FIELD: chemistry.SUBSTANCE: invention relates to non-foil packing laminate for aseptic packing liquid food product. Laminate includes middle paper or carton layer, placed outermost, liquid-proof thermoweldable polyolefin layers and applied on internal side of paper or carton layer impermeable for gaseous oxygen layer, formed as a result of applying liquid film coating from liquid gas-impermeable composition and further drying. Liquid composition contains polymer binding agent, dispersed or dissolved in liquid medium. Laminate additionally includes layer of matrix polymer on polyolefin base together with particles of inorganic filling agent, distributed in it, and inorganic particles also dispersed in gas-impermeable layer of liquid gas-impermeable composition. Invention also relates to method of producing packing laminate and to packing container, manufactured from packing laminate.EFFECT: invention makes it possible to produce non-foil paper or carton-based packing laminate with good characteristics of gas-permeability, impermeability to water vapour and internal adhesion in profitable way.15 cl, 11 dwg, 1 tbl, 1 ex |
