Plastic seals are durable security devices made primarily from high-strength engineering plastics, specifically designed to effectively prevent counterfeiting, theft, unauthorized access, and tampering. They are widely used across various industries and commercial applications, playing an essential role in ensuring the integrity, authenticity, and safety of goods during transportation, storage, and daily use. The plastic seal is a single-use self-locking security seal that cannot be reopened once applied, providing reliable and visible tamper evidence.
Their colors are highly diverse and flexible, allowing full customization according to customer requirements, including color selection, logo printing, barcode printing, and serial number marking for tracking and identification purposes. The size specifications are also highly varied to meet different industrial and packaging needs. In addition, the plastic seals feature adjustable lengths and strong locking structures, providing enhanced anti-counterfeiting and anti-tampering protection performance.
They are mainly used in logistics transportation and supply chain management, medical equipment sealing, warehouse storage systems, and industrial packaging fields. They are also widely applied for special sealing requirements of video equipment products, beverage packaging security, as well as plastic identification labels for bags, clothing, and various consumer goods packaging applications.
