Containers for letters to be mailed

You're referring to envelopes! Here are some common types of containers used for mailing letters:

  1. Standard Envelopes: These are the most common type of envelope, available in various sizes (e.g., #10, A2, A6) and materials (e.g., paper, plastic, or recycled).
  2. Window Envelopes: These envelopes have a transparent window that allows the recipient's address to be visible, making it easier to read and process.
  3. Clamshell Envelopes: These envelopes have a hinged flap that opens like a clamshell, providing extra protection for sensitive documents.
  4. Tyvek Envelopes: Made from DuPont's Tyvek material, these envelopes are durable, water-resistant, and often used for mailing important documents.
  5. Padded Envelopes: These envelopes have a cushioning material (e.g., bubble wrap, foam) to protect fragile items during transit.
  6. Jiffy Bags: These are lightweight, padded envelopes made from paper or plastic, often used for mailing small items like documents, photos, or gifts.
  7. Mailing Tubes: These are cylindrical containers made from paper or plastic, used for mailing large or irregularly shaped items like posters, maps, or artwork.
  8. Pouches: These are flexible, sealed containers made from plastic or fabric, often used for mailing small, delicate items like jewelry or electronics.
  9. Self-Seal Envelopes: These envelopes have a adhesive strip that seals the flap, making it easy to close and mail without needing a stamp or glue.
  10. Custom Envelopes: These are envelopes designed specifically for a particular purpose or industry, such as envelopes with special security features or custom sizes.

These are just a few examples of the many types of containers used for mailing letters. The choice of envelope often depends on the type of item being mailed, the level of protection required, and the desired appearance.
