oil resistance. It is commonly used in packaging, labeling, and electronic products.

Textured Paper

Textured paper feature a distinctive surface feel that adds depth, elegance, and a premium tactile experience to packaging. They are ideal for specialty brands looking to create a sophisticated visual impact.

Kraft Paper

Kraft paper offer a natural, eco-friendly appearance with a unique textured feel, making products look more organic and handcrafted. They are ideal for brands seeking a rustic, sustainable, and premium packaging style.

Clear BOPP

Clear BOPP labels provide a transparent, “no-label” appearance that allows the product color and packaging design to show through. They offer excellent waterproof performance and durability.

Matte BOPP

Matte BOPP labels offer a smooth, non-reflective surface with a soft and elegant appearance. They combine premium visual appeal with strong waterproof and scratch-resistant performance.

White BOPP

White BOPP labels feature a clean, bright surface with excellent print clarity and color performance. They are durable, moisture-resistant, and suitable for different product applications.

PET (waterproof)

With a smooth surface and excellent print performance.It offers exceptional durability, heat resistance, and chemical resistance, making them suitable for demanding environments.

Holographic

It feature a unique rainbow-like reflective effect that creates eye-catching visual appeal and a premium appearance.

Silver PET

Silver PET naturally provides a bright metallic finish that creates a luxurious and high-end visual effect.

Production Process

Gold Brushed

Our Brushed Gold PET film upgrades standard SN labels into metallic, metal-like serial plates. The brushed texture eliminates harsh reflections while delivering a high-end look for electronics and machinery.

High-resolution printing guarantees that unique serial numbers and legal text remain sharp and high-contrast. The durable film surface is scratch-resistant and fingerprint-proof for long-term wear.

Waterproof

Made from high-density PET synthetic material, these SN labels are 100% waterproof and moisture-resistant. They won’t tear, peel, or disintegrate even in wet or outdoor environments.

The protective topcoat prevents ink smudging or bleeding from rain, steam, and liquid immersion. Paired with heavy-duty adhesive, the labels remain firmly affixed throughout the product lifecycle.

Durability of Custom SN Labels for Industrial Environment

SN labels enable each product to be uniquely identified for purposes of production traceability, maintenance of assets, verification of warranty and for purposes of recall.
If the label is fall off or becomes unreadable,the unit cannot be identified, resulting in voided warranty, failed targeted recall, disordered inventory and maintenance management, and potential non-compliance issues, bringing safety and business risks.

Our custom SN label is printed on PET material. This material is extremely hard and tear resistant. It also has an excellent temperature and chemical resistance.
The UV ink printing of the printed content of SN labels prevents from blurring or peeling off due to friction, chemical cleaning, or weather conditions. By producing a thick layer of solvent-proof and scratch-resistant ink, UV ink printing allows the printed content to remain unchanged in any situation.
If peeling due to environmental influences is a problem for your SN labels, acrylic adhesive or weather-resistant adhesive might be the solution for you. With these adhesives your labels will adhere very well to all sorts of surfaces (metal, plastic,fiberglass etc.) and will not curl up even in tough workshop.

FAQ

Can you print high-density variable serial numbers and micro text clearly?

Yes, absolutely. We utilize high-resolution digital thermal and UV printing technology specifically calibrated for variable data. This ensures that unique serial numbers, sequential alphanumeric codes, micro text, and fine line specification logos remain sharp, ultra-legible, and smudge-free across your entire production run.

What are the key advantages of choosing Brushed Gold PET for SN labels?

Brushed Gold PET combines high-end luxury aesthetic with rugged industrial durability. It gives your machinery or electronic products a premium metal nameplate look while offering superior resistance to chemical solvents, motor oils, high operating temperatures, and surface abrasion without fading or tarnishing.

How do you ensure there are no duplicate or missing serial numbers in bulk orders?

We implement automated inline optical verification systems during manufacturing. Every printed sequential serial number is cross-checked against your database list in real time to guarantee 100% accuracy, zero duplicate numbers, and precise sequential continuity for smooth inventory management.

Can these gold SN labels include tamper-evident features for warranty protection?

Yes. To protect your brand from warranty fraud or unauthorized label transfer, we can integrate tamper-evident properties into metallic PET materials, such as “VOID” pattern residues upon removal or destructible substrate options that fracture if peeled.

Will the adhesive stick permanently to textured plastics or curved equipment casings?

Yes. Standard adhesives can lift on low-surface-energy (LSE) materials. We engineer our Brushed Gold PET SN labels with heavy-duty, high-tack solvent acrylic adhesive that forms an instant, permanent bond to powder-coated metal, textured plastic housings, and curved equipment surfaces without edge lifting.

What is your MOQ, and can I test Brushed Gold PET sample labels on my products?

We offer flexible MOQs suitable for both initial prototype runs and large-scale industrial production. We also provide material sample kits and pre-production proof samples so you can test adhesive bonding, chemical exposure, and physical appearance directly on your equipment before commencing mass production.
