SWLABEL pitches VOID labels for industrial tamper evidence

Zhejiang Shawei Digital Technology Co., Ltd. is promoting industrial VOID labels as a low-cost way to expose tampering, protect assets and support compliance across manufacturing, logistics and regulated supply chains. The company is positioning its digital-print-compatible materials for small-batch customization, variable data tracking and a range of industrial substrates.

Why it matters: - Industrial operators face warranty disputes, compliance gaps and financial losses when seals fail to show signs of interference. - VOID labels can provide visible tamper evidence for electronics, pharmaceuticals, calibration equipment and reusable shipping containers. - The approach is designed to help companies verify authenticity and maintain chain of custody without relying on more expensive security systems.

What happened: - Zhejiang Shawei Digital Technology Co., Ltd. promoted itself as a reliable industrial VOID label manufacturer. - The company outlined its tamper-evident label materials and custom digital printing capabilities in Jiaxing, China, on Sept. 4, 2026. - The company directed technical inquiries and sample requests to its official website: More information.

The details: - VOID labels are described in three transfer types: partial transfer, total transfer and non-transfer. - Partial transfer labels leave a permanent word or pattern on the substrate and retain some residue on the face film. - Total transfer labels deposit the hidden text onto the target surface. - Non-transfer labels reveal the hidden text within the label layers and leave no residue on the object. - SWLABEL says its materials are compatible with HP Indigo, UV Inkjet, Memjet and high-speed laser printers. - The company says this allows direct digital printing, including variable data printing, serialization and QR codes, without traditional printing plates. - The company says its substrate thickness range runs from 50um to 450um. - SWLABEL says it calibrates face-film modulus and adhesive cross-linking density to trigger the hidden VOID message under minimal peel force. - The company says it has more than 22 years of production and application experience. - SWLABEL offers raw materials in jumbo rolls, mini rolls, pre-cut sheets and A3 or A4 formats.

Between the lines: - The pitch blends security labeling with digital customization, which can matter for smaller production runs that do not justify plate-based printing. - The emphasis on multiple substrates suggests the company is targeting manufacturers that use metals, plastics, glass and composite materials. - The application examples point to a broader trend: tamper-evident labels are being used not just for security, but also for tracking and brand identification.

What's next: - Industrial buyers can request custom VOID label sample sheets for validation testing. - The company is positioning the labels for both automated application systems and manual sealing operations. - Wider adoption will likely depend on how well the materials perform across real-world thermal, mechanical and surface conditions.

The bottom line: - SWLABEL is betting that industrial customers want tamper evidence, digital traceability and flexible printing in one label platform.
