1.Core function: Double protection. More than sealing.

1. Storm and Weather Protection Design

· The use of anti-UV modified PP / PE material, through 1000 hours of weathering test, can withstand heavy rain, exposure, salt spray and other harsh environments, -30C to 60C temperature difference without cracking, no deformation.

· The surface is coated with anti-splashing coating. Rain water falls down quickly to avoid the material aging caused by long-term moisture. It is suitable for outdoor logistics, open-air storage and other scenarios.

2. Tamper-proof lock technology

· Back-hook jagged lock: When tightened, it automatically freezes, and the lock needs to be destroyed to be dismantled. The broken part shows a clear jagged mark, which prevents the possibility of undamaged removal.

· Encryption type clasp structure: "click" sound when locking, bite depth up to 2.5mm, tensile strength up to 100 N, effective resistance to external forces tearing.

2. Material and technology: industrial-grade durability

· Basic material:

◦ PP (polypropylene): high rigidity, impact resistance, suitable for sealing heavy cargo (such as containers, truck trailers).

◦ PE (polyethylene): flexible and bendable, can wrap irregular objects (such as pipes, cables), -20 ℃ still maintains elasticity.

Upgrade the process:

◦ Thickened by 30% at the buckle area, with more than 10,000 fatigue tests without breaking;

◦ Laser engraving with unique number/QR code, supports traceability management, and realizes "one product, one code" anti-counterfeiting.

Typical application scenario

| Scenarios | Protection Needs | Product Benefits |

| Outdoor logistics and transportation | Rain Water Penetration, Artificial Opening during Transportation | Anti-splashing Material + Anti-release Lock Clasp, Full Guardian of Goods Safety

| Energy equipment sealed | Long-term weather resistance in open environment, against illegal operation | UV-resistant material + high-strength locking, service life ≥ 2 years |

Cold chain storage | high and low temperature alternation, high humidity | PE material resistant to low temperature embrittlement, seal does not fail |

| Transport of Hazardous Chemicals | Double Compliance requirements against leakage, tampering, and tampering | Trace of Fracture Traceable |

Specification and Customization: Adapting to Requirements

· Standard size:

◦ Length: 120mm (light), 250mm (general), 400mm (heavy);

◦ Width: 2-3mm (slim version), 4-6mm (enhanced version).

· Color options:

◦ In stock: red, blue, yellow, white (warning color first);

◦ Customization: Brand special color, transparent model, fluorescent model (minimum order quantity ≥ 1,000,000 pieces).

· Value-added services:

◦ Free sample: Confirm the locking force and printing effect;

◦ Fast Delivery: Regular orders dispatched within 48 hours

Quality certification and after-sales service

· Authoritative endorsement: through the ISO 9001 quality management system certification, ROHS environmental certification, CE safety certification;

· Aftersales Support:

◦ It is a non-human quality problem and there is no reason to replace it;

Provide tensile test and resistance to natural weathering test, support third party reinspection.
