FIELD: aseptic packages, namely for packages for long-term storage of food products such as milk, vine, juice and so on. ^ SUBSTANCE: method for package 2 manufacturing of sleeve 3 of heat-sealable sheet packing material fed along vertical line A and continuously filled with food product involves pressure squeezing sleeve 3 in cross-sectional areas spaced equal distances one from another with two pair of clamps 8,9 cyclically acting on the sleeve 3; cutting the sleeve 3 in each cross-sectional area along corresponding separation line L; heat-sealing packing material by inducing electrical loss currents from both opposite sides of the sleeve through product along lines substantially symmetric relative separation line L. Device for above method realization includes control means for clamps, sealing means and cutting means operation to perform above operations in described sequence. ^ EFFECT: increased efficiency, increased shelf life of food products. ^ 11 cl, 6 dwg |
