Envelope (1) for small goods comprised of contact areas of at least single-layer inner and outer laminate structures, in which parts projecting beyond ends of a column of packed goods are shaped as tightly closed butt-end caps (2). A reed flap (3), which is suitable for repeated opening and closing and in which a line of perforation (5) confines the reed (4) is located nearby at least one of said butt-end caps. A flexible wraping material for the envelope is shaped as a long-length band that is comprised of many prospective uniform envelopes' blank-segments. Each blank-segment has contact areas of at least single-layer inner and outer laminate structures and a zone meant for formation of a prospective reed flap (4) confined by a line of perforation (5). Each line of perforation is made only in the outer laminate structure, and each prospective reed is placed initially onto the inner laminate structure. This decreases substantially the probability of accidental ruptures of filled envelopes. |
