Plastic seals are security devices made primarily from engineering plastics, designed to prevent counterfeiting, theft, and tampering. They are widely used across various industries and applications, with the core function of ensuring the integrity and safety of items during transportation or use. The plastic seal is a one-time use self-locking seal. Its colors are highly diverse, allowing for customization of colors and printing of logos. The size specifications are also quite varied. The plastic seals have adjustable lengths and possess anti-counterfeiting and anti-tampering functions. They are mainly used in logistics transportation, medical and storage fields, as well as for special sealing of video and beverage products, and plastic labels for bags and clothes.
