What are the typical applications for plastic anti-tamper seals for shipping containers?

I. Container and Logistics Transportation Sector (Core Scenarios)
This is its most fundamental and typical application:
Maritime / Land Transport Containers: Used for container door locking mechanisms, serving as proof for customs supervision and cargo handover, preventing unauthorized opening, cargo substitution, or theft during transit, while meeting compliance requirements for import and export trade.
Box Trucks / Refrigerated Trucks: Used to secure the rear cargo door latches, ensuring the safety of goods during long-haul and urban distribution, particularly for high-value and temperature-controlled perishable goods.
Logistics Reusable Containers / Express Package Sealing: Used to seal reusable containers and high-value express packages, preventing unauthorized opening en route, and enabling handover verification through unique identification numbers.
II. Financial and Cash-in-Transit Industries
Bank Cash Boxes / Cash Bags: Used to seal cash-in-transit containers and branch cash boxes, ensuring that funds remain unopened throughout the entire journey from the vault to the branch; this is a critical component of security management in financial cash-in-transit operations.
Securities / Document Envelope Seals: Used to seal confidential documents and securities envelopes at banks and securities institutions, preventing information leaks or document tampering.
III. Customs and Regulatory Scenarios
Customs-Regulated Goods: Used as seals for containers holding bonded goods or goods in transit under customs supervision, serving as a mark of customs oversight and certifying that the goods have not been opened without authorization during the regulatory process.
Inspection and Quarantine Seals: Anti-counterfeiting seals are used on the transport packaging of certain imported and exported animal and plant products, as well as food items, to ensure that the goods have not been illegally tampered with or substituted.
IV. Energy, Chemical, and Special Industries
Petroleum/Chemical Tank Trucks: Seals are applied to the unloading ports and manhole covers of tanks transporting petroleum products and chemical raw materials to prevent unauthorized drainage or substitution of materials en route, thereby ensuring the quantity and quality of the raw materials.
Electricity/Telecommunications Equipment Enclosures: Seals are applied to outdoor electricity meter boxes, telecommunications base station cabinets, and cable junction boxes to prevent unauthorized opening, illegal tapping, or tampering with equipment parameters.
V. Retail, Pharmaceuticals, and Specially Regulated Scenarios
Pharmaceutical Cold Chain Transportation: Used to seal transport containers for medicines and vaccines. When used in conjunction with temperature labels, they provide “seal + temperature” dual control to prevent temperature control failures or the substitution of pharmaceuticals.
Transportation of Valuables / Luxury Goods: Used as packaging seals for high-value goods such as luxury items and jewelry. Combined with customized anti-counterfeiting markings, they prevent goods from being swapped during transit.
E-commerce Returns and Exchanges: Used to seal boxes containing returned e-commerce items, preventing consumers from maliciously swapping goods and serving as proof of the product’s authenticity and condition.
Public Utilities and Security Control: Used as lead seals for water, electricity, and gas meters to prevent unauthorized tampering and theft of utilities; they can also be used as anti-tamper seals for fire hydrants and other outdoor public facilities.
