borítok

Borítok is the Hungarian term for an envelope, a flat, rectangular container used to enclose letters or documents for mailing or storage. It is typically made of paper or light cardstock and closed with a sealing flap that uses gum, moisture-activated adhesive, or a self-sealing strip. Some boríték have a transparent window to show the address.

Designs and sizes vary. Common formats include windowed and non-window envelopes, self-sealing varieties, and padded versions for fragile contents. International standards include sizes such as DL (110 × 220 mm), C5 (162 × 229 mm), C6 (114 × 162 mm), and C4 (229 × 324 mm); in North America, the #10 size (approximately 4.125 × 9.5 inches) is widely used.

Materials range from standard white and colored papers to recycled fibers, with coatings for durability or a premium finish. Some envelopes feature security properties such as tamper-evident linings or opaque interiors that prevent viewing contents through the paper. Window envelopes reveal the address printed on the contents or a label.

Uses include personal correspondence, business mail, invoices, and official documents. The address window reduces the need for separate address printing, while padding or security features help protect sensitive items.

The modern envelope emerged in the 19th and 20th centuries, with the introduction of gum- or self-sealing flaps and the widespread use of address windows, enabling faster and more economical mailings.
