1, goal of the invention: the purpose of this invention is to provide a kind of method of utilizing co-extruding biaxial stretched heat-sealing polypropylene film that no carton carton of cigarettes is packed, when solving no carton carton of cigarettes film heat sealed package and the adhesion problems of parcel hyaline membrane by this method; Satisfy behind the no carton carton of cigarettes film FOLD AND PACK from the heat sealing requirement; Reach environmental requirement, reduce investment and use material cost, and promote material object the manifesting property again of selectivity, aesthetic property and little cigarette package of packing applicability, the use material broad of no carton bar coating.
2, technical scheme: for achieving the above object, coextruding heat sealing and two-way stretching polypropylene of the present invention does not have the method for making of carton carton of cigarettes with film, it is characterized in that this method for making is:
(1) selects co-extrusion heat-sealing type BOPP cigarette film, this cigarette film is carried out surperficial single face sided corona treatment;
(2) cigarette film printing roll surface is packed the heat-sealing band and reserve design, carry out cigarette-brand design and plate-making according to reservation schemes;
(3) select heatproof, antiseized printing ink, with the print roller after the plate-making co-extrusion heat-sealing BOPP not being had carton carton of cigarettes film prints, on the cigarette film after the printing, the heat-sealing band of reserving is the packing heat-sealing band after no carton carton of cigarettes film folds, this packing heat-sealing band ensures when no carton carton of cigarettes film seals and the parcel hyaline membrane does not stick together, and self good bonding;
(4) photoelectric tracking positioning system is installed on cigarette-packaging machine, is turned back to the electrical equipment servo-control system by seizure light district photosignal and position packing, no carton carton of cigarettes film printed patterns and reservation heat-sealing band position can accurately be packed put in place.
Because no carton carton of cigarettes film, in packing use, under certain pressurized condition of being heated, must can not stick together with the wrapping film of the parcel of the inside in bonding self taking place.Co-extrusion heat-sealing BOPP cigarette film can seal each other, and can not seal between the printing surface of co-extrusion heat-sealing BOPP cigarette film and the non-printing surface of co-extrusion heat-sealing BOPP.According to co-relation, for guaranteeing the hot sealing process requirement of no carton carton of cigarettes film, make simultaneously between bar bag film and the parcel hyaline membrane not stick together, utilize printing ink layer as antiseized barrier layer.BOPP carton of cigarettes film is printed the location, do not ensure when co-extrusion heat-sealing BOPP has the heat-sealing of carton carton of cigarettes film not produce adhesion with the parcel hyaline membrane; Utilize the reservation heat-sealing band of co-extrusion heat-sealing BOPP cigarette film printing, satisfy the packing heat-sealing requirement of no carton bar packing poststack.
