Structural confidentiality: The second and third sections are sealed together using colored adhesive, forming a sealed bag. Users need to tear the seal to view the contents, and once torn, it cannot be restored.
Printing confidentiality: Both sides are covered with security patterns (such as mesh patterns or encrypted designs) to prevent perspective effects; multi-color printing is optional to enhance the anti-counterfeiting feature.
Anti-paper jam design: The paper has high stiffness and little dust. The three-pass synchronous paper feeding does not get stuck.
Bank security envelopes (also known as password envelopes / confidential letters) are a type of three-part carbonless copy paper specially designed for financial, securities, insurance and other institutions. They are used to print sensitive information such as bank card passwords and salary details.
Through physical sealing and confidential printing techniques, the security and privacy of the data transmission process are ensured.
