As the name implies, security envelopes are designed to keep the contents of the envelope safe from undetectable identity theft and protect personal information with interior cross-hatched design patterns that are impossible to read through. Plain white envelopes can be transparent when held up to a light. Security envelopes prevent unauthorized access to confidential and private documents using either blue or black ink cross-hatching and other security features such as tamper-evident seals, security tint, and especially durable materials to prevent tearing and punctures. They are used in cases when business must send important contracts, bank statements, medical records, government notifications, or money in the form of checks, money orders, or travelers checks. Security envelopes are an alternative to adding an extra sheet of paper and preferred to protect confidentiality and obscure the text and numbers inside the envelope that could include a social security number, birth date, driver’s license number, financial account numbers, and personal health information. Security envelopes are available in varying sizes and with different features. Padded security envelopes provide extra cushioning and protection for delicate items, while poly security envelopes provide water-and-tear-resistant durability. Businesses that value the privacy of the recipient should choose from among the many suitable security envelope options available, taking the level of security, material durability, and cost of envelope and mailing into account when deciding on the right security envelope.
