Frequently Asked Questions

Q: How to choose suitable security seals for my application?

A: We provide three way for you to select security seals.

  1. Find out your industry sector, then choose the seals in the product table
  2. By the Item to Seal Table. We have list the items and the security seals can be used on it. Find out the right seals from the table
  3. By the Seal Features Table.

Q: Can we mark our logo and consecutive numbers on the seal?

A: Yes, we could print text, logo, white writing pad and also consecutive numbers on the seal. The default marking method is hot stamping. The consecutive numbers only could be marked by hot-stamping.

Q: What’s the benefit of the hot-stamping marking?

A: Hot stamping is the main technology used for marking the plastic security seals. The method guarantees for absolutely evident seal marking. In case of any efforts to remove or manipulate the marking, it is always possible using mechanoscopic techniques to prove the existence of original marking. It is possible to print unified size text, graphical logo and up to 7 digit number of unified size. The print color can be selected, typical colors are white and black, other colors are available upon request and are subject to possible technological limitations. The only print limitation of hot stamping technology is the impossibility to print bar codes.

Q: How can we print bar codes?

A: We can use Laser engraving to mark the bar codes. It produces a resistant print which can be formed from even very thin lines, have complicated logos or symbols. It is of course possible to print both number and bar code. The print is always monochromatic and the color of print can not be selected. Marking of barcodes for small series also can by ink jet

Q: Can we choose any color of the seal printing bar codes?

A: For marking seals by laser, only some colors of seals are available due to the technical limitations of the barcode scanners - the colors are yellow, white, red, grey. Other colors may be available, but require individual testing. Light colors are marked directly onto the seal, darker colors use extra white background for higher contrast and better readability. Use of the laser marking is suitable for applications requiring more complicated seal marking, bar code and increased mechanical resistance of the marking.

Q: Can we choose any kinds of bar codes?

A: It is the possibility to mark standard 1D and 2D barcode types (Code 128, Interleave 2/5, Code 39, EAN 13, Data matrix).

Q: Any other marking methods? And what’s the merit and demerits?

A: Thermoprinting
Thermo-print marking provides great versatility in printing. The seal can be marked with logo, number, bar code or any other graphical symbol the customer requires. The print color can be selected. This technology is suitable for applications that are not exposed to high mechanical friction or chemically aggressive environment (solvents and oil products). The print is resistant to normal scratching.
Ink Jet printing
The seals also can be marked by means of precession ink jet printing. This technology is used only for printing barcodes.

Q: Quality guarantee and Unique number guarantee

A: During each production stage, the seals are constantly monitored to assure maximum quality of the product. Marking being very important to assure tracability, every produced seal is either visually or electronically checked for possible print defects.

  Accory maintains a database of all produced seals, their marking and numbering. We can guarantee to our customers that we will not produce a duplicate seal (two seals of the same color, marking and number).

Q: WHAT IS ISO 17712?

The points what must be tested according to ISO 17712 as following:

  1. Tensile strength
    Tensile Test Data: High Security Seal Requirement: 10.0 kN
  2. Shear
    Shear Test Data: High Security Seal Requirement: 341 kgf minimum
  3. Bend
    Bending Test Data: High Security Requirement ? Minimum 50 Nm to failure on rigid seal
  4. Impact
    Impact Test Data: High Security Seal Requirement: Impact Load ? 40.68 Joules
They must be tested at different temperature
The test report must be validated by a certified third party


Q: Does your products compliant ISO 17712?

A: Our bolt seals are all ISO 17712 compliant.

Q: Do you have the certificate of C-TPAT?

A: We are trying to apply the certificate of US CUSTOMS C-TPAT, but the USCBP C-TPAT guidelines there is only one reference to the use of security seals and this states that:
“A high security seal must be affixed to all loaded C-TPAT importer containers bound for the U.S. All seals must meet or exceed the current PAS ISO 17712 standards for high security seals.”
You will note from the C-TPAT wording there is no such thing as a “C-TPAT compliant seal” there is only the single reference to IS 17712 seals – check it out for yourself by visitng the following link:
