RESEALED LAMINATE FOR HEAT-SEALED BAG Russian patent published in 2013 - IPC B32B27/00 B32B27/08 B65B61/02 B65B61/18 B65D83/08 

FIELD: process engineering.

SUBSTANCE: invention relates to resealing of laminate packages. Resealed laminate comprises outer layer making the outer surface, adhesive-sensitive layer adjoining aforesaid layer, inner sealing layer making the inner surface, film layer adjoining inner sealing layer and separation layer arranged between adhesive-sensitive layer and film layer. Separation layer gets, at least partially, in contact with adhesive pressure -sensitive layer. Inner surface forms an inner notch extending through sealing layer, film layer and separation layer to form the flap inner part. Outer surface makes an outer notch extending through outer layer and adhesive-pressure layer to make flap outer section. Flap inner and outer sections are attached to each other to make a positioning flap partially connected with packing laminate. Outer and inner notches form the area of resealing extending between said pouter and inner notches. Flap resealing area comprises the section of adhesive pressure-sensitive area while resealing area of packing laminate comprises separation layer section.

EFFECT: relatively low costs using high-speed and high-efficiency equipment.
