Paper mailer bags and tamper-proof courier bags are both used for shipping and mailing items, but there are some key differences between them.
Paper mailer bags are made of paper and are often used for shipping lightweight items like clothing, documents, or small products. They usually have a self-sealing adhesive strip and may or may not have padding to protect the contents. Paper mailer bags are not designed to be tamper-proof and can be opened relatively easily.
Tamper-proof courier bags, on the other hand, are made of thicker, more durable materials like plastic or polyethylene. They are designed to be resistant to tearing, punctures, and tampering. Tamper-proof courier bags often have additional security features like high-strength adhesive closures, tamper-evident seals, or serial numbers to ensure that the contents of the bag are not tampered with during shipping. They are commonly used for shipping valuable or sensitive items like electronics, jewelry, or confidential documents.
