Plastic tamper seals plastic safety seals
This series of plastic anti-tamper sealing strips are made of high-quality polypropylene (PP) and polyethylene (PE) raw materials through one-piece injection molding. They feature excellent tensile strength and durability, and are suitable for one-time safety seals in scenarios such as containers, trucks, parcels, bank bags, fire-fighting equipment, electricity meter boxes, and medicine cabinets. The product design complies with international anti-tampering standards such as ISO 17712. Once locked, it can only be removed by violent destruction. After removal, there will be obvious marks, which can effectively prevent unauthorized opening or substitution.

1.High-strength anti-tampering structure: Unique inverted tooth locking design. Once locked, it cannot be pulled apart without damage, eliminating the need for repeated use.
2.Multiple types are available: We offer various structures such as cable tie type, pin type, pull-out type, and padlock type to meet different sealing requirements.
3.Bright color customization: More than ten standard colors such as red, yellow, blue, green, orange, white, black, etc. Supports color matching as needed, facilitating visual management in areas or teams.
4.Coding and printing service: Supports laser coding or thermal transfer printing, capable of printing serial numbers, barcodes, QR codes, company logos and text information, facilitating traceability and scanning verification.
5.Easy operation: It can be quickly locked by hand without tools. Some models are equipped with self-locking clasps that tighten immediately when pulled.
6.Passed safety tests: Low-temperature resistance, aging resistance, tensile strength and anti-disassembly performance have all been verified in the laboratory.
