❓ Sourcing & Application FAQs (B2B)

Q: What is the purpose of the "stainless steel locking insert" in the plastic seal?

A: The built-in stainless steel insert provides a stronger one-way locking grip. Once the seal is threaded and pulled tight, the metal insert firmly grips the plastic tail, preventing the seal from being pulled back. Compared to pure plastic locking mechanisms, it offers a higher security level of tamper-evident protection.

Q: Is laser custom printing available for Low MOQ orders?

A: Yes. With our complete source factory production line, we can arrange laser engraving of your company name, serial numbers, or barcodes even for small batch orders. Please contact us to confirm specific customization MOQs and lead times.

Q: Are different lengths of plastic seals available? How should I choose?

A: Our product line covers various lengths from 170mm to 600mm. Short lengths are suitable for space-limited equipment (e.g., bank cash boxes, aviation catering carts), while medium to long lengths are widely used for courier bags, cold chain transport, and warehouse doors. You can choose based on your actual binding circumference.
