Container pull tight serial number plastic security seal for air freight

Description:

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.

Key Features

Durable PP + PE Construction

The ST8025 Plastic Seal is manufactured using a combination of polypropylene (PP) and polyethylene (PE), materials known for their durability and flexibility. This structure provides strong tensile performance while maintaining flexibility during installation.

The materials used in this Plastic Seal also offer resistance to moisture, chemicals, and temperature changes, making it suitable for indoor and outdoor environments.

High Security Locking Mechanism

This Plastic Seal is designed with an integrated locking chamber that ensures once the seal is applied, it cannot be removed without visible damage. The tamper-evident design helps prevent unauthorized access and protects cargo integrity during transportation and storage.

The locking system of the Plastic Seal provides a reliable security barrier that allows operators to quickly identify any signs of tampering.

Large Marking Area for Identification

The ST8025 Plastic Seal features a marking area of 25 × 70 mm, offering ample space for customized identification information. This large surface allows clear printing of serial numbers, company logos, barcodes, or QR codes.

The clear marking area improves cargo tracking efficiency and simplifies inventory control within complex supply chain systems.

Flexible Length Options

The Plastic Seal is available in 300 mm and 400 mm total lengths, allowing users to select the appropriate size for different sealing requirements. Whether sealing logistics bags, containers, cages, or utility equipment, the adjustable length ensures convenient installation.

Multiple Color Options

To support operational classification and visual identification, the Plastic Seal is available in several standard colors including red, yellow, blue, green, and white. Custom colors can also be produced to match company branding or operational requirements.

Different color options help organizations quickly identify sealed items and improve workflow efficiency.

Typical applications include truck doors, trailer doors, totes, vales, airline catering carts, coin bags, inner drum bags, storage bags, and any container with a hasp or loops.Plastic seals are widely used to secure containers, tanker trucks, and courier packaging bags, preventing illegal opening or tampering with goods during transit. Their single-use design and unique numbering ensure that any manual unsealing leaves clear evidence, thereby safeguarding transportation security. In courier packages and e-commerce logistics, single-use anti-counterfeiting plastic seals (also known as security tags) are commonly adopted. Featuring unique textures or printable corporate logos, they enhance brand recognition while strengthening consumer trust.
