FIELD: various technological processes.
SUBSTANCE: invention relates to bags of single-edge format and processed highly impermeable film structures used for production of bags. Tightly sealed single-edge bag has front panel (210), rear panel (220), a first side panel and a second side panel formed from a processed highly impermeable packaging film. Processed highly impermeable packaging film has outer film (110) based on polyethylene, oriented in machine direction, and inner film (120) based on polyethylene. Outer film (110) has secant modulus of elasticity in transverse direction and secant modulus of elasticity in machine direction, each from 1,000 to 1,800 N/mm2.
EFFECT: providing protection of products in case of falling, as well as ease of opening and closing.
