In the field of tamper-evident packaging, material innovation has always been the core driver of industry progress. Recently, Shenzhen ZOLO Packaging Technology Co., Ltd. announced the successful development of a new anti-counterfeiting material series based on BOPP (biaxially oriented polypropylene) substrate, including tamper-evident labels, tamper-evident tapes, and specialty tamper-evident materials. This breakthrough not only enriches ZOLO's product portfolio but also offers brand customers a new anti-counterfeiting option that combines high performance, excellent aesthetics, and cost-effectiveness.
What is BOPP material?
BOPP film is produced through a biaxial stretching process, which aligns the molecular chains and gives the material outstanding physical properties: high tensile strength, tear resistance, puncture resistance, as well as superior gloss and transparency for vibrant, rich print colors. More importantly, BOPP features excellent water and moisture resistance, with a water vapor transmission rate (WVTR) below 5 g/m²·24h. Even under conditions such as cold chain logistics or humid storage, labels remain stable and anti-counterfeiting information stays clearly legible. The BOPP anti-counterfeiting material developed by ZOLO deeply integrates these inherent advantages of BOPP with the company's proprietary technologies—such as VOID (leave‑void) tamper evidence and optical anti‑counterfeiting—delivering uncompromised functionality while offering a wide range of anti‑counterfeiting material options.
Technical highlights: more than just a substrate, excellence in processing
ZOLO's R&D team overcame the industry challenges of BOPP's low surface energy and difficult ink adhesion. Through special corona treatment and primer coating technology, the surface tension of the BOPP film is stabilized above 42 dynes/cm, ensuring that anti‑counterfeiting inks and variable data (QR codes, serial numbers) adhere firmly and resist scratching and rubbing. At the same time, BOPP anti‑counterfeiting materials are compatible with various digital printing methods including thermal transfer and UV inkjet, meeting the traceability requirements of unique identifiers per product. For core anti‑counterfeiting performance, ZOLO BOPP materials support both full‑transfer and partial‑transfer VOID: tearing the label leaves an irreversible "VOID" mark, preventing any second use of the label. BOPP anti‑counterfeiting materials are widely applicable across many industries requiring secure packaging, such as electronics, pharmaceutical packaging, food and beverages, logistics and courier services, cosmetics, and luxury goods packaging.
A solid step forward in "true and hardcore anti‑counterfeiting"
The successful launch of this BOPP anti‑counterfeiting material further strengthens ZOLO's technological position on the path of "genuine, hardcore anti‑counterfeiting." Mr. Liu, General Manager of ZOLO, stated: "We have always insisted on avoiding performative anti‑counterfeiting. By combining materials, processes, and technology, we achieve multi‑layered protection. The introduction of our new BOPP material offers customers a more economical option without compromising anti‑counterfeiting performance. In the future, we will continue investing in specialty material R&D to help more brands eliminate counterfeit goods at the source."
