Import China Factory Yellow Plastic Security Seal — Buy in Bulk from Supplier in China

The China Factory Yellow Plastic Security Seal is a polymer seal designed for tamper‑evident closure of containers and transport units. It is moulded from a blend of polypropylene (PP) and polyethylene (PE) as stated by the supplier. Lengths are offered from 150 mm up to 700 mm, allowing selection to match cable, pipe or strap dimensions. The seal colour is standard yellow and the design incorporates either a pull‑tight or self‑locking mechanism that engages without tools.

PP and PE provide good chemical resistance and are fully recyclable, matching typical industry practice for disposable security devices. The pull‑tight design creates a permanent deformation that can only be released with bolt or cable cutters, a safety feature common to high‑security seals. Thermal stamping or laser engraving can be applied, enabling batch numbers or barcodes, which complies with standard tracking requirements in logistics. Typical tensile strength for PP‑based seals ranges from 10 to 15 MPa, sufficient for most container sealing applications. Standard industry specifications also call for a minimum breaking torque of 3 Nm for yellow seals, though the supplier does not publish a specific value.

These seals are used on trucks, tanks, doors, airline luggage and food carts, making them suitable for freight forwarders, warehouse operators and courier services. Buyers should confirm the minimum order quantity, Incoterms and payment conditions directly with the company, as the listing does not disclose those details.
